Could you please advice the best device for sleep tracking of my father who has high blood pressure? He went for sleep test at hospital. And doctor was told he has very low oxygen during that middle of his sleep. Any device that detect not only heart rate, oxygen level as well? Appreciate your advice.

[@christianwagner6357]

My dude took a rectal thermometer every day for us, thank you!

[@tahmidt]

This channel needs to EXPLODE in popularity!

[@pandakso3365]

Showed a guy with the thermometer in his mouth too 🤯

[@chrisogrady28]

That's a pleasure more than a pain

This dude drew his blood every three weeks to measure his white blood cells in the lab in order to review a product. And he always looks like he's going to bust out laughing. Best reviewer ever.

[@denislzx827]

such an underrated channel

[@TheQuantifiedScientist]

Thanks Denis!

[@UXDiogenes]

Ya for real

[@chrisogrady28]

Not really, only been uploading for 1 year with 25k subs and consistent view numbers in three tens of thousands is amazingly good. You can't compare new creators against established ones with millions of subs.

[@destituteanddecadent9106]

@@chrisogrady28 4 months later, he's still pretty small. I guess because he specializes in fitness tracker and smart watches? His specialty being what makes the videos so good ofc. I feel people would come to watch when they're considering buying, but it's not the kind of content millions would subscribe to and seek regularly.

Commenting to bump the algorithm because such great content needs to be seen!

I'll do the same :-)

Yup same here

[@traolin5877]

Man, I'm subbing solely because of that rectal thermometer. That's some dedication

[@GodKing804]

Exactly

[@evolutionofj]

I think this is literally the best tech review in this genre that I have literally ever seen! Thank you

[@bgheyle]

Hey Rob, just wanted to let you know how much I appreciate your videos. I think it's amazing you take the time to make these in your free time, using your knowledge and passion for data/science to educate us fools. In this era of "influencers" and full time "content" (about whatever) creators who make 10mins long videos just saying something is "great", without any testing or background and mainly because they got it for free, you stand out so much more than you probably realize. Your content is gold. It's to the point, very understandable and your stupid jokes crack me up. As a sucker for health, sport and science I really love seeing all these health tools being put to the test. Also, since I recently bought a Huawei Watch Fit, I'm (NOT SO) patiently waiting for you to make more videos about it ;-) Your first video about it is a big reason why I bought it so yeah... Anyway keep it up man!

[@lanceklein2746]

Yes! PLEASE don't fall into the trap of being yet another channel hawking goods. I truly hope you can make a living while continuing to be impartial and fact-based 🙏

[@ethereal_arcana]

Perfect timing as I just ordered the oura ring. This gives me more confidence in that decision.

[@DanDascalescu-dandv]

As long as you don't use it to track sleep :)

[@MoneyGamerMG]

Was it worth it?

[@shamsulazhar]

5:48 He said rectal thermometer , then shortly followed by a video of a guy with a thermometer in his mouth..... 😱

[@TheQuantifiedScientist]

Haha, some clips just weren't suitable to include ;-)

[@DavidWard14]

Hahaha. I noticed that too and thought "ewww" at the time. "ewww" is a technical term.

[@Dad_K]

Lol dedication to science!

[@Winium]

@@TheQuantifiedScientist you should have included the taste score then as well, could be valuable data ;)

[@adammazor1820]

Thats why the second guy looks sick 😂 😂 😂

[@sobeautifulsrilanka]

Thank you so much for creating this channel and making these videos. What a service to planet earth. I’d be interested , at the conclusion of every test, in an ongoing accuracy ranking for the various fitness trackers in the domain your test measured: sleep stage, sleep score, HRV, RHR, stress etc. Then after every test you do, rank the device against their competitors in the domain that was tested. Example: Heart rate tracking domain (1st) Apple Watch (2nd) Fitbit Charge 2 (3rd tie ) Oura Watch , Fitbit Sense etc. I wear both a Fitbit and Apple Watch and their automatic morning RHR measurements are consistently about 10 beats apart. I don’t know which device is giving the more accurate measurement.

[@daysirc]

Only 9k followers?, you should have way more. You do really interesting tests and analysis of the devices. I hope more people discover your channel :)

[@HKnK8]

Just came for a quick review and gets knowledge dropped on haaaard!. This is some next level reviewing. Scientifc as hell and I love it.

[@ebenvia]

This was a great analysis of the product! I like the objective view he took that was backed up by data

[@youhavetogotheretocomeback]

Awesome as ever. Would love to see a video of you and colleague where he talks about how he optimises his readiness score.

[@djgarrett21]

This is such a great channel! Data, analysis, real comparisons. Please become the DC Rainmaker of fitness tracking devices. So much marketing BS out there it is difficult to know how accurate these devices can be (or not).

[@nguyentminh]

Thanks Rob. You just saved us a lot of efforts and money. One thing I realize is that all common retail version wearables aren't accurate enough (less than 71% for sleep) , while most measurements aren't necessary to monitor around the clock. I don't even need sleep tracking to know how my sleep quality went, I can just feel it when waking up, as I'm sure most can too. I can feel my readiness in the morning and adjust my intensity schedule in the day.

[@roxbittman]

This was a really good one! I prefer the Fitbit because of the improved sleep tracking. One of the best things I learned in your video today was that the emphasis these watches and their algorithms put on Sleep Duration and timing is correct. I had previously questioned this because it seemed artificial or "too convenient" to score Time Asleep as 50% of the total Sleep Score (Fitbit). Fitbit gives Deep/REM only 25%, and Restoration (hr) 25%. I was irritated at the apparent casualness of these assigned values, but your video makes me reconsider! It is also helpful to know that the skin temperature readings may have some value. Fitbit Versa 3 and Sense measure skin temp at night as well, but they provide no analysis. I guess if one notices a spike in temperature at night, it is time to take a core temp and see how one feels! Thank you for these great videos; yours are definitely the most informative regarding health trackers.

[@marion1122]

Ah, thank you so much - I don‘t use an Oura Ring, but I really appreciate your videos. There are so many so called tests of wearables on yt, but they are more kind of unboxing. So, you one of a kind! 👍🙏

[@kingplays5369]

Das ist einfach genau der Channel den es auf KZbin noch gebraucht hat 👍🏼👍🏼👍🏼

[@greencoolmoss]

This is actually the BEST review, very scientific and simple!!. Maybe if you had a more clickbait title/thumbnail and the first few seconds of the video were high energy and attention grabbing.... it wouldve got the views this deserves

[@lanceklein2746]

Amazing video! I look forward to the day there is a device we barely notice wearing but gives accurate health stats continuously. Videos like this help us know how close we are

[@seb199]

Amazing channel!!! Finally a channel that supports statements with real data! Thank you!

[@TheQuantifiedScientist]

Much appreciated!

[@puesbien]

Hi seb

[@clabr7023]

Could you do some sleep tracking tests like this with a budget fitness tracker like Xiaomi Band 5?

[@themlgbrosftw4960]

Bumping this incredible video, you are doing god works. Taking a rectal thermometer for years in the name off science is something I can respect

[@sg_hokkien_opera]

Thanks, your videos are easily the most detailed reviews I’ve seen on the Oura ring.

[@sbstn451]

This is by far the most sophisticated and scientifically proved tech review I have seen in quite a while. Thank you so much for the video and for all the hard work you've put into it.

[@jkalafatas]

Great videos and research. Have you considered comparing Oura and Whoop? In the US at least, they seem like the two big options people choose from. I use Oura and love it, but Whoop appears better for fitness tracking and puts out more content on their podcast etc.

[@sergiutelbisz1955]

Your channel is amazing. This is what many reviews are missing. We want to know what we are buying not how flashy it is. Great Job Rob!

[@pckeenan13]

So happy I found you & your FASCINATING videos (@Kylegotcamera gave you a “ringing” endorsement...sorry could not resist). I so appreciate your dedication, conviction & time commitment to your research and the real-world insights these videos deliver. This has been a perfect Sunday morning watching your Oura ring videos! Please keep these wonderful videos coming! P.S. I am a fully admitted Biohacker geek...my specific passion is with PEMF.

You are my number 1 reviewer online from now on! I love your videos! So informative. Exactly what I was looking for. I with you become big as you deserve

[@colocolo49]

great job. i learned more about the product from one minute of your video than from the Oura CEO one-hour interview.

[@mypreciouscorner]

TQS, this is an excellent video. You compact a lot of data into a format that is easy to understand and retain. Impactful 18mins spent. Thanks!

Fantastic! These are the best reviews/tests I've seen on wearable tech.

[@TheQuantifiedScientist]

Wow, thanks Magnus! 😊

So much so for the self-proclaimed “most accurate sleep tracker”. Thanks, I will give it a pass as I was interested in it’s sleep tracking the most.

[@ugzz]

I've watched the last ~20 videos and this is some amazing data! Can't wait to see how some of the third party app testing for the Apple watch sleep tracking goes! These videos may actually assist in an upcoming purchase, so I really appreciate them!

[@Tiamo1519]

Great Rob! I think polar should be worth a try. In my opinion they do the best sleep tracking.

[@Allride_]

Talking about a in depth review. Good lord. Thank you

[@ktoso]

Thanks again for the videos, very useful to see another analysis after a year here. Been using a ring for almost a year now and been tracking your analysis about it - I agree it’s useful enough to enjoy benefits, but one has to mostly ignore the sleep phases heh :)

[@marioidsouza]

Good in-depth review. One suggestion is to state if you were blinded or not. For example did you see the sleep score in the morning, as that would influence your subjective and possibly objective measurements.

[@silviui.]

Great video, Rob! This gives us a new perspective. You have given us great value, pure gold. Thank you so much!

[@Martyn2160]

Overall I think your review is fair. But I have to say finishing the ring with professional equipment is a bit unfair as who has or would want to use that equipment every day/night when the ring is far more convenient if less accurate?

[@TheKiwNo1]

Such an amazing and intriguing video, thank you for putting it together. Subscribed with passion 🎉

thanks, quantified scientist, love this channel. Given the superior sleep accuracy as recorded by you of fitbit charge 4, why would anyone buy the oura over it?

[@liamdunne83]

Apologies for the bumping of my own comment but if anyone has a view on this, please let me know as I havent yet received my oura and may cancel my order for the significantly cheaper charge 4

[@martinkudlacek487]

thanks for deep scientific review!

[@KyleBaker]

Really wish you had clarified something--when you said there was a correlation between mouseclicks and keystrokes and the sleep score, you didn't clarify if it was keystrokes and mouseclicks the day before correlating to good sleep that night, or sleep that night correlating to strokes+clicks the next day. In other words; did doing lots of mental work lead to you sleeping better, or did sleeping better lead to you doing more stroking/clicking the next day? Seems based on language implications that you're correlating with next day's strokes/clicks, but wanted clarity on that. (Also, not sure if you're checking both, but that might be interesting?) Thanks for the great content.

[@megavitek]

nice job, could I bother you with a few notes? (jitter) Add some small random noise to a discrete variable so that the points don't overlap (or some KDE colorcoding). Eg. on temp plot. (linear fit) these fits don't look convincing at all. What is the R^2 or rather what is the fit beyond linear regression or after removing outliers? Maybe RANSAC regression? (accuracy) what is the random educated guess accuracy? Say randomly chosen RAM segments every few hours?

[@jonasrayet9369]

Hey, would you do a whoop review as a scientist since they are often regarded as the most precise. Great work btw thank you !

Check out the Fatigue Science Readiband 5, supposed to have 92% accuracy on comparison to EEG

What is the method you used to calculate HRV with the Polar H10? Polar's app doesn't provide it as far as I can tell. Love the video and your channel, keep up the great work!
