The issue is that manufacturers are incentivized to focus on the number of functionalities instead of their accuracy. Not many people will test the accuracy, nor will they watch your reviews, but they will compare the functionalities instead.
Yep, that is also what the marketing focusses on, many functions. Actually better accuracy would be nice, but more important is consistency to detect health issues. Helps if anything is not as it always was. I had the idea to allow user input. If I have my own O2 sensor or a heart rate sensor, I can input this data a couple of times into the software of the watch, and it would re-adjust itself to the wearers condition. The watch could even suggest when to do that, so that different conditions would be covered better.
And the worst thing is so many of the tech influencers on TH-cam, those bigger channels, they totally gloss over the accuracy claims with half assed efforts at measuring anything at all, some dont even do any measurements but then go to claim the readings were accurate anyway like the viewers are supposed to just take their word for it right after they admit they got their hands on a review sample or a unit directly from the vendors.
The issue is coming from Chinese culture. More crap. Always more crap. At the opposite: Japan, Germany, Swiss, etc.. Minimalist but super accurate stuff are coming from them. Americans tend to be more and more on the Chinese culture side... Sadly. Korean and Taiwan seems to be in the middle. Sometimes very nice, sometimes very crappy.
These videos are priceless, putting companies at their place with their nonsense marketing bullshit. It's being quite revealing to see the self-declared market leaders (Garmin, Polar) performing quite bad compared to non sport oriented brands. Awesome work as usual Rob, huge thanks!
Garmin or Polar are sports oriented watches (ok, some by Garmin are not) and please tell me at least one brand that beats them is sports analytics? And as a Polar user and Fitbit experimenter I can say that sleep score for both of them are +/-3 every night. If it's more than 3 it's almost always because Fitbit gets wake up/going to bed times wrong and I have to adjust them according to Polar. And except for Apple, let's not talk about the accuracy of HR monitoring for the device that don't even let you connect external HR chest strap.
@@nomoshiti what polar watch do you use, and do you know if you can connect a chest strap to your polar watch or maybe connect a chest strap to the Samsung Galaxy watch 5 pro to improve accuracy readings?
First of all It would be so irritating to wear a watch all the time even during sleeping... Do physical exercise automatically you can get good sleep... You don't need a device for that.
The best review I have seen in smart watches!! In the SPO2 test, I was expecting to see the comparison graph comparing with other models like in other tests, though.
Great work as always! There's one thing I'd really like you to cover, that is the sleep tracking performance of smartwatches/bands when using a third-party algorithm, specifically SleepAsAndroid app for android. This would take away those mediocre proprietary algorithms from the equation an really show the potential of a device. Although it doesn't support every device, it does a good job paired with wearos devices, mibands, amazfit, and some others. I'd honestly love to see it being tested!
Me too, I've been using this one from some time and I need to admit that SleepAsAndroid shows different results that original Samsung sleep tracking app. I wonder which one is more accurate.
@thequantifiedscientist Wow! The most indepth review I have seen. However, all your tests are done with a pre-release unit. The official launch date of the watch 5 is August 26th, so you may be missing some firmware updates that they were planning on pushing out prior to the release date. Updates and software could potentially skew all your results, like battery life. It would be interesting to see the same in-depth review after the official release date to make sure that the unit has all the firmware updates as intended upon release.
This is a great review! Honestly, I wouldnt be too reliant on a smartwatch regarding my health, I'm pretty surprised that the watch 5 have a somewhat average performance and not completely crap. The real reason why I got the samsung watch 5 was to use the cohesive ecology of samsung since I already gave the s23 ultra, the buds and a samsung TV. it's super efficient imo!
Great overview. I'm impressed that you've been able to get ahold of one of these over the past 10 days. Great technical review as always buddy. Thanks so much for making it. 👍
Fell on the Galaxy Watch 4 trap, definitely not falling for it again... The features need to be more accurate by now. When are they going to have an answer for Apple's sensor accuracy? That's why your reviews are so important...
Hey man, the galaxy watch takes about 2 weeks to understand how you use your watch and dynamically changes it, w5 has a bigger battery and lasts 3 or 4 days (from experience) compared to w4 which is around 1 or 2. Please double check this
Enjoyed your review as usual @Rob. Sad to see that the results have actually dropped since the last test you did, was really looking forward to getting this watch for my fitness, but I guess I'll wait till your next video on this after a software update! Cheers!
I guess I'll wait for the GW6 to see if they can better battery life, HR accuracy, sleep stage tracking, and so on. Been saying that since the GW Active 2 or whatever it was called. I'm not holding out any hope. So maybe the GW7 might get it right? Thanks for the review! Great stuff.
Great video as usual! I wish If you could start testing the other health features like the ECG, heart monitoring and maybe even the body composition, ... many smart watches test these things now, and Withings has many products that test these things also.
Great data review as always - love watching your videos. Was wondering if you also changed the settings on the watch to reflect the arm the watch was on when switching arms. By default I believe the orientation setting is set to the left arm and I'm wondering if changing it to the right would improve the step count reading accuracy of the right arm. Maybe worth trying out on your future review of the Watch 5.
Another great Scientific review, Rob. A sugestion could be reviews of Smart Scales: Those who uses bioimpedance. The Mi Scale 2 could be the first to be reviewed :)
Hi, very good review as always!👍🏼 You mentioned a second test of the Samsung Watch 4. Could you do a second test with the Garmin Epix 2 as well? This is a really expensive sports watch and was tested right when it came out. Results have been worse in comparison to the Samsung Watch 4 (which costs much less). It would be interesting to see if software updates improved the heart rate measurements. Many thanks!
Darn... I ordered the GW5Pro. I should've kept my money. Lol. All I can do is hope for Samsung to come up with a new update that will fix all these inaccurate results/testing. Doesnt have to be perfect. But at least have testing accuracy close to other sports watch. Thank you for this review. Samsung need to watch this video and make improvement asap before it goes out to consumer.
I absolutely love your research. I'm so frustrated because you have to shut down all of the sensors just to preserve the battery. What's the use of a watch if you can't use the sensors. Please evaluate the battery more! This is critical. 40mm vs the 44mm. I have the 40mm, the smaller battery is critical on how long it will last. Thanks!
Thank you for your review! You have saved me trading my galaxy classic watch 4 for this new watch 5. It is disappointing that it is not an improvement. I guess I will just stick with my watch 4 classic and utilise a polar H10 strap and run Google fit alongside Samsung Health....my search for one watch that is accurate and does all is still ongoing!
Hi Rob, you never waste my time 👌 Always very helpful and sometimes just disappointing, not you, but watch you're testing. what to do now? Galaxy or Venu 2 plus
Thank you for this. I am very disappointed as "I was" considering the Watch 5... now I am looking elsewhere checking your other reviews which are the only scientific analysis I have found. BUT.. ALSO... could you in your future test include swimming as an exercise for the heart tracking. Your work is credible and outstanding.
I know the advertising will show people swimming, but water damage will void your warranty even if its from swimming. Swim at your own risk fellas. All it takes is the smallest imperceivable crack to lower the water resistance of the watch.
Rob, I am kind of disappointed that you didn’t include blood pressure and body composition tests in your complete review of Galaxy Watch 5. I think you didn’t include those tests not because you can’t make an analysis on them but because other devices don’t offer these features. But it is not Samsung’s fault to have these features and lead the way. I believe others will follow Samsung and add these features in the near future. I wouldn’t conclude my opinion on Galaxy Watch 5’s health capabilities without seeing how well it performs in blood pressure and body composition measurements. It is also weird that you haven’t come up with a nice idea to do ECG tests as it is a feature offered by many watches now. At the very least, if you have access to raw ECG data, it is possible to do HRV test. Or it should be possible to input the raw ECG data to existing programs and output some cardiac parameters. I am also disappointed by the battery life of Watch 5. All the best.
The battery could be due to the fact it takes some time for samsung watches to optimize the battery for your use, I am going to guess that you had been using the galaxy watch 4 before the tests? Or did you reset them both?
Great review as always! Is there a reason most watch don't work very well at tracking heart rate during weight lifting compare to other fitness exercises? Would doing squad only improve the accuracy?
I'd certainly agree that when this watch is tracking the heart rate, it is pretty accurate. I bought mine end of Dec 2022, and it was doing a perfect job for about a month, then end of Jan/beg Feb it started to not track the increase of heart rate after the start of an exercise. This sometimes happened up to a third or more of the way through the workout. Once it tracked it was perfect to the end of the workout. But despite having it at Samsung Repair twice now, with parts replaced, it appears even worse, even when reset back to Nov 2022 firmware by Samsung. Now I see I'm not the only one complaining about workout tracking HR. So today I bought a Polar H10 chest strap instead for the workouts. Although many do report this issue, not everyone has the issue, but it is worth noting in case others also have this problem. Other functions and normal; resting HR etc all seem to work fine though.
@@i0sandman0i I'm using the Polar app itself, and it syncs to Strava, which Samsung Health reads data from. So my exercises are still showing inside Samsung Health. Sounds long, but Polar to Strava is just about instant, and Samsung Health takes an hour or two to show the exercise (all automatic tho).
@@i0sandman0i you'll be happy with it. It is very accurate, connects to quite a few things, and I even found an app for my Galaxy Watch that will connect directly to the strap and show the live reading. I don't wash mine in the washing machine tho like some people recommend - I just rinse under the tap and hang it up to dry.
This kind of devices always improve with software updates so the tests made in this video probably won't be the same in 2 months (because the watch has been released a few weeks) it would be interesting if you do the same tests months later to see if there was any improvement with the updates. Also it would be nice that you use more your social media, they're all abandoned
Maybe.. the Galaxy watch 4 was a pretty large upgrade over the 3, new os, new sensor suite, new SoC, etc.. you'd expect updates to drastically improve that. This watch isn't as much of an upgrade. Same SoC, mostly the same sensors, incremental OS. I don't think updates are going to have a significant effect here.
Hi! Yes, I will do an update a couple of months in, similar to what I did for the Watch4. And yes, I will start using social media again, I just need to figure out a way to make it fit in my full schedule ;-). Have a great day 😊
Samsung is a big company they should get it right from the first time, they have plenty of experience too. Check Apple they get it immediately right. There is no excuse for Samsug.
I have the Mi Band 7. Despite the appearance it's clear why it's a 'cheaper' device. It's disappointing in most ways as a smart wearable. Notifications are limited in how much they show, battery performance is quite poor, software support is awful with only a small handful of watch faces etc. Amazfit watches are a league above in the budget bracket.
Some of the positives/negatives may be due to the apps/software algorithms (which are the same/similar) rather than the hardware. So the results may improve as they work out the bugs, but new hardware may not be the answer. I am also surprised at your battery tests, not so much that the 4 performed better than the 5...but that the 4 performed well at all. There is not a single review of the 4 that was able to achieve more than 1 day per charge, but you seem to have outperformed this.
Sir i have a query! Huawei watch gt3 has a better heartrate senson trueseen5+ While huawei watch fit 2 has trueseen 4 But the results of the huawei watch fit are more accurate. Why is that? And if its the software then if the huawei gt3 is updated will it be a better option to buy?
Many thanks for the review, very detailed as usual! Do you think the Watch 5 has had any big improvements by now (in terms of accuracy), with more software updates? Or would you say it's still similar?
As always amazing reviews. Could you please let us know if the watch has a smart alarm feature and if the sleep tracking is accurate enough for this feature to actually work? Keep it up! Excellent review!
Very interesting and useful video, though I am not quite sure about your assessment on the measurements on GPS accuracy. I sail and have two Garmin GPS devices (one of them being the Garmin 78) and several navigation programs (apps) installed on my tablet and cell-phone to assist me while doing my navigation through the waters. Any of those are continuously informing the GPS positioning inaccuracy, which might very commonly vary from nothing up to plus-minus 25 meters deviation/inaccuracy (even when more than three satellites might be being used to set a position). The error/inaccuracy tends to be jumpy and not constant. Now let’s imagine that when you were cycling one day, at a given location there was a 20 meters error on determining your position and lets say it happened to be to the right of your path, and then the next day, there was for the same location a 20 meters deviation to the left. That could (could it?) determine a 40 meters difference of the specific location drawn for the path (track) from one day to the other (but that could have happened even if a Garmin specialized GPS was used to do the tracking). I am not saying that the watch’s GPS is or is not good enough (I don´t know and probably is not perfect), I am just saying that I think (though might be wrong) that your measurements in this regard might not be taking into account (might be overlooking) a variable or perhaps are missing an efficiency comparison with other GPS devices (as you certainly did for other covered aspects of the watch). (sorry for my English, as it is not my native language).
It's sad that companies try to convince people with health issues it's safe to switch to these watches to keep track of things. When they aren't very accurate.
I remember when I first got the watch 3 it used to stay for two days, then after an update it wouldn't even last a day, and later back to 2 days after yet another update. Could be a software thing that could be fixed later for the watch 5.
Hi! I really like the videos. If you would take a suggestion, please rank between devices by some metric like, mean square error of the benchmark. Each video compares a device to a benchmark. But, the videos do not compare them across different devices or different generations of the same devise. By ranking devices by metrics like mean square error, we can see which are the best devices for the things we care about, see them evolve each year, and push manufacturers to improve. I am also curious about which device do you actually use! 😀
Regarding extra awake time. I already mentioned this, but samsung states awake time also include moments when you change position, so it's not necessarily "awake" time, but rather movement detected by the watch. However, this monitoring seems to be worse than what I had with my watch4 lol
Hi, I really love your videos and appreciate the work you put in them. One suggestion from myself is maybe compare it against the watch that it replaces (in this case, it will be the GW4). I know you have the graph comparing it but GW4 have received quite a few updates since then so would like to see how how the GW5 fairs against GW4 running on the latest. Also, any way of testing the ECG and/or body composition? Thanks.
Thank you for this test and especially the SP02 section! I find my GW5 is also lower and shows 94% most of the time 😳... Can you test the Galaxy Fit 3 SP02 please 🙏
I also do weight lifting, not with the watch 5 but the watch 4. I tried to analyse if its able to pick up the increase in heart rate during sets, and it does not have problems doing this. But i also don't doubt that you are wearing the watch correctly. It might be a bit misleading that in your particulair case its not able to pick up the heart rate during lifting correctly, but for others it might be able to. it would be interesting to test this with another person, possibly different posture aswel.
Thanks for you detailed worked which is really inspiring. I have one request to you for analysis on watch 5 : could you please do review on sleep stages and corresponding heart rate changes
Just curious, but what do you do with all the watches you purchase? Guessing the reviews more than pay for themselves. Keep it up, you're doing a fantastic job.
I noticed that on the Samsung Healths app, if you look into sleep it generates data information for you along with the sleep cycles. Though the Watch5 still has a lot of awake time.
This is helpful information only you do. However it doesn't change my mind I'm sticking with galaxy watch 5 over huwawei lol due to a few reasons: -Galaxy watch has more 3rd party app -Its on sale on samssung site -It allows to message and text back with letting me know I sent the msg -I can watch some videos on it -I have a Galaxy phone
Hi. Nice evaluation of bells and whistles. However, it seems comparisons to any other consumer monitor, in this case the polar monitor is always open to any possible weaknesses in the reference. You should introduce this video with a quick bit of discussion where you compare the polar to medical grade devices. If this was a scientific paper under review this point would cause me to ask for "major revisions" and a second review. But nice info and useful place to start. Maybe samsung will make some software improvement as the device is in operation. But again, its difficult to fully evaluate a device vs. another consumer device.
I want to give Rob a shout-out about this review. This is the most informative video I have seen on the Samsung Watch 5. Also, it changes my decision not to buy it. I am looking for an accurate smartwatch to measure my blood pressure and workout heart rate. I wonder if anyone can offer their unbiased opinion as to which ones are the best?

I bought mine end of Dec 2022, and it was doing a perfect job for about a month, then end of Jan/beg Feb it started to not track the increase of heart rate after the start of an exercise. This sometimes happened up to a third or more of the way through the workout. Once it tracked it was perfect to the end of the workout. But despite having it at Samsung Repair twice now, with parts replaced, it appears even worse, even when reset back to Nov 2022 firmware by Samsung. Now I see I'm not the only one complaining about workout tracking HR. So today I bought a Polar H10 chest strap instead for the workouts. Although many do report this issue, not everyone has the issue, but it is worth noting in case others also have this problem. Other functions and normal; resting HR etc all seem to work fine though.
What are you connecting the strap to?
@@i0sandman0i I'm using the Polar app itself, and it syncs to Strava, which Samsung Health reads data from. So my exercises are still showing inside Samsung Health. Sounds long, but Polar to Strava is just about instant, and Samsung Health takes an hour or two to show the exercise (all automatic tho).
@@GadgeteerZA cool. Thanks. Ordered one now. I have a Garmin strap but you need a Garmin watch for it to work
@@i0sandman0i you'll be happy with it. It is very accurate, connects to quite a few things, and I even found an app for my Galaxy Watch that will connect directly to the strap and show the live reading. I don't wash mine in the washing machine tho like some people recommend - I just rinse under the tap and hang it up to dry.
This kind of devices always improve with software updates so the tests made in this video probably won't be the same in 2 months (because the watch has been released a few weeks) it would be interesting if you do the same tests months later to see if there was any improvement with the updates.
Also it would be nice that you use more your social media, they're all abandoned
Maybe.. the Galaxy watch 4 was a pretty large upgrade over the 3, new os, new sensor suite, new SoC, etc.. you'd expect updates to drastically improve that. This watch isn't as much of an upgrade. Same SoC, mostly the same sensors, incremental OS. I don't think updates are going to have a significant effect here.
Hi! Yes, I will do an update a couple of months in, similar to what I did for the Watch4. And yes, I will start using social media again, I just need to figure out a way to make it fit in my full schedule ;-). Have a great day 😊
Samsung is a big company they should get it right from the first time, they have plenty of experience too. Check Apple they get it immediately right. There is no excuse for Samsug.
@@TheQuantifiedScientist if I was you I wouldn't waste my time but it is up to you. Thank you for your efforts
improvement never happened with galaxy 4, samsung should be ashamed of the inaccuracy
Love your reviews, the only full in depth reviews out there. Mi Band 7 Pro next? 🔥
I have the Mi Band 7. Despite the appearance it's clear why it's a 'cheaper' device. It's disappointing in most ways as a smart wearable. Notifications are limited in how much they show, battery performance is quite poor, software support is awful with only a small handful of watch faces etc. Amazfit watches are a league above in the budget bracket.
Some of the positives/negatives may be due to the apps/software algorithms (which are the same/similar) rather than the hardware. So the results may improve as they work out the bugs, but new hardware may not be the answer.
I am also surprised at your battery tests, not so much that the 4 performed better than the 5...but that the 4 performed well at all. There is not a single review of the 4 that was able to achieve more than 1 day per charge, but you seem to have outperformed this.
Thanks for your testing ! You help many of us.
Sir i have a query!
Huawei watch gt3 has a better heartrate senson trueseen5+
While huawei watch fit 2 has trueseen 4
But the results of the huawei watch fit are more accurate. Why is that?
And if its the software then if the huawei gt3 is updated will it be a better option to buy?
Many thanks for the review, very detailed as usual! Do you think the Watch 5 has had any big improvements by now (in terms of accuracy), with more software updates? Or would you say it's still similar?
What a great analisys and vídeo, thank you so much
As always amazing reviews. Could you please let us know if the watch has a smart alarm feature and if the sleep tracking is accurate enough for this feature to actually work? Keep it up! Excellent review!
Hi! The fact that the sleep stage tracking is not very good makes me think that the smart alarm will not work so well😊
Very interesting and useful video, though I am not quite sure about your assessment on the measurements on GPS accuracy. I sail and have two Garmin GPS devices (one of them being the Garmin 78) and several navigation programs (apps) installed on my tablet and cell-phone to assist me while doing my navigation through the waters. Any of those are continuously informing the GPS positioning inaccuracy, which might very commonly vary from nothing up to plus-minus 25 meters deviation/inaccuracy (even when more than three satellites might be being used to set a position). The error/inaccuracy tends to be jumpy and not constant. Now let’s imagine that when you were cycling one day, at a given location there was a 20 meters error on determining your position and lets say it happened to be to the right of your path, and then the next day, there was for the same location a 20 meters deviation to the left. That could (could it?) determine a 40 meters difference of the specific location drawn for the path (track) from one day to the other (but that could have happened even if a Garmin specialized GPS was used to do the tracking). I am not saying that the watch’s GPS is or is not good enough (I don´t know and probably is not perfect), I am just saying that I think (though might be wrong) that your measurements in this regard might not be taking into account (might be overlooking) a variable or perhaps are missing an efficiency comparison with other GPS devices (as you certainly did for other covered aspects of the watch). (sorry for my English, as it is not my native language).
It's sad that companies try to convince people with health issues it's safe to switch to these watches to keep track of things.
When they aren't very accurate.
I'm surprised by the battery drain test. My Watch5 has noticeably better battery life compared to the watch4
I'm using the Galaxy Watch 4 classic and I can't wait for your GW4 update and comparison to GW5.
I remember when I first got the watch 3 it used to stay for two days, then after an update it wouldn't even last a day, and later back to 2 days after yet another update. Could be a software thing that could be fixed later for the watch 5.
Hi! Yes, lets see. I think more testing is needed for sure😊
Do the Mi Band 7 please
I am one complete scientific review away from buying it!
He did it already
Hi! I really like the videos. If you would take a suggestion, please rank between devices by some metric like, mean square error of the benchmark. Each video compares a device to a benchmark. But, the videos do not compare them across different devices or different generations of the same devise. By ranking devices by metrics like mean square error, we can see which are the best devices for the things we care about, see them evolve each year, and push manufacturers to improve. I am also curious about which device do you actually use! 😀
Regarding extra awake time. I already mentioned this, but samsung states awake time also include moments when you change position, so it's not necessarily "awake" time, but rather movement detected by the watch. However, this monitoring seems to be worse than what I had with my watch4 lol
Waiting review for galaxy watch 6! Big and small version.
Thx man. Best review on youtube!
Hi, I really love your videos and appreciate the work you put in them. One suggestion from myself is maybe compare it against the watch that it replaces (in this case, it will be the GW4). I know you have the graph comparing it but GW4 have received quite a few updates since then so would like to see how how the GW5 fairs against GW4 running on the latest. Also, any way of testing the ECG and/or body composition? Thanks.
I'd also be interested in the body composition testing. I'm consistently measuring ~10% higher body fat than my home scale and tester at the gym.
great work i almost watch all your reviews. are you planning to do any review for the xiaomi mi band 7 pro? seems like a great value device too!
would you do a test to check if the fitness tracking features work better if the watch is worn on the inside of the hand?
thanks for the test
Thanks for watching as always James!!
Sir,will any 'mi band 7 pro' review come in your channel??
Thanks for the great review. What about ECG measurements ?
he didn't do BIA either... I'm so confused why we got gps tracking review but not biometrics..?
Very keen to see you revisit the GW4!
As usaul you are BRILLIANT.
Awesome video. I appreciate all the time and expenses that you go through to bring these videos to us. Respect Sir
Still waiting for your huawei band 8 test video,good job
Great review! Looking forward to your future movies as Dr. Strange or Sherlock Holmes.
What about the BIA sensor? Any data on that?
Loved the video
Thank you for this test and especially the SP02 section! I find my GW5 is also lower and shows 94% most of the time 😳... Can you test the Galaxy Fit 3 SP02 please 🙏
How is heart rate tracking accuracy for resting heart rate or heart rate during sleep?
Amazing, thanks for these!
Cool video 😊
The sleep testing was so unfair for the watch lmao. 😂
I also do weight lifting, not with the watch 5 but the watch 4. I tried to analyse if its able to pick up the increase in heart rate during sets, and it does not have problems doing this. But i also don't doubt that you are wearing the watch correctly.
It might be a bit misleading that in your particulair case its not able to pick up the heart rate during lifting correctly, but for others it might be able to. it would be interesting to test this with another person, possibly different posture aswel.
Waited for this one! Thx
Hi Rob, I would love if you'd talk about the bio-impedic composition sensors. How does the watch perform relative to dedicated instruments?
Thanks for you detailed worked which is really inspiring. I have one request to you for analysis on watch 5 : could you please do review on sleep stages and corresponding heart rate changes
Just curious, but what do you do with all the watches you purchase? Guessing the reviews more than pay for themselves. Keep it up, you're doing a fantastic job.
Yes indeed
I noticed that on the Samsung Healths app, if you look into sleep it generates data information for you along with the sleep cycles. Though the Watch5 still has a lot of awake time.
Really like your realistic reviews. Please do a review on the Amazfit GTS 4 mini.
Amazfit t-rex 2 please! Especially dual band gps system accuracy. Thank you! Keep up great details content!
This is helpful information only you do. However it doesn't change my mind I'm sticking with galaxy watch 5 over huwawei lol due to a few reasons:
-Galaxy watch has more 3rd party app
-Its on sale on samssung site
-It allows to message and text back with letting me know I sent the msg
-I can watch some videos on it
-I have a Galaxy phone
I think I'm feeling a huge Apple vibe from this channel.
Hi. Nice evaluation of bells and whistles. However, it seems comparisons to any other consumer monitor, in this case the polar monitor is always open to any possible weaknesses in the reference. You should introduce this video with a quick bit of discussion where you compare the polar to medical grade devices. If this was a scientific paper under review this point would cause me to ask for "major revisions" and a second review. But nice info and useful place to start. Maybe samsung will make some software improvement as the device is in operation. But again, its difficult to fully evaluate a device vs. another consumer device.
Where can I see the rank/graph of watches precision shown on the video? Great review btw!
Time stamps are 🐐ed.
Awesome video. Are you going to test the watch 5 pro?
Great review! Thank you!
I want to give Rob a shout-out about this review. This is the most informative video I have seen on the Samsung Watch 5. Also, it changes my decision not to buy it. I am looking for an accurate smartwatch to measure my blood pressure and workout heart rate. I wonder if anyone can offer their unbiased opinion as to which ones are the best?
I would love you to test the pro to see if the pro has a superior software entwined within it.
Just NO
Great content
Thanks for being a loyal supporter!
