- Today, we have an intriguing product to put to the test: a $30 Smartwatch that claims to accurately track glucose levels without the need for any blood samples. In this video, we'll compare this watch with its closest competitors to see if this innovative technology lives up to its promises.
Join me as I run a series of tests to compare the glucose readings of this affordable Smartwatch with a traditional Blood Glucose Monitor and the widely acclaimed Dexcom G6. We'll examine four scenarios: morning sugar, low sugar, high sugar, and steady-state sugar, using all three devices side by side. Get ready for some fascinating head-to-head action and multiple finger pricks to uncover the truth.

You know the other watch being in such close proximity, plus the fact that the Dexcom uses wireless technology, may have interfered with the performance of the other watch, though I doubt it. You shouldn't have worn both watches on the same wrist or even had the Dexcom on at all when testing the other watch.
Great advice. I actually did this in the following video.
th-cam.com/video/akucL_bnWhQ/w-d-xo.html
@@typ3meyes, I saw the other video, seemed promising at first. Too bad you didn't test the other watch this way, though I'm sure it would have been just as inaccurate. This is similar to the $30 watches that say they measure blood pressure. They absolutely do not measure BP accurately.
It's such a shame.
The smart watch doesn't work. Period.
Simply put, they cut out my pancreas, I was on the dexcom G7 and a pump, both were life saving for those who need them but like all technology, they would malfunction.. I would love to test it out on myself under normal daily activities. In the name of diabetes research...
Tks and good luck..

WARNING - This watch was pulled off of Amazon for being a scam
Really
I figured it was a scam
Ah... That's why I haven't been able to find any watch claiming such a function. I get to give up on it!
Thank you for explaining everything about a non-invasive glucose monitoring because I was interested before ❤️❤️
You're very welcome, Cecelia.
Thanks for this comparison. We should keep in mind that Dexcom is reading interstitial glucose, not blood glucose, so it is always about 20 minutes behind in any trend up or down. I was actually surprised by how close Dexcom was to the blood glucose meter. As long as they are close enough that you would make the same decision regarding insulin or carbs, these slight differences don't matter. I would say that Dexcom and Accu-Check were close enough as to be considered essentially the same.
As you said, though, the watch was so far off that it shouldn't be trusted. One would definitely have made different treatment decisions, some of them very different, based on the watch.
Alex (father of two with T1D, both using Dexcom ... one G6, the other G7)
Thank you, Alex, for the comment. Yes, I'm aware that the g6 reads interstitial fluid at 5 minute intervals that may have a 20-minute lag. I completely forgot to explain to the viewers that this test was meant to be conducted as an average consumer who didn't care for all the mumbo jumbo. Just a person who wants their devices to give them accurate numbers without having to jump through hoops. Could you imagine if that was a real thing? Maybe one day. Thanks again, and good luck to you
I'm currently using CVS branded meter and strips (made by Accu-Chek). I was using the Free Libre CGM, but Medicare doesn't cover it unless you are taking insulin-I'm not-and it was just too expensive. Since the CGMs do not measure blood glucose, but rather the intrastitial fluid, it's always going to be somewhat different. There's a 15 minute (or so) lag, if nothing else. I'm guessing that the watch is actually measuring something on or near the surface of the skin, therefore even more remotely related to blood glucose and even slower to respond. AFAIK, the non-invasive sensors that are seeking FDA approval use spectrographic techniques that shine light THROUGH part of the body, such as an earlobe or the web of skin between fingers, and thus sensing what is inside the body. I hope those reach the market soon.
Some medicare advantage plan does cover FS 2 & Dexcom G7 CGMs. My BCBS plan does & it covers test strips/meters. too. I am diabetic but not on insulin.
@@wdc1040 mine does not if you're not taking insulin. Next open enrollment, I'll look into that.
As a diabetic type 1 since 5-yo, where i live, state gives really bad devices, and no one gets libre or any sensor type, the others meansure they given is all dirty and open boxes, as well insulines, i just prefer to burn about half my incomming to pay and get a better health, i life with free style sensor always on me and running, lucky it never fail once, and never fall off, but for sure will be much better has a permanent device to measure glucose, as well will be great to have a functional pancreas to not depend on injections, but the treatments and cirurgic process now is really bad. I guess those light into body to see what is there could work, i just hope this be really accurated, even those blood sample home devices are not that accurate, sensor are laggy 15 minutes and each device has a range of accuracy. CGM use some programm modifications to try to fix the most possible values, but can be really off, mostly in first days, otherwise when a new blood path reach the device, once i was getting really well, but after a workout day, it start acting like day-1 when it is normally warming up, soo i noticed this type of situation any time i got difference of blood volume on the sensor region, just what i noticed, not sure the science under the hood
I am 91 years of age and have an accu chek guide me meter. I am so tired of finger pokes 3 times a day. A smart watch would be a blessing.
I agree. I sure hope that they come out with a reliable and affordable version very soon. Lord knows where not getting any younger
Just ask for free style libra2 you won’t have to prick you fingers again and you can trust the readings the watch is not medically approved in any country
Thank you for this. I am not full blown diabetic, but in the so-called pre diabetes range, and for the last year or so have been monitoring my blood sugar - and touch wood, with life style changes, I seem so far to be able to avoid medication. But as to your result that surprised you, you should have taken that one, using the same device again. Every now and again, I will get a result that would indicate I'm way off where I should be. But so far, if I immediately question whether it's something to do with the test strip, and repeat the test immediately, I find that that is the reason. For example. I once got a reading on 7.9 mmol/l, but when I tested again it was only something like 6.5 mmol/l (still a little high, but!). So there must be some test strips that have a problem. If, on the other hand, you take two such readings, and you confirm the high reading, then you know that you have a problem.
Thanks for the advice. I agree with you, and as a type 1 diabetic/paramedic. I've done my fare share of verification glucose checks. Unfortunately, since these are done at the fingers, which is the most distal part of our body, they are constantly inaccurate. In fact, 9 times out of 10, you will get a different number if you go down all 10 fingers. If you're willing to do it, a fairly accurate reading would be using the average of 3 different fingers to get a mostly accurate number.
Go carnivore, or at least keto. It'll bring those numbers down nicely
Thanks for the informative review. I'm thinking the cost is part of the inaccuracy. Something by a company with more invested in the tech may be more accurate as well. I'm using the Dexcom G7 and quite happy with it. The best part is that I can see my readings at a moment's notice. That really helps a lot in managing my condition.
I'm supper exited about the G7s minute by minute data access. I would have already made the jump, but I am waiting for omni5 compatability. Hopefully, very soon.
I hope one day to have one of those, to relieve my fingers, but in Guatemala that technology has not yet arrived.
The Dexcom is usually not that much off. Only sometimes it's more off.
The technology will still improve but to measure without lancing and then more or less any time is invaluable.
Seems like you should only have one watch on each wrist.
Yes
That's exactly I was wondering too. He is pointing to his wrist with two watches and says "this shows".
Which one? It's a poor show
It shouldn’t matter
I had a de con for a while. I found it to be highly inaccurate at times. Could never trust it so I stopped using it.
I agree. The light from each watch can interfere with the readings of the other as the light diffuses through the flesh. Unless you know the exact spectrums and the technology behind them you can’t know what it does to the readings.
Thanks for this information, it was really helpful. We bought a smart watch like this after being told that my husband was pre-diabetic and were wondering about the accuracy. Interesting test.
You’re very welcome.
Just a note about testing. I too have an Accu-Check meter and it can give me widely different numbers when I do checks. In fact in 5 tries it may not give me the same reading twice. Sometimes the results vary greatly when using a different finger to test from. I have checked with my doctors and registered the variance in results but they don't seem concerned. My point is that unless we see it give you the same result on multiple tests, we have no way to verify it isn't off though I agree, it's probably more trusted by doctors. I would have been interested in seeing how much variance there was in the watch with multiple readings. I managed several QA departments and on something like this we would do anywhere from a minimum of 3 tests to as many as 10 or more to determine accuracy of readings.
When I checked on how the watches worked, it seemed to indicate they worked off perspiration. If so, it may be useful to make sure the watch is in good contact with a specific portion of the skin during it's testing time. And to make sure it is in the same area of the wrist each time. In the video it didn't show how well it was in contact with your wrist and you were wearing the Dexcom along side it. That probably makes no difference but it may. In testing I wouldn't put the two next to each other as there is a small possibility one may interfere with the other.
That said, I have not seen any medical evaluation on the accuracy of the watches and would want to see an independent labs evaluation of the non intrusive way of measuring blood sugar. Obviously if it is getting it from perspiration then humidity and sweat would make a difference in the readings.
I hope you will teste newer watches as they become available and perhaps see if different models are more accurate than the $30 eBay / Amazon watch. Do they get better over time as the technology become more common.
Thanks for posting your review.
If you go to your doctor's office tomorrow, you will receive a different measurement as well. It all depends on what you ate the day before, how much you moved, how you slept, your stress level, etc.
The "accuracy" from glucose meters comes from long term observations.
@@krollpeter - I think I may not have been clear. I can take 15 readings all within minutes of each other on the Accu-Check meter and never test the same twice. The amount can vary greatly EVEN from the same blood drop. I can read from 106 to 148 doing several tests upon awakening all in rapid succession. To put it simply, I have yet to see a glucose tester that as an Electronics Engineer I believe gives you a reliable reading AT ALL. I have been looking for something more accurate. I am pretty sure the smart watches are total bunk but then I don't trust the Accu-Check meter either. If my Volt Ohm Meter gave me that range of results testing voltages or resistance, I would throw it out the window. But when I check with my doc as to why it's giving me such wide readings they tell me not to do so many tests. Just trust the number I get the first time. LOL Oh well. I will continue to look.
My point was only that I wouldn't trust that Accu-Check meter to give you an accurate enough reading in which to base the accuracy of the reading of the other two devices. Your experience with the Accu-Check may be different than mine but I find it more like a guessing game.
Hey, thanks for the quick reply.
Subscribing in hopes you will continue to test more meters.
Thanks for the informative comment. I definitely look forward to testing new devices as close to instruction as possible. I just need to find a creative way to pay for them all.
@@typ3meaccu check isn't accurate
If you read the manual then you will know it is only 95% accurate and this is the standard set by government. If you want an accurate reading you need to do it in the lab
Great job explaining new blood glucose watch I like it love to have one thanks
Good content.. Best review video on non invasive glucose monitoring.. looking forward for more informative content..
I'm type 1 diabetic since 18 years
I'm using freestyle libre 2
Thank you Husain.
I am testing an E420 and so far took a few hundred readings against the Libra. They are not as wild as yours, but certainly, there is a wide error margin that does not seem to be dependent on factors such as ambient temperature or anything else I could think of.
Testing with fewer readings against a Caresens N meter, I found that the correlation is a lot better.
I do get similar readings every day more or less regardless of what I do, but the Libra curve is very similar to the one on the watch, so that's to do with my medication and daily work patterns. I don't think the watch is making it up according to the time of day.
My watch certainly has some predictive value within the range of my BGL's, although it required calibration to deliver some kind of results. The manufacturer ignored my request for information, so I don't know whether the calibration is a fixed offset or an AI that requires repeated recalibration. I only used a fixed offset so far. I make out the error range to be +/- 2mmol/l, which is not bad for most purposes.
The physiology needs to be kept in mind. Arterial glucose is the gold standard, with capillary glucose (fingerprick) being almost identical. Venous glucose can be substantially lower, depending on what the tissue is doing.
Interstitial fluid glucose (which is what both CGM and the smartwatch measure) is not the same as capillary glucose, unless there is a steady state - prolonged rest and no change in BGL. IF glucose can be lower if the cells are busy sucking up energy, and it can be higher if they are quiescent. It turns out that all of this had been researched, and CGM errors are well-documented - unfortunately, the smartwatch manufacturers are completely silent about their data.
I have the Freestyle Libre 2 system. Very happy with it.
Thanks bro! I’m not diabetic but I’m pretty old and they are scaring me with all the info about glucose spikes and brain damage.
You're welcome. Stay vigilant, and remember you are your best advocate. 👌
Great review.. I`m T1 and Using Freestyle Libre 1 version. Thanks ¡
Hi there. Thank you very much for these tests ! Its what i fought, it just generates numbers inside the expected range
Hi Hurst. It's such a shame, I really wished it would have worked properly.
Nice Ty!! . . . YOU ~ ROCK ! !
I just discovered your channel, I use libre 2 and a contour meter. Mine have been pretty accurate so far. I’m skeptical about the watch even before your video only because it’s so new. Keep up the great work
Thanks, James. I really appreciate the encouragement.
Thanks for the informative review. Would love a non invasive way to check blood sugar level in the future if and when tech is perfected.
This will not be only for diabetics and also for non-diabetics who wants to monitor their health.
More Power to Your YT Channel.
Thanks, Sonny, I really appreciate your encouragement.
Their are people with a rare desease (GSD) who also have to monitor their blood sugar, so yes it's not only for diabetics.
Thank you so much for doing this!
You're welcome, Bertram.
When you did the glucometer reading, it looked like your finger was wet from the alcohol wipe. I have found that if my finger is wet it lowers the test results. The wetness I am seeing could be an artifact from the camera and lighting...
I am testing a ks02 and comparing results against a libre/miaomiao/xdrip. I am type 2 and dont get hypo. Since i am on a low carb diet my highs are around 150 or so. I set the watch for tracking continuously and i did get some interesting results. After having 3 meals i was able to see 3 peaks, and the levels were similar to those on the calibrated libre/xdrip. So far, i would not trust individual readings with the watch or expect any accuracy, but the cgm feature surprised me and will keep exploring it.
Thanks for sharing your insight, Horacio. You're smart to take a calculated approach with this tech. It's definitely proving to be unreliable.
if you would be fasting 24 hours you would also be seeing the fake meter displaying your 3 peaks. also if you would attach this watch to a dead cat, it would still be displaying 3 peaks daily and also provide you a miracle and show that the cat's corpse sill has pulse and blood pressure.
Good video, I am looking for something to use with my finger sticks, To give me an idea what my sugars are doing. Thanks.
I’ve not if not unusual to get different readings
I have 3 different glucose meters and test at the same thing always different results 😮
I'm not advocating for this to be a life saving device, however I did get some different readings by doing a couple adjustments with the F57L. (20+ points)
By adjusting the skin color and tightness of the band and no hair under the sensor, and inside wrist vs outside wrist! Take these readings and compare to other medical devices for baseline of accuracy maybe, also when I take glucose, heart rate, blood glucose etc I tighten one notch and I can feel my pulse under the watch. As far as sleeping and daily wear and it giving me patterns through the day I wear it snug but not tight. Just a thought for anyone who has one of these in lieu of $5-700 apple watch that gives same measurements relatively that I have seen with same degree of accuracy in comparison?
Great video! I have type 1 diabetes and been looking for an alternative to the glucose meter, thanks for the info.
Thanks Daniel 😊
Nice Comparison, Very usefull to make final opinion without confused.
Thank you, and you're welcome.
My highly PERSONAL experience with the E600 smartwatch for 3 weeks:
1. You must do at least 3 measurements to get a somewhat reliable result. The average is close to the value of the blood test.
2. Yes, as much as I can see, the graph looks the same every day, independently of what I do, when and what I eat. So the watch is just 'guessing' or has some kind of built in bias according to the time of the day. It DOES some measuring, but it's accuracy is very questionable.
Right! Thanks for the info. I'm glad I wasn't the only one
I agree, its accuracy is questionable. Its a gimmick.
My smartwatch gave me different
I bought thef57l and the glucose is way off.
Thanks for doing this testing, I've been looking for a review. I do finger sticks every morning but need something more often and don't like finger sticks.
Your very welcome
I would also question the accuracy of the Accu-Chek, unless you have calibrated it. They can be off. I use an Accu-Chek daily.
I use a Freestyle Libre 3 and check it with a Keto Mojo meter. They are fairly close. I also have a few different glucose watches and they are usually not accurate.
Thanks
Thank you for sharing the results of your experiment. Happy with my Dexcom G6 (besides the initial 12-24 hours after a sensor change). And no, I don't want the watch. You might be stuck with it. 😅
😆 I was afraid of that.
Interesting technology and you gave us a first look at it, at least for me. Seems there are a lot more variables with an external device that would come into play to contribute to its inaccuracy. Currently use Dexcom G6 with Tandem pump with control IQ and very satisfied. G6 does need some "tutoring" the first day but after that it is fine. The $30 price did not give me any warm fusses about the watch. I'll "stick" with what I am now using and looking forward to the G7 when it can talk to the pump. And a suggestion: I'm 73 and have hearing aids. That background music beat made it more difficult for me to understand you. Everyone would be able to understand you without the background music whereas others could find it distracting. So to please everyone . . . . And if selected for the watch, make another selection. If it doesn't work it is just a another paperweight. IMHO
Hello Dwight thank you so much for your comment I will definitely take your advice into consideration. I agree that the variables are numerous and just like most diabetics. For me, the most important thing to any technology is whether or not I can rely on it on a day to day basis.
Dwight...It is difficult to recognise value, given how we are being extremely ripped of by the sickess professionals. I also have developed senseneurial hearing problems (73 and a life long fitness consultant).
For instance, I heard from a audiologist insider, that h.aides cost about $ 70 .00 and are sold for up to $ 9 000....I use a couple of the watches (look at my replies above) ...just to keep track. Not diabetic, but like to keep my eyes open.
Such breakthroughs create equivalent to reactions to Tesla (the original ) by Edisons backers (JP Morgan bank....always the banks involved !!!)
I suggest you get one anyway. They are nice accurate time pieces regardless.
I have a "smart" watch glucose tester and always wonder about accuracy. Thank you for the information.
You're very welcome, Ellis
Thanks I didn't know this tech existed.
Hopefully it will get better over time.
Thanks for the great video! Very helpful. I'd like to try the watch if you want to give it to me. I use a blood glucose test strip. Loved how thorough and quick your explanation was for this tech.
Thanks, Mod Granny, I will be conducting the giveaway today and will definitely add your name in the bowl.
@@typ3me Thanks so much!
Thank you for the analysis. I use EYVA noninvasive device and readings are not comparable to Accucheck readings. I am using the device for more than 4 weeks and it is not even closet to AccuCheck.
It is very nice and helpful for me like diabetic people. Thanks for introducing this.
You're welcome George
I bought an Unvera watch which was made in China and it broke after 3 days of use. Good thing! Thanks for the information
Thank you for sharing.
We only use it in the morning. But our results are not that far off.
Thank you for making this video.
You're welcome 😊
Hopefully the accuracy will get better with future advancements.
A few things there you should do 2 to 3 for the Acu tester you can get differences depending on how much blood then average them and you should have the watch sit flat on your wrist . Saw almost every time it was being pushed up but the second watch you were wearing so I think it might not have been getting good contacts . Also like the first you should run the test for each device 2 to 3 times to have a good average . So I would want you to try again but do better testing as well . I also think that having the Non-Invasive Blood Glucose Watch higher on the arm might also make it harder to get a good reading as well . The wrist is a good point to test with very little in the way no fat or muscle in the way
Thanks for the advice. I do agree that in order to achieve better data all of these suggestions would help, However I also think it may be impractical to expect the average person to have to go through such a hassle in order to make sure the readings they are receiving are accurate. For this reason, I conducted the tests as an average user just trying to manage diabetes. Thanks again for the suggestion, and stay well.
I use nothing at all, except my medical blood test for my doctor, I had my a1c shoot up to 9.2 in December and I declined medication and immediately changed my diet to Keto with an 18/6 fasting routine and in 5 months lowered my a1c to 5.9 and still dropping, my blood glucose is now 95 down from 175, I have lost 25 pounds down from 191 and I feel better.
Thanks for the great review with other forms of reference, others who review these just guess if they are working, Good Job and thanks.
Thanks, Larry and FANTASTIC job on your health journey.
Can u send me info to your diet I'm a vegan so it's kinda work hard for me
@larry8749 your reply is quite interesting and capturing. I am keen to know your Keto diet and the quantities . How could I contact you.If you really feel like helping me.
CGMs and finger stick glucometers measure glucose concentration from different sources within the body. Freestyle Libre and Dexcom G6 are factory-calibrated to estimate blood glucose based on interstitial glucose - which is the fluid between skin cells. These numbers can lag behind capillary blood glucose levels (aka a finger stick readings) by ~15 minutes depending on how quickly things are changing. This can stack up especially during times of actively changing glucose to produce a delta between finger stick and CGM reading. If you're comparing readings, it's best to do so in a fasted state.
Thanks Michael, your comment is absolutely true. I consider these truths often during the production of this video and many of my videos
@@typ3me It took me a while wondering why the CGM was off but waiting I was equal most of the time unless I was checking a rapid change situation. Great info 👍
T2. I can run really low like in the 40s and there is no way I would use that watch. I appreciate you doing this test.
You’re very welcome Tammi.
Thanks for doing this. I figured it was too good to be true when I saw these for sale at under $100. Way to goo to be true.
Thanks Joe and you’re very welcome.
Interesting watching this video. I'm from Ireland I'm a type one diabetic for over 56 years and can say I'm pretty much well controlled I have just moved over to the Dexcom G7. I just bought the F57L smartwatch and like you I have been testing all three blood glucose meters. The test strip finger blood is always two points below the dexcom reading as you could expect as it's just skin reading and the F57L is always in the 6's regardless of the other readings which could be way above or below when I did the test. I was thinking of returning the F57L as it's not that smart at all. Also the H Band app does not record the Blood Glucose readings it's just a single reading from the watch that can be way off.
Thanks, Jackie. If you purchased the watch to help track your glucose numbers, I would definitely think about returning it also.
My name is Miguel Santos and I am currently using the Libre 2 system. Thank you for the information.
You're welcome, Miguel.
Thanks for this video. You saved me 30 bucks.
Good content, update us once you get any working device .
I'm using Hystorm smart health watch with glucose reading. I don't have a way to check to know if this watch is accurate or not. It reads every half hour and has a graph showing the range throughout the day.
I bought an E500 watch which is supposed to have the same feature. I didn't buy it for blood glucose monitoring, but since I did have an actual blood glucose tester at home I decided to test the accuracy. As far as I know the results are not related to actual blood glucose levels at all. The watch does show some up/down trends, but even those have no relation to real blood glucose levels whatsoever.
It seems to have a good O2 and body temperature sensor, it's good for tracking sleep quality, plus it has a pretty good feature that calculates you heartrate variability, basically telling you how exhausted you really are. But even the standard heartrate monitor doesn't really work over 115 bpm. My experience so far has been that the more features a chinese smartwatch has, the worse quality they are. It doesn't seem to be related to price as I also own a very simple one that only measures heartrate, sleep quality and o2 saturation on demand, it was very cheap and works with zero issues.
Thank you, Vozkaa, for your comment and in-depth feedback with this device. It's a shame that at the low price of just 30 bucks, we can't have an actual reliable device.
@@typ3me We don't have any actual reliable $30 insulin pumps either, and "all" they are basically is motorized syringes.
I am Type-2 and I almost purchased this. Thanks for the review.
You're very welcome
BEFORE YOU GIVE THE WATCH AWAY - please re-do the test again because i believe the watch did not give accurate reading due to operator's errors - in order to get a more accurate reading on the glucose watch, you need to let the watch rest on your wrist without movement, or preferably, you gently hold down the watch on your wrist until the watch has the sufficient time to give the reading. Those health watches also have blood pressure readings and body temperature readings as well as oxygen saturation readings - perhaps you can consider testing whether those features are accurate on the watch?
Hi Mike. Perhaps the watch you are using has different instructions. The instruction included on this one only says "#8. Blood Glucose: switch to the blood glucose interface click the Start button, and it will start to test your real-time blood glucose." I wish there was more but, that's it. If you have different instructions, please share the link and I'll be sure to share it with my viewers.
To me, it seemed that the test watch was awfully loose. The other watch seemed much tighter and in a better position to measure.
i agree. it looked like it was raised up on one side because it was too high up and competing for space with the other watch. the directions tell you to press it flat to your skin and he didn’t. i do own this watch and will do my own tests
great review. you save my money. I almost buy this device
Am using One Touch Select here in Cebu, Philippines. Thanks for this great product review. It's very informative
You're very welcome, and thank you for the encouragement.
I use the Kroger brand finger Stick to do glucose monitoring... would love to not have to stick so much. 9:54
I only need the ballpark: super low, low, normal, high, super high. The Daxcom seems to deliver, the smart watch was a disappoinment.
Great video!❤😊
Thanks, Ian.
This is really interesting. I hope this technology keeps improving. Finger sticks suck!!
I read another review that claimed Smartwatch technology for glucose hasn't arrived yet. The best results were from Bluetooth devices like the G6 or G7 displaying them on your watch. I was very curious how that very model would perform and you confirmed the articles findings. I think it says a lot when the major watch makers do not offer this feature yet.
Great point. I had hoped these watches were using a leaked technology with hopes to be first on the market. I now believe it's all hog wash.
There's a Facebook ad seeming to use part of what I think is this video to promote their watch.
Thanks for the info. I’ve reported it and am waiting for them to take down the illegal use and alteration of my content
From what I found is the watch app has you enter a range, then it assumes you eat at 6AM/12PM/6PM and tracks up and down based upon those assumptions.

Hello their, I am going to see myDr. Friday, pretty darn sure I have type 2 pre diabetes. Been on keto for one month and lost 11 pounds. Keep up the great explanation and experiment. Rose
Thank you, Rose . 11lbs is amazing 👏. At that rate, this whole diabetes thing will be behind you .
Using a KS02 watch, it has a personalize baseline calibration, still seeing how accurate it is, calibrate as fasting first thing but it still off sometimes by a lot. I’m still working out all the kinks…
Interesting, let me know how it goes.
Hi …. how do your watch working?
What’s the best to get …?
Apple have 1 soon…?
I got the f57l and I'll keep it for the other functions regardless (BP & SpO2 are close enough) - i tried just continually doing a few glucose tests in a row (literally seconds between), it gave me 6.06, 6.47, 6.54, 6.83, 6.72... that's a pretty wide variation. Without a finger jab test I have nothing to compare it to though.
Those variations are insane 😳
The smart watch guesses the glucose reading. That is my experience, so I don't rely on it for blood glucose reading. I use it for other reading like BP, O2 saturation, steps calculator, temperature, heart rate. I'm not so sure of the ECG, it's reading has to be compared.
Thank you for sharing. I'll have to try the other features as well
This watch tô make you feel good. Always good reading.
Hahaha! They should SUE the Maker of that garbage-watch for Medical Malpractice.
Right!
I concur with the report that is shown here. I suspect the same applies for all these China "smartmatches".
I tested the Aliexpress E400 Smartwatch. It's sold at Amazon as well. I compared the data against my Contour blood glucose monitor, which the FDA ranked highest in terms of accuracy. The data I found were vastly off, much identical to what you show here for the F57L.
After a few days I observed a pattern. I suspected the "results" being pre-programmed into the firmware of the watch.
I made a 75 g sugar blood sugar test, and that watch did not move at all. I then also tested the other function, such as heart rate, blood pressure, etc.. I tested against quality devices which are made for their purpose. On one day I even took the smart watch with me to the clinic for comparison to doctor's results. Everything was way off, even simple data such as heart rate. For example, it showed a heart rate around 70-80, when it should have shown something in between 150 and 180.
Do not buy these, unless you just want an electronic watch with a nice, colourful display only. Do not rely on them for health functions. There should be regulations in place for devices that claim health related functions.
Thank you, Peter, for sharing your experience. Great insight.
It would be nice if this tech improves some day. I use the G6. I'm currently moving in the direction of keto, and it's doing wonders for my sugars.
Congrats. Keep up the good work and stay healthy
Thank you for this accurate demo, it saved me $30 and lots of time, not to go for one.
You're very welcome ☺️
hi, thank you for your nice analysis of the accurate blood glucose measure and the smartwatches. I am a diabetic and still I need it to monitor my glucose level. Maybe, I have one question; how about the scientists or manufacturer company working on it to improve the accuracy of the Suga smartwatch?
Thank you. I haven't tested that one yet. I look forward to putting it to the test once it releases.
I already have the F57L, I find that it only gets accurate glucose readings when it is centered on your wrist and held down firmly (which is recommended in the instructions I received. The wrist band is annoying for me as I have very thick wrists and can only wear it on the very last hole on the band and it stretches out the longer you have the watch on causing the watch to slide to the side of your wrist rather than staying on top. You might want to try it again repositioning it on your wrist and holding more firmly down on your skin for each reading. Doing this I find it consistently reads about 10mg higher than a handheld meter from about 80mg to 220mg and lower than 80mg it reads about 20 higher, while over 220 it reads about 30-40 higher; this is consistent with a product that would rather be wrong ion a way that encourages users to double check with an actual glucometer (which is also recommended in the instructions).
Thanks for the advice. I tried this with the $130 model also HBand. Unfortunately It made no difference.
I just purchased the Suga Watch and want to know the calculation to get my blood glucose readings. Can you provide that ? Thank you
@@joancardinale4674 I also suggest using it side by side with a tradition glucometer for a least a week to see how consistently it works for you personally.
@joancardinale4674 Hi what is the “Sugar Watch” and what type of calculations do you need?
@@joancardinale4674 1 mmol/L equals approximately 18 mg/dL. Therefore, in order to convert from mmol/L to mg/dL, the blood glucose value needs to be multiplied by 18.0182. There are a number of online calculators that will do this conversion for you. Mmol is the standard measurement used in the UK and many countries that were former UK colonies.
I am using the Dexcom G6 although I will be migrating to the G7
Mine free style I see is off by 50 /30 off I got the test machine still so I see the difference so sometimes I don’t trust free style Libre that much I something my sugar jumps later my sugar drops back normal I was going to by the watch because it says it reads sugar levels thnxs I will stick with my machine picking my fingers I’m good thnxs for the review
I bought a glucose watch for my wife. She was and is going the Libra sensor, which does continuous glucose monitoring. It was not even close to the Libra reading. Gave the watch to our daughter as a toy!
😉Good idea. It can be an amazing toy, or an unreliable medical device.
Please check left and right hand with accu check.. Mybe different part of body have different levels reading.. Or you can make this for another videos..
Very interesting video. Even though I'm T1, I don't qualify for a CGM device here in the UK, so have to jab my fingers at least 3 times a day. A smart watch that uses light would be ideal but I know Apple have been testing this technology for years (quite literally), and if they can't yet get the accuracy they want, especially for medical certification, then some cheap $30 smart watch is definitely going to be a con.
Thanks, Mac. If you're a T1D, why is it so difficult to get approved for a CGM where you live? What are the road blocks and barriers you have to overcome.
@@typ3me I was diagnosed as T2D over two decades ago and immediately put on a cocktail of drugs (metformin and gliclazide but not insulin). Being 6ft tall, weighing in at just over 70Kgs and being a bit of a health nut I didn't fit the profile of a typical T2D patient and I didn't respond to the drugs. It took my doctor over a year of me having ccrazy high blood sugars to dig a bit deeper and they found from blood tests that I had auto-immune diabetes which had wiped out my pancreas. I was told I would be treated as though I was T1D and started on insulin, but that because I wasn't born with the disease, I didn't qualify as a 'true' T1D and thus couldn't have a CGM device or pump which T1Ds can get free on the UK National Health Service.
The video is great, my only fear is that since the watch uses light to do the reading, the position on the wrist is important and one of the watches is pretty hight up your wrist. That could be giving a wrong reading.
Thanks, Marcelo. I considered this when making the video. I read and followed the instructions from the watch booklet, then wore it according to specifications. It seems high to me also, but apparently, it reads poorly no matter where it's worn.
There is a flaw in the way the glucose meters were tested. I have tested my glucose within seconds of each other, and those tests have always been different, and the differences have always been pronounced. There is a reason for taking the A1C test because it measures glucose over 90 days.
T2 using finger prick. I appreciate the review. It seems the Suga Wolf Notch smart watch is not an accurate way to monitor your blood sugar. Thanks for answering my questions on whether to invest one one.
You're very welcome, Sandra.
Am T2 diet controlled on low carb diet... currently use Accu Chek meter... long for the day when an accurate implanted CGM is viable.
Accu check and 3 monthly Hb1ac is the only way - I wish we could have a watch that can do this😢
Thank you
You're welcome
The Dexcom is 15 minutes later than the Accu CHEK because it measures interstitial fluid and not your blood. It would have been more accurate to wait 15 minutes and then see what the Dexcom was reading. When going up or down, especially with straight up arrow, it's going to be off.
Thanks for the info, Teresa. My Dexcom G6 updates every 5 minutes. I thought about using your method to wait until it's most accurate, but I wanted to use Dexcoms 20 rule. Here is a link if you would like to read about it.
www.dexcom.com/en-us/faqs/is-my-dexcom-sensor-accurate
@@typ3me That's a 20% rule they say if it's out by more than 20% they replace it. it's also why they only want comparisons with steady sugar levels. The fluid lags the blood by 5 mins or so and the Dex takes some time to process and smooth the Dex latency is actually is 10-15 mins. With proper calibration my Dex is normally within 1-2% 2 updates after a finger stick test.
I bought one of these watches and tested it as was done here. My tests returned similar errors. I would caution anyone who is a diabetic or pre diabetic not to rely on thie sort of technology. I returned mine but had to pay 18 bucks for postage that was not refunded
It is nice to actually see some one test with other devices. Some one here just test the watch and say things like I feel it is acurate. I want to know if it is or not so glad you do other test with it. One thing I have found is that meters are not always accurate. I know I have two one the Doctor gave me that is 18% off and the other 9% off. I measure this with the A1C to see how much a difference tthere is with that. I know another thing is tht depending on where you have different deivces it will read the blood sugar differently so that might explain why te dexcon is off because it is reading it from another part of your body probably upper arm.
I agree that it is unfortunate that we can not expect any device to be dead on. That would just be wishful thinking. However, I do think it's important to use the BG meter and Dex as a reference since they are trusted devices. Thanks again for the comment and for supporting the channel.
Thanks for this video ,my niece has 1st diabetes,she is only 9 yrs😢
I'm sorry to hear that. I hope that she can find ways to manage and thrive with her condition.
That's a great review appreciated. Do you think Apple has got the correct tech for a legit watch like that?? I use the dexcom 6 and omnipod 5. With galaxy smart watch.
Seems to be the best they've come up with so far. I've only been using that system for a month or so and I'm still actively learning about it, but so far I'm very happy with it.
This is the first video of yours that I watched. It was good and interesting. I have a question (which you might have covered in a previous video) about why you use your Accu-Chek as ground-truth (at least that's what it seems.) I use and Accu-Chek Aviva myself and lots of readings have given me reason to question its accuracy. I get the feeling that BGM is like horseshoes and hand grenades: pinpoint accuracy isn't a real goal.
Hi, andhisband. Yes, the simple answer is that it is the only thing my insurance covers. As you know diabetes supplies get pricey. 🙃
Wow you put alot of effort
Thank you. 😊
Well i read somewhere that to check the glucose, the smartwatch should be warn on the internal side of the wrist.
I am waiting i chinese smartwatch that is meant to do it, and i will tell you if it's more accurate this way
I got one of the F57L devices. I was not able to use their app as it required Android version 4.4 which I do not have. So, I might not have gotten the latest firmware (if their app updates the firmware). I have taken many readings; but never achieved a reading below 6.0x nor above 6.9x. I also have not gotten it to reliably take the same measurement twice in a row. Even when I take three measurements in a row, they seem to just be random numbers in the 6.xx range. I have currently lost faith in mine until I can manage to get a firmware update .... then I will try again...
Regarding the G6 accuracy...There is a weird calibration procedure with the G6. If I go to the calibration portion of the G6 on my phone and input what my meter says it should be, it takes what it currently shows and then averages the two readings. OTOH, if I input the meter reading TWICE into the calibration screen, my phone will now match the meter.
So I wonder if I am supposed to calibrate it just once, or should I calibrate it twice so that the meter and the G6 are in agreement. What do you think?
Hi Moodberry, Unlike the G6 app this watch does not offer a collaboration option. So unfortunately nothing you can do will help it read more accurately.
The experiment worked to show the inaccuracies of the watch.
With that said, Any given test on the Accu-Chek may or may not have been more accurate than the Dexcom, given that the newest Dexcom devices have a MARD of 8.2%. MARD stands for "mean (or median) absolute relative difference". It's a parameter used to describe the analytical performance of CGM systems. According to the FDA, Accu-Chek readings are 95% accurate within 15% for all readings within the "usable" blood glucose range and 99% accurate within 20% for all readings within that usable range. The odds are high that any given test on the Accu-Chek would be a few percentage points more accurate, but there is no certainty outside of lab tests.
Also, it is worth taking into consideration the slight delay in how glucose measured in interstitial fluid compares to blood samples.
All true and great information. Thanks for your post and contribution to this conversation.
Thanks, I was about to buy one, tired of poking myself. Type 2
Hopefully, a reliable option will hit the market soon.
