I am excited to share with you my latest systematic test of the Oura Ring 3. As many of you know, I think the Oura Ring has been one of the best health trackers for a while now, and I even showed in a recent video how it helped me track my COVID-19 infection. However, one area where the Oura Ring has fallen short is sleep stage tracking. But, Oura has recently introduced a new beta sleep stage algorithm that they claim will be a significant improvement. In this video, we will be taking a first quick look at this new algorithm and see if it lives up to the hype. Additionally, I will also be re-testing the workout heart rate feature that was introduced with the Oura Ring 3. In my original test I had some issues with this feature, and today I wanted to see if they made any improvements. I hope you are as excited as me to see how these new features stack up.

Now, as you might know, after the release of the Oura Ring 3, Oura introduced a workout heart rate feature, which allows the Oura Ring to track your heart rate during 5 types of exercises. For now they only allow heart rate tracking during indoor and outdoor running, indoor and outdoor cycling and walking. So, to test this workout heart rate tracking feature I will compare the measurements of the Oura Ring 3 to an ECG chest strap from Polar called the H10. Now, the Polar H10 has been used in quite some scientific studies, and it was actually shown to be more reliable for heart rate tracking during medium intensity exercises than a professional scientific Holter ECG monitor. Next, for the sleep stage tracking I compared the sleep staging tracked by the Oura Ring 3 to an EEG device called the Dreem 2 that can actually measure my brainwaves, and has been shown to be relatively reliable at sleep stage tracking. It is not the gold standard in sleep stage tracking, but it should give us a good first impression of how the Oura Ring performs, and also how it compares to more than 40 other devices I tested over the last years.

It is so nice to have here a person who invests so much time and efforts in proper reviews! I've bought a device wich I hadn't even been considering due to your reviews and it appeared to fit my goals perfectly. So thank you <3

[FrancescaDePaolis]

Hands down, the most accurate and in-depth review I have seen so far. Thank you for putting such amount of work to review the performance of the Oura ring. It is highly appreciated.

[leoott]

Thank you so very much, it is highly appreciated that you take your time to bring this unbiased scientific review to all of us!!!

[vaibhavdeshmukh]

You're absolutely the only guy I refer to for buying fitness products. Thanks!

[MyrtleBeachWebAngel]

Oh wow! I am so excited to hear this update. Thank you.

[stepsbeyondtheeventhorizon]

This should be the gold standard for tech reviews. Absolutely tremendous job. Easiest sub I've given in a while.

[ChiknaAhmad-gyoo]

Brother, thank you for your hardworking and the high quality review. Keep it up.😤

[idolevy]

Thank you for this video.
Can you please review the new Huawei Watch GT 3 SE with the new sleep algorithm

[onetwofourfive]

So you pay 314-576 eur depending on colour and material for a ring and then you have to pay monthly subscription 5-6eur for more data that is collected. Is this a freaking joke? No thanks

[itskareemelsayed]

Yessss finally I've been waiting for this video forever. Watching now!

[jan]

Thank you so much been so excited for this to come!!!! Thank you for all your hard work looking forward to the next update.

[forzaviola]

Tremendous work. I was waiting for this review, and have now bought an Apple Watch SE instead because of it.

Hopefully Oura can continue to improve enough to get back in the game.

Thanks for the review, and hope you’ve recovered fully from Covid!

[purrsnpurls]

This is awesome, thank you so much!
I know you focus more on exercise, but would you ever consider making a video about suitable trackers for people suffering from PEM, e.g. due to Post-Covid or ME/CFS? The number of affected people is growing and while tracking your heart rate is recommended it is difficult to find accurate information. You're the one I'd trust the most to make a well-researched video about that :)

[kukensson]

You do an exemplary work. Truly. Real, hard science

That was a very useful first review! Thanks for making these data driven comparisons.

[chriskozlowski]

Have you tested the accuracy of HRV? Curious how accurate it would be at rest. Your data has me concluding it wouldn't be reliable while exercising.

[VegasPerformer]

Great video love all the in-depth information I appreciate your effort gathering all the data.

[razaliibrahim]

Hi Rob. Appreciate sooo much if you could do a review for the Huawei Watch D that has the blood pressure measurement and ecg.

[cyriacbere]

Thank you for taking the time to review these things
