Ich komme aus Deutschland und finde deine Videos echt toll, weil man mal ein paar Informationen über die Genauigkeit der Produkte kriegt z. B. wollte ich mir einen Oura Ring 2 kaufen habe das aber dann wegen den Videos nicht gemacht da mir die Genauigkeit für diesen preis viel zu niedrig ist, würde mich echt freuen, wenn du mal die Genauigkeit des Xiaomi Band 4 oder 5 oder 3 testen könntest da dieses Gerät im Vergleich zum Oura Ring oder Fitbit zwischen 3 bis 10 mal günstiger ist. Ich danke dir für diese Videos und mach weiter damit falls du Zeit hast, es gibt echt viel Nachfrage für solche genauen und präzisen Videos wie deine!
Vielen Dank für das Kompliment! Ich habe möglicherweise einige Daten zum Mi Band 3, die ich überprüfen muss. Das Problem ist, dass das Abrufen der Rohdaten für diese Geräte manchmal schwierig ist. Aber ich habe definitiv auch vor, einige der "billigeren" Geräte zu überprüfen. Ich habe die Schrittzählung für das Mi Band 3 überprüft: th-cam.com/video/-T2xvWq5e3o/w-d-xo.html . Have a great day!
Great review! I was looking at the Oura ring and the Polar but decided to go with heartmath’s inner balance. It should be arriving in a few days. Apparently they have been around for some time and have a huge list of professional clients. It would be pretty cool to see how it holds out in your lab. Will you be comparing other biofeedback devices such as the Sensate Pebble as well as brain wave scanners like muse 2 or muse S with other similar devices? Wonderful channel. I feel as if it’s the only one I can trust on the subject.
Hi Michael! I had not heard of a lot of these yet :-D. I'll check them out on the internet and see if I can acquire some over time! Thanks so much for the suggestions !
Hey Rob! Thank"s for a truly great video. I am a PhD candidate in Belgrade working on HRV and EEG and I am interested if you could tell me what app did you use to record HRV from Polar chest strap during the night? It would really help my research!
Great videos! one tiny thing, the Polar is not considered as medical ground truth for ECG, you should really get a medical ECG device for such comparisons. Please continue with more videos! :)
Hi Fezzik! Of course you are right :-). But for these purposes I think the Polar was good enough, especially since the results matched so well. Have a wonderful day!!
Danke für das Video, ich habe schon festgestellt, dass mir Werte fehlen, wenn meine Finger zu sehr angeschwollen sind in der Nacht. Deshalb nutze ich den Ring hauptsächlich links.
Hi! Thanks for the compliment :-) . I am actually quite happy with my views at this point already, hopefully I can continue to grow and improve my videos :-D. Have a great day!
Hi! I plan to make some videos about the Whoop strap! However, the next videos I will first focus on the Apple Watch and the Fitbit Sense :-) . Stay tuned!
Hi! So I use the Oura ring and a FitbIt Charge 4 continuously. I also have some more custom devices, like a device that measures my light exposure and one for environmental temperature. I used the Spire Stone for a few years, but the charger broke, and they do not produce them any more... I track my home cycling with the Tacx Neo 2 Smart trainer.
I was fairly certain that heart rate increases when inhaling and decreases when exhaling, which is why longer exhales than inhales can calm people down. This is the opposite of what is said in the video? Am I wrong in my assumptions?
Hi Rob (awesome name ;-) ) ! I am planning to look into it, though I don't know the timeline yet. Recently a scientific paper came out about the Whoop strap and its sleep prediction, unfortunately I cannot access it, since it is locked behind a pay-wall. Hopefully I can get to it at some point and also test it myself. Stay tuned!
@@TheQuantifiedScientist I found the article via Sci-Hub. The lead author's position at the uni is sponsored by Whoop. Like the oura ring, looks like it also fails to record data reliably, but I will leave interpretation and validation of results to you as I'm just an interested layman.
I've seen 3/4 videos and I have to say: finally some calculations about the performance of these devices, and great videos too🔝 I have a curiosity about the heart rate sensor: is it good the one incorporated by Fitbit, Xiaomi Mi Band and in general the fitness bands? Is at least somewhat accurate the heart rate number they give?
Wow, thanks Luigi! So, in my experience most of them are decent at tracking HR, though some tend to have some bias. I have not quantified this (yet), but my FitBit seems to be a bit low sometimes. However, the technology behind measuring HR on the wrist is quite advanced by now, so most will at least give a good indication. Though there will be some bad apples in there, so if you are looking for a specific device, generally a well established brand is a safer choice I would think. Anyhow, these are just my first thoughts, hope it answers your question!
@@TheQuantifiedScientist Thanks for the informations, man😉 It would be really cool if you would be able to quantify something like the Mi band 4/5, which are by far the most bought wearable in the world, but the Fitbit would be ok too, I think they're quite similar even if the price range is somewhat different. Oh, of course you have a new subscriber, I'm currently doing my specialization in statistics but for economics, and watching a "mad scientist" like you who measured the self-reported stress for 3 years straight is awesome ahah, great stuff!
Great quality video my brother. I am looking at the Oura ring for HRv and sleep monitoring, but I read some research that raised serious questions about the veracity of the sleep data that Oura ring provides. Have you seen this research? If so, be great to hear what you thought of it, thanks :)
I just found your channel because of the oura ring vs. EEG video and i love your channel! I'm trying to figure out if i will buy the oura ring or the galaxy watch 3. Will you test galaxy watch3? Or have you looked at it? Greetings from northern germany :)
Hi Niklas, unfortunately I have no experience with the galaxy watch. If you want to track your general health, I think the Oura ring is pretty good, but for sleep tracking it is not the best. What are you looking for?
@@TheQuantifiedScientist thanks for the answer! I'm looking for something to track general health + especially things like blood pressure, blood oxygen and pulse. The Galaxy watch3 seems like a good device for that + it'll get an EKG. I already ordered it and will compare the results with medical devices (my uncle is a doctor). If you want to, I could send you my results in a few weeks!
Great video and data! I believe some of the missing data may have been from the fit of your ring. It looked slightly loose which can cause inconsistencies in the readings, especially during movements during sleep.
get a pro grade microphone and crank the science part up to 11 and become a professional tech reviewer. you definitely have an edge on most other people I know.
Agree,, but remember,, that there's possibly just as many people who are not as tech savvy. I think your sound was great the way it was. Your clear and easy to understand, thanks for your reviews. Just subscribed 😃👍
Great review. Would be great to do the same for Whoop. One irrelevant observation; bit odd how your HR takes hours to go down (& HRV to go up). Do you eat or exercise really late??
Dr Great video. Now one question is most of Smart watches which has ECG measuring function only pdetects Heart Rate variability and also for this, the user has to put one of his Finger on top. Of smart watches or on top. Electrode to close the cycle and get a ECG/ Heart rate variability on demand. Ie user has to do manually each time to get Heart rate variability and ECG But on Oura Ring and also on Polar 10 Patch, how cone a continuous Heart Rate variability is obtained without using 3rd electrode n that too without keeping a finger on it?. Is the Tech used in Oura Ring and Ploar 10 is totally different from other smart watches tech used including Apple watches and Samsung galaxy watch? I kindly request you to give me a detailed reply sir on this tech used Life from. INDIA Thanks n regards
Hi, appreciate your thoughts on the Samsung Galaxy active watch, am waiting for their EKG app (for NZ) but understand is now available in the US. Great work. Regards Mike
Incredible review! I enjoyed the more objective perspective of the oura ring! Especially combined with your video on the accuracy of the oura ring’s sleep stage prediction. Thanks for your work!
Great video. I’ve been wondering why the resting heart rate of my own Oura gen2 always is about 10 lower than the resting heart of my Fitbit Sense watch. Based on your research, it sounds like it’s my Fitbit which is not showing accurate heart rate. Or then it’s just measured somehow differently, I haven’t looked into it in detail.
Hi Rob, can you please explain the difference between HRV and arrhythmia. Although I believe in the scientific findings, I find it hard to understand why high variability is good? I thought high variability would be the same as arrhythmia. But apparently not?
Hi Azat, I would need to dig into this a bit deeper to give a comprehensive answer, but I expect it all has to do with the underlying cause of the HRV. Normal HRV "is controlled by a primitive part of the nervous system called the autonomic nervous system (ANS). It works regardless of our desire and regulates, among other things, our heart rate, blood pressure, breathing, and digestion.". (www.health.harvard.edu/blog/heart-rate-variability-new-way-track-well-2017112212789 ). From what I understand arrhythmia is "due to problems with the electrical conduction system of the heart." (wikipedia), and it can also go hand in hand with abnormal heart rhythms (so the way the heart beats) . However, in tracking HRV, it might be that I cannot easily distinguish between the "good" HRV and arrhythmia. Both cause variation in the time between heart-beats, but the underlying cause is different. I am not a doctor or a HRV expert, but this is my best understanding. I would have to take some time to read more about it to give you a better answer. Hope this helps though! Have a great day!
May I ask what software did you use to take the HRV measurements? As far as I know, there are some apps out there such as Elite HRV but I am not sure how accurate they are.
Great video! Do you know any wearable (strap with ecg or somethings like that) which can be used to get ECG 24/7 with good resolution (to process raw data for HRV analysis etc) and can work offline for a few days and then sync to phone/cloud over BLE and then export raw ecg data? Right now i'm using polar h10 with Elite HRV, but there is few problems - the hrv app sometimes restarted and loses recordings, and the most thing to worry with polar is permanentl bluetooth signal emmitting near my hearth and that can be dangeroues for health. So i'm looking for offline solution, maybe you know something? Thanks
Hi Max, I have to say I am not sure. There are all sort of devices being developed now to continuously measure ECG signals, but I have no experience with their reliability. For example, with a quick google search I found: www.welchallyn.com/en/products/categories/cardiopulmonary/wearable-ecg-monitors/tagecg-wearable-ecg-sensor.html ; www.vivalnk.com/ecg-monitor ; www.amazon.co.uk/EKG-Heart-Rate-Monitor-Electrocardiograph/dp/B073VW2ZZV . But as I said, no experience with these :-). What is your goal with the measurements? Thanks for commenting!
@@TheQuantifiedScientist Thanks for asnwer! TAGecg sensor looks good, but "A/D Sampling Rate: 250 Hz" are you sure it is enough for good ECG quality? As i'm aware most ppl recommending at least 500Hz with a better choise of 1000Hz. Vivalnk's "ECG: 128 Hz" seems to be not enough too... The one from amazon is 200 Hz. So right now my polar h10 beats them with 1000Hz sample rate, but there is no way to get raw ECG data from sensor, because it not stored... My main goal is to increase lognevity & lifespan. (You can begin with David Sinclair's book if you interested, then deep more into mTOR, AMPK, SIRT, fasting - Valter Lungo, Autophagy induction - Guido Kroemer etc). One of the key thing is to monitor some of self data, check where it goes, what to work on etc. CVD diseases are biggest reason of people dying on our planet, so for now i'm focusing on getting detailed monitoring my heart data, which can analysed, processed and be shared with doctors. Also during collecting some data (i'm collecting food & nutrients, drink, toilet actions, gym excercises, stress, mood - 100+ events per day, and some 3rd party tools like withings sleep/body cardio/go and some blood/urine/ultrasound scans etc) i want to find some correlations and check some ideas (for examples check if some molecules like NMN or Resveratrol have effect on my body). And see how fast my body is aging and where im at with it :) Precious ECG data (for example how hearth reacts to stress) should be a huge indicator for measuring health status, trends, changes in body.
Hello I own a fenix 6x and oura ring Garmin has just updated the software and now connects all variables when it comes to accurately indicating that you are rested enough to train Could you check it out?
Hi Dennis! Great idea! I actually wore a Freestyle Libre (the sensor they use) for 6 weeks and also tracked my food-intake in detail. It seems Veri (just) the app that interfaces with the Freestyle Libre, correct? I'll see if I can make a cool video about my blood glucose levels at some point for sure, just have to analyze the data still :-D . Have a great day!
@@TheQuantifiedScientist Sorry for the late reply > It seems Veri (just) the app that interfaces with the Freestyle Libre, correct? Sadly I'm not sure. Very new to this myself. That being said, I stumbled upon Veri because it seems that for some of these sensors you need a prescription from a doctor and for some you don't (and I think you don't for Veri)? At least here in the US. > I'll see if I can make a cool video about my blood glucose levels at some point for sure, just have to analyze the data still That would be super cool! :) Thanks again.
Oura's crazy subscribtion model is putting me WAY OFF! I was going to buy it, but I'm not satisfied by providing my data to someone, and then paying them to get it back! That is completely and utterly dumb!
Hi @thequantifiedscientist! I'm very interested the Oura Ring it but I often get cold hands, meaning less blood flow in my fingers. Do you think it will drastically reduce the accuracy of the ring?
Does OURA really measure HRV? I believe it's rather pulse rate variability, right? I mean, OURA doesn't measure heart rate, it measures pulse rate. It's a big difference for scientists ;-). It might fit for young healthy individuals but potentially can be misleading with people who have cardio-vascular conditions...
Hello, Can you help me please find a reseller in the US, I would like to buy a few rings but can't quite find someone's email to contact for the ring. if you could help me it would be appreciated. Thank you!
Hi Marius. The Scanwatch does not track HRV as far as I know, or at least not in the same detail. For both sleep and HRV I would choose the Oura Ring, though for sleep tracking Fitbit seems to do better. Have a good one!

It works regardless of our desire and regulates, among other things, our heart rate, blood pressure, breathing, and digestion.". (www.health.harvard.edu/blog/heart-rate-variability-new-way-track-well-2017112212789 ). From what I understand arrhythmia is "due to problems with the electrical conduction system of the heart." (wikipedia), and it can also go hand in hand with abnormal heart rhythms (so the way the heart beats) .
However, in tracking HRV, it might be that I cannot easily distinguish between the "good" HRV and arrhythmia. Both cause variation in the time between heart-beats, but the underlying cause is different.
I am not a doctor or a HRV expert, but this is my best understanding. I would have to take some time to read more about it to give you a better answer. Hope this helps though!
Have a great day!
@@TheQuantifiedScientist thanks Rob!
@@azatello You're welcome
Also how do you get heart rate variability off the Polar H10? Mine just does rough, low resolution (but accurate) heart rate.
My Oura ring doesn’t catch the lowest heart rate compared to my emfit. It seems like the emfit has higher resolution.
Is the HRV only valid for when you are sleeping? Other people mentioned the HRV on the oura ring is only helpful to know your sleeping HRV
What app do you use to track your HRV during night/day with the chest strap?
Curious what app did you use for polar H10 to capture the sleeping HRV ? Thanks
May I ask what software did you use to take the HRV measurements? As far as I know, there are some apps out there such as Elite HRV but I am not sure how accurate they are.
Great video! Do you know any wearable (strap with ecg or somethings like that) which can be used to get ECG 24/7 with good resolution (to process raw data for HRV analysis etc) and can work offline for a few days and then sync to phone/cloud over BLE and then export raw ecg data? Right now i'm using polar h10 with Elite HRV, but there is few problems - the hrv app sometimes restarted and loses recordings, and the most thing to worry with polar is permanentl bluetooth signal emmitting near my hearth and that can be dangeroues for health. So i'm looking for offline solution, maybe you know something? Thanks
Hi Max, I have to say I am not sure. There are all sort of devices being developed now to continuously measure ECG signals, but I have no experience with their reliability. For example, with a quick google search I found: www.welchallyn.com/en/products/categories/cardiopulmonary/wearable-ecg-monitors/tagecg-wearable-ecg-sensor.html ; www.vivalnk.com/ecg-monitor ; www.amazon.co.uk/EKG-Heart-Rate-Monitor-Electrocardiograph/dp/B073VW2ZZV . But as I said, no experience with these :-). What is your goal with the measurements? Thanks for commenting!
@@TheQuantifiedScientist Thanks for asnwer!
TAGecg sensor looks good, but "A/D Sampling Rate: 250 Hz" are you sure it is enough for good ECG quality? As i'm aware most ppl recommending at least 500Hz with a better choise of 1000Hz.
Vivalnk's "ECG: 128 Hz" seems to be not enough too...
The one from amazon is 200 Hz. So right now my polar h10 beats them with 1000Hz sample rate, but there is no way to get raw ECG data from sensor, because it not stored...
My main goal is to increase lognevity & lifespan. (You can begin with David Sinclair's book if you interested, then deep more into mTOR, AMPK, SIRT, fasting - Valter Lungo, Autophagy induction - Guido Kroemer etc). One of the key thing is to monitor some of self data, check where it goes, what to work on etc. CVD diseases are biggest reason of people dying on our planet, so for now i'm focusing on getting detailed monitoring my heart data, which can analysed, processed and be shared with doctors. Also during collecting some data (i'm collecting food & nutrients, drink, toilet actions, gym excercises, stress, mood - 100+ events per day, and some 3rd party tools like withings sleep/body cardio/go and some blood/urine/ultrasound scans etc) i want to find some correlations and check some ideas (for examples check if some molecules like NMN or Resveratrol have effect on my body). And see how fast my body is aging and where im at with it :) Precious ECG data (for example how hearth reacts to stress) should be a huge indicator for measuring health status, trends, changes in body.
Hey how did you figure out the hrv for the polar strap ? Did you use elite hrv or calculated it yourself ?
Hello
I own a fenix 6x and oura ring
Garmin has just updated the software and now connects all variables when it comes to accurately indicating that you are rested enough to train
Could you check it out?
Top Beitrag!!!!
Thanks so much!
Is it possible to use the ring as a HRV-biofeedback device, such as the Stress Eraser?
Please can review of Omron heart guide watch
Hey! Have you heard of Veri? It's a continuous blood sugar tracker. Would be really interested if you were to make a video about it.
Hi Dennis! Great idea! I actually wore a Freestyle Libre (the sensor they use) for 6 weeks and also tracked my food-intake in detail. It seems Veri (just) the app that interfaces with the Freestyle Libre, correct? I'll see if I can make a cool video about my blood glucose levels at some point for sure, just have to analyze the data still :-D . Have a great day!
@@TheQuantifiedScientist Sorry for the late reply
> It seems Veri (just) the app that interfaces with the Freestyle Libre, correct?
Sadly I'm not sure. Very new to this myself. That being said, I stumbled upon Veri because it seems that for some of these sensors you need a prescription from a doctor and for some you don't (and I think you don't for Veri)? At least here in the US.
> I'll see if I can make a cool video about my blood glucose levels at some point for sure, just have to analyze the data still
That would be super cool! :)
Thanks again.
Can the Oura ring detect and warn you of a heart attack or heart abnormalities??
Oura's crazy subscribtion model is putting me WAY OFF! I was going to buy it, but I'm not satisfied by providing my data to someone, and then paying them to get it back! That is completely and utterly dumb!
is there a good device to measure heart rate/variability, and o2 sat?
How good /accurate is the HRV measured by the iWatch 6 ?
Did you end up doing a blind test between your personal mood diary and readiness score?
Can you test Welltory App HRV?
Hi @thequantifiedscientist! I'm very interested the Oura Ring it but I often get cold hands, meaning less blood flow in my fingers. Do you think it will drastically reduce the accuracy of the ring?
Good question. I have this same issue. Did you resolve? Did you get the ring?
Does OURA really measure HRV? I believe it's rather pulse rate variability, right? I mean, OURA doesn't measure heart rate, it measures pulse rate. It's a big difference for scientists ;-). It might fit for young healthy individuals but potentially can be misleading with people who have cardio-vascular conditions...
Are you compensated by the company?
Hello, Can you help me please find a reseller in the US, I would like to buy a few rings but can't quite find someone's email to contact for the ring. if you could help me it would be appreciated.
Thank you!
So what's your choice for sleep and HRV tracking? scanwatch or oura
Hi Marius. The Scanwatch does not track HRV as far as I know, or at least not in the same detail. For both sleep and HRV I would choose the Oura Ring, though for sleep tracking Fitbit seems to do better. Have a good one!
