First, I test their sleep tracking accuracy by comparing them against a scientific EEG device. After that I compare that to the results of a full scientific sleep polysomnography test I did. I will also take a scientific look at heart rate variability, temperature, breathing rate, resting heart rate, and the readiness score.

So impressed at your methodology! Thanks for the hard work!
Thank you for making by far the best reviews: by far the most rigorous, very clearly explained, and with thoughtful timestamps & organization to boot! Thanks Rob!
Very clear explanation, just like a scientific report would be!
Thanks Jonathan!
This is the info we all need and almost nobody makes. Keep it up, great content!
Absolutely the most useful video on Oura rings. I am buying one and was wondering how accurate it is and wanted to see real calculations that show exactly how accurate it is. Thank you kindly, this video obviously took you lots of effort and time. Much appreciated!
I've been waiting for this one - thanks for your work!
This was so thorough and helpful, thank you! Oura should hire you as a consultant :)
I don’t have words. Man, this is awesome what you do. You scientific approach is great.
I appreciated the second follow up video from your analysis last year.
Awesome, as usual!
Great video. I love all the in-depth analysis you did here. The charts and your methods are great, even if it is only an n of 1. Subscribed
Hands down the best reviewer when it comes to smart watches/bands
Really well done as always
Really fantastic video! You put a ton of time and research into the Oura ring which was extremely beneficial. Great data charts and summary!
Thank you - always enjoy your videos!
Nice rob. Wow already over 30k subs. Lets go to the 50k. Tim
These videos are such a gem!
Uses rectal thermometer every morning, my man's dedicated to science. Great video! easy sub! Looking forward to going through your videos!
Nice u got yours to review I’ve been waiting for two weeks with zero updates on shipping.
Your reviews really help me decide whether I should keep my apple watch 4 or get something else and consistently, for my use (no sleep tracking), the apple watch comes out on top. Thanks for saving me time and money!
Awesome job!! Great review!
awesome comprehensive scientific review well done
Great video! So much value provided!
Woow... I can't believe that you have only 40k subscribers for being the only serious review out there, this very unfair. It's a Shame people prefer just to watch review from people that just show the specs and the price🤦🏻
I wish you all the best and I hope that you channel will take off soon!! :D
Wow !! Your reviews are always interesting !! I have the Oura Ring and use it with Apple Watch series 6. I agree completely with your conclusions. Thanks for your videos 🙂
Thanks for sharing Mimi!
Thanks Robert for another great Video. I will keep my apple watch 6 for now :)
great content. respect man.
Great video, friend!
Thank you very much!
Thank you so much for the video! Very complete and informative.
Looking forward to the Oura v3 review :)
Awesome analysis! Thank you.
Waiting for your review on Garmin Venu 2. Fingers crossed!
I have already returned Venu 2 after just one week of usage. Sleep tracking is a joke, you'll see venu2 asking you "you are sleeping, do you want to wake up?" Also go tweet garmin to send Rob a test sample.
Haha. This is the level of testing I want to see! Great job
Thank you for your work Rob! I really appreciate your advice. I have been looking to improve my sleep quality and it sounds like the Fitbit Inspire 2 is the one for me! Could you also do an analysis of Lumen, which is promoted as a way to track and improve metabolism?
By the way, have you ever considered testing smart weight scales such has the one from Fitbit or Xiaomi? I have always wondered how precise and contant are the measurements of certain variables such us fat or muscle percentage.
Kudos for the outstanding channel!!!
Well done. Would love to see the same device tested on more people in the same way. Maybe for some people the sleep staging is better.
Excellent video as always, I would like very much if you could analyze the Garmin Venu 2 because they have modified the algorithms of the sleep measurement and Body Battery, there are many rumors that it is better than the Oura Ring measuring sleep.
Hi Franco! Thanks for the suggestion ! I emailed Garmin if they could lend me one, but they were having delivery issues, so I have to wait until June at least
+1 great idea! this seems to be very exciting. I'd also like to see Rob analyse the new version :-)
@@TheQuantifiedScientist Any plans to test the Samsung Watch 3?
Awesome Video Thank you !!
The only MAJOR flaw you need to consider, is the Oura Ring systemic battery issues. If you are lucky when you buy the ring, it will fail before the warranty runs out and you might get more then 2 years use. And if you are unlucky your ring will last for 2 years and VERY soon after the battery will fail.
I have had 2 fail both at about 14- 16 months and many friends have also.
So buy knowing that it is a disposable device and you will need to buy a new one every 2 years or so.
Wow, such a great job! Instant subscribe :)
I would love a video comparing sleep stats across wearables.
Amazing comparison. Thank you.
For me the awake time is pretty spot on, but mostly because I don't move at all when I sleep, which I imagine isn't true for everyone. I agree that the time spent asleep is a useful metric, which the Oura helps track.
I have a suggestion - you could compute the maximum cross-correlation between the sleep stage readings, as it would serve to summarise the comparison.
Thank you so so much for this valuable information. You are so awesome.
Fantastic video and a fantastic job! Will you do something similar with the Whoop strap?
Best review ever! Have you ever testing or compared your zMax (EEG) with a tool that known to be more accurate in predicting sleep pattern?
Hi Rob, I'd like to support your results by my observation. I also used to wear two Oura rings for a week or so and compared sleep stages. Few nights I wore them on different hands and few nights on the same hand (not the same finger), but sleep stages didn't overlap as expected. Actually I've been quite disappointed and confused. I didn't compare data scientifically like you, as I compared only sleep reports. Now I rely only on readiness report. Geat job as usual! I appreciate your effort and like your videos. BTW, if you wanted to compare three ORs I can lend you one. I'm in Bratislava 😉
Hi Miroslav, thanks for sharing your observations. I think two Oura Rings is enough, though it would be cool to wear 10 just for one night.💍💍💍💍💍💍💍💍💍💍 Sleep well!
Thank you for sharing!!
Thanks for watching!
@@TheQuantifiedScientist ....a real great study. I respect your persistence very much !!!
Superb sir 😄
Thanks a lot 😊
great video - thank you
I love the new intro ending. As always your tests are detailed and easy to understand. Keep up the work!😀
Thank you! Will do!
Absolutely amazing video, thank you. Any plans to make the same video with the new Gen 3 Oura ring? Thank you again.
You fulfill my dreams even before I have them :-)
I just bought the series 2 for 125 bucks which I think was a pretty good price for someone who wasn’t even really interested in this thing at all and has an Apple Watch. What I’m getting from your analysis is that this device is about 60% accurate and I paid fair market value. But my wife will be happy that now I will wear my wedding ring even if it really isn’t my wedding ring
Thank you! 🥦🦖
Super useful review, thank you so much!!
Would it be possible to look at the code for calculation of feature importance of Readiness?
Thank you!!!!
Hey, Rob. Please make an updated review on Withings watch and Fitbit inspire 2(if it has some new updates.)
You should do a video showing how your EEG results compare to a polysomnography.
Awesome Thank You
Predicted or reported? Thanks for the video and keep up the great content!
Unbelievably useful! Thank you! I am ditching my whoop strap after 6-months use because I am concerned about the constant EMF exposure, although I remove it to sync it up via Bluetooth. I use it to track both my sleep and workouts to make sure I am doing the right level of activity. Given your experience, what would you recommend as the best device for tracking and advising on sleep and activity?
You are the best
Man I really hope you upgraded to Oura ring 3 and repeat these tests, i'm so curious to see if ther's any improvment!
Thanks for that. I will not be getting one yet based on that data.
Very nice video and hard work. I would like to ask your opinion what is the best choice for a sleep tracker. Thank you 😊.
amazing
Great video! I see a possible fault in your setup at 2:18: you are wearing the rings in different fingers. For consistent data, you should keep your ring in the same finger.
If you could do the accuracy test of circular as soon as it will be launched, I would be grateful.
Thanks a lot for your work! Would you also analyse the go2sleep product? I'm wondering if we really can rely on its measurement.
Hi .. great info in the video!! Just wanted to check which app you use to get HRV out from Polar H10 ecg data?
Thank you mate for your brilliant work. Are you going to review the Biostrap by any chance? I have one but I'm thinking of getting Whoop 4.0 or Oura Ring 2 since Biostrap doesn't have temperature measurement.
I do wish you had used the newer software--there's a chance that has made a huge impact on its possible improvements on sleep stage tracking.
Based on your recommendations I'm tempted to go with a fitbit, but I really hate the idea of supporting a company that's hiding some data in its interface behind a premium paywall.
Pre-order Oura Ring 3 and WHOOP 4 is out too ;) would like too see ur review :)
Fitbit Sense seems to have many of the sensors the Oura ring has. When you complete testing ecg, respiration rate, and skin temp. Will you recommend one?
fitbit inspire 2 show great results in Sleep stage tracker in your Inspire 2 Review video, do you think the charge 4 perform the same ?
Like always I really enjoy your videos keep it going and good luck.
I'm curious about that too! Inspire 2 vs. Charge 4
I think charge is even better!
I think charge is even better!
Does Oura use any AI technology that "learns" what your sleeping metrics tend to look like? Granted, I don't know how it could do that without manually correcting which stages were correctly/incorrectly identified. (But, then again, you're the sleep expert, not me!) I ask because that might explain the inconsistencies between your New and old Oura rings.
Thanks for this video, great methodology!
I was going to buy one but honestly this really dissuaded me, whats the point in obsessing over sleep data thats almost as much noise as it is accurate meaurement
Would you please evaluate the MUSE S headband for sleep tracking?
Thanks for the great review! It sounds like the hardware capabilities of the oura ring are very solid, and quite accurate. Sounds like it's just a software issue on their sleep staging algorithm. I've been using the oura ring and the HR and HRV have been quite useful for day to day tracking.
Nope, they're horrible at REM and it's just a guessing game, because the ring CAN'T DETECT RAPID EYE MOVEMENT which is REM. Even their Deep sleep
and light sleep isn't as good as they claim.
For athletes who bottom out in the mid 30s during sleep, I bet the OR is much less accurate. That was my experience comparing it to the emfit.
I’ve heard people talk about the Apple Watch and oura ring combo as the best possible combo for fitness tracking. Any chance you can make a video on what you think about that?
Disclaimer: only works if you’re rich
What do you think about the validity of steps and calorie burn on the oura ring?
gud job 👌
Seems like the fitbit inspire 2 is hard to beat? In the confusion matrix it’s consistently at least 60% on all fields in sleep stages
Can you please review the muse s and compare it to the dream 2? I have the Oura ring, but i would like something that gathers more accurate measurements on sleep.
Unfortunately, the Muse 2 offers only extremely limited sleep details. For example, it doesn’t offer time spent in different sleep stages. The rumor is that full sleep stats will be part of an upcoming subscription package. That makes it hard to do a comparison at this time. And as for the Dreem, it is no longer available to consumers.
@@markolson6161 thanks
Could you compare the total amount of each sleep stage predicted by the ring vs the actual amount (-> disregarding time) ?
are there any differences to the series 3 now? Oura says they have taken your critics and updated the ring. Have you compared the series 3 to series 2 or your scientific measures?
This guy is so intelligent AND attractive. I hope he finds a good significant other in his life.
can this give you a good idea of when your core temperature minimum is during sleep?
I believe to have watched every video you published, in the end, the Apple Watch is always the best. Good what you do, but I think you should make some additional effort when you compare Apple Watch with the other devices, also looking at the budget and use cases, otherwise it seems you are advertising Apple products. For example, for fitness purposes only, a Garmin seems just fine and is much less expensive, probably I forgot also some other device but that one is on top of my list in case I don’t want a Smart watch, but just a fitness tracker.
Sorry to ask perhaps the obvious... what can people do assuming they know when they go into light / deep / REM sleep?
I use a tracker to tell me how much I sleep... but beyond that, I am not sure what to do if I have the additional information.
good
How do you use the h10 to measure your heart rate during sleep?
Do you plan on testing the version 3 ?
Can you do a review of Noise Colorfit pro 3 snartwatch ?
Could you please do a study of Amazfit GTS2 mini???
Wow, I love my aura ring but this shows the technology is very far from perfect! - From all your research so far, what would you say is the most accurate consumer sleep tracker available right now? - is it still Oura, or is it Fitbit?
Not Fitbit lol
Finding my Vivosmart 4 has very good sleep tracking. Would be happy if he tested it for sleep stages as he does here for the Oura ring
Very good for what reason?
At 23:24 of this video, Rob says Fitbit.
It seems like Rob has always said that Oura was inaccurate with sleep staging--see his first sleep test on Oura ("Oura Ring Scientific Sleep Test (Review)" released Apr 20, 2020, th-cam.com/video/atWcp6FmnbE/w-d-xo.html)
Similarly, he's consistently found Fitbit to be the best at sleep tracking, as stated here in his recent Nest Hub video: th-cam.com/video/KjCX79zdZ-k/w-d-xo.html
@@andrewhwang2910 Thank you for your reply, with links, clarifying Fitbit and Oura according to Rob.
Is it still possible to get all this data out of the oura ring ?
any chance you could do the same with the whoop strap?
P.s. I think there’s an opportunity for you to create a new wearable for the Apple echo system...a consumer EEG device worn on the head that sends its data to the Apple Watch, and an App on iPhone/iPad/Mac/Win that can interpret this data. If you funnel this sleep data into the über Readiness Score algorithm/app (see my previous comment) then it would be über über...
