Reference devices:

Apple is finally competing with Oura and Whoop when it comes to health tracking, by launching the Vitals app as part of watchOS 11. But can you now replace your Oura Ring or Whoop Strap with an Apple Watch? Well today we’ll find out! We’ll do quite a bit of testing and also compare the Vitals app to the Oura Ring and Whoop Strap’s apps. I’ve tested the Vitals app over the last weeks by wearing an Apple Watch Ultra 2 on my left arm and an Apple Watch Ultra 1 on my right arm. I am testing the Vitals app with the Apple Watch Ultra by checking how consistent the measurements are between two Apple watches. My hypothesis is as follows: if for some metric the agreement between both watches is quite low, then in that range of measurements the vitals app is not very sensitive. However, if there is a strong correlation, then it is more likely that the measurements are reasonably good, even within my day-to-day variation. The reason I stress normal “day-to-day” variation is because I never felt sick in this period, so there were no major physiological changes to my body. I chose the Apple Watch Ultra, since this is the largest and heaviest of the recent Apple Watches, which increases the chances of inaccurate measurements because it might move a bit more on the wrist. And, since all recent Apple watches basically have the same sensor, I expect other lighter models to do at least as well or even better. For this test I wanted to make sure the measurements of each of the two watches were completely independent, so each Apple Watch Ultra is connected to a different iPhone with a different Apple account.
But first, what is the vitals app, and how does it work, and what CAN, and more importantly CAN’T it do? Well, in essence the Vitals App is “just” a new way of visualizing the data your Apple Watch collects. Historically the Apple Watch and Apple Health have been quite bad at presenting health and activity data to the user, and the vitals app is an attempt to fix that. The vitals app focuses on 5 key metrics: resting heart rate, oxygen saturation, breathing rate, sleep duration and wrist temperature. Each morning the Apple Watch tells you the exact values of these metrics, and it tells you if one or more of these were outside your normal baseline. The easiest way to check this is by looking at your Apple watch, where it is displayed as an actual app. However, the downside is that on the watch you can only see the detailed data for today, and an overview for the last few days. If you want to look at all your data in detail, you’re going to have to take out your iPhone. Initially I thought it would be available as a separate app, similar to the Fitness app for sports. But, unfortunately this is not the case, it turns out that your vitals data is displayed in the health app. It is basically a separate metric within the health app, similar to how your heart rate is presented for instance.

I’m sure you’ve heard this from many viewers, but you focus on comparative data and a proper application of the scientific method in testing smart watches is highly appreciated. Great work!

[mightypine]

This is great. Could you compare Bevel and Athlytic?

[StaszekD-iz]

Great video, I would like that you could test iOS apps like Bevel, Athlytic and compare it to Whoop!

[Alex-hvir]

I’ve had a fever while wearing my Apple Watch. It detected a +1.9 C difference from standard. It also detected a much higher respiratory rate.
Surely enough, the morning after that night I was sick

[JiajuChen]

Had multiple fevers, my ultra2 always straight up caught the anomalies in breathing and temp quite well. Blood oxygen is almost useless as aways though.

[mangatmangat]

You are the only one who does scientific based review and this is great. Awesome work man!

[Nicke_FIN]

OURA RING 4 is out! Hoping you are planning on getting one and do a review! 🙏

[BrunoDECOURCY]

I wish you could test apps such as Bevel for example afterwards.
Thanks for your videos!!!

[ZachGottlieb]

Great work as always. Would suggest axing the background music while you’re talking though.

[carlosmiguel]

Please test mi band 9 if you have the time. Waiting to buy one but want to see your review 1st. Thanks

[Omnicronnn]

Good experiment design. It's great to have researchers for things like this; kudos!

[guillaumedchampeau]

The Bevel app brings deep, Whoop style data interpretation to Apple Watch. Would be great to have your thoughts/review on it!

[bernardofranco]

I never comment on anything, but you sir, are doing public service, and in a scientific and useful way. So, thank you very much!

[blickwinkel]

Hi there, a big thank you basically to all the videos you make. You put an incredible amount of work and effort into making sure we get good content. Thanks for that 👍

I would like to know one thing. If I interpret it correctly, then the Apple Watch measures very accurately, only the evaluation of the data is not good. That would mean that all you need is a good app that processes and interprets the data.

Have you already tested apps like PeakWatch, Athlytic and Bevel or can you make a video about such a comparison? That would be great.

Personally, I want to use only one device and not several. In the end it's my Apple Watch, as I also want to use a smartwatch.

I would be happy to exchange experiences. Which apps do all of you use? Regards

[ameerbarakat]

Thanks graet vedio . Sleep tracking mi band 9 💤

[robertjleter]

Please check blood pressure, HRV, VO2max, Sleep stage etc accuracy on the Huawei D2 watch

[iddobarzilai]

Can you make a video on different mobile apps for sleep tracking? Both stand-alone and ones that use the information from your smartwatch.
Thank you! Love the Channel

Bro I still don't get why this is still a discussion point, Apple depends on 3rd party app developers for apps that interpret this data Whoop or Oura like, i use an Apple watch and use Bevel after moving from Athlytic for this specific reason, I prefer the Apple Watch over every other device because for the most part, like you've shown on many of your videos that it is one of, if not the most accurate fitness device. This assessment would have be more fair if you had a Bevel subscription on your Apple Watch and compared that to the Oura and Whoop, lets all still remember that Apple is a Tech company first

[alessronow]

+1 for the comparison between Athlytic and Bevel. Apps using the same set of data from the Apple Watch & Health, interpreting it way differently.
