#Whoop #Whoop4 #Whoop4Review

- How I included heart rate testing data: I included all data after the 2024 summer heart rate update. 4 workouts were excluded due to issues with the reference device missing signal.
- How I included sleep stage testing data: I included all nights from 01-01-2024 until 2024-05-10 I had data for (the latest data I had data export for). This resulted in 54 nights of data with both good EEG and Whoop data.

Reference devices:

Timestamps:
00:00 Important Intro
01:26 Heart Rate Test
12:27 Sleep Stage Test
22:32 Body Temperature, COVID Detection
28:32 Conclusions

Wondering if you should get the Whoop Strap? Well, the Whoop Strap is one of the best all-round health and fitness trackers out there, and I use it every day myself. But, it is also not the absolute best device in any individual category, and I can back that statement up with data. [running] For instance, during most exercises, like running, it can track your heart rate accurately, and it is generally better than 70-80% of devices out there. And the correlations were similar for a second person I tested it on! [/running] [zmax] For sleep stage tracking it is also pretty good, being amongst the second-best devices, though again some devices are outperforming it. And for tracking and displaying your health data it also has one of the best and most interpretable apps out there. [/zmax] The Whoop Strap was even able to predict when I had COVID-19, but there are some caveats there we need to discuss. However, the Whoop Strap is not without its flaws. The data sharing of Whoop has always been pretty bad. It’s your data, so you should have access, and though Whoop has gotten better at this, it is not close to the level of detail that the competition provides. So, whether or not you should get the Whoop Strap really depends on what you want to do with it and how you intend to use it. So, let’s dive right into the data. Before doing that, I should mention I will add an affiliate link to Whoop below, which earns me a commission and supports the channel. I only accepted after testing it, because the Whoop Strap is genuinely something I can recommend to friends and family. Also, Whoop doesn’t even know I am making this video, the data was not filtered, and my opinions are my own.

Overall, I am happy with my Whoop Strap, and I’ve used it for many years now. There is still room for improvement though, and hopefully that’ll come over time. If you want to track everything, from exercise, to sleep, to health, and get an app that shows you that data pretty well, then the Whoop Strap is one of the main devices I would recommend. However, if you are interested in any one thing in particular, like just heart rate, or just sleep staging, there is likely a better device out there for you. And that brings me to the last downside of the Whoop Strap, which is the subscription model. There is no up-front cost for the device, but you will likely pay somewhere around 200 to 250 dollars a year to use the Whoop Strap. The upside is that you get a new device for free when they release a new one.

Man, you should make a website to keep track of all your reviews, with filters to sort by price range, etc and compares accuracy between devices. I'm new to sleep tracking and it would be so helpful. It's really difficult to sort thru and watch a whole catalog of YouTube videos to find the right product. Either way, thanks for what you do!

[lbgstzockt]

If the whoop was a one-time payment I would consider it, but a subsription in combination with a less accurate sensor means I will be staying with my Apple watch.

[GoogleGoogle-yyfr]

The subscription model is quite a bummer for me :(

[cryonuess]

Don't support subscription models, especially on software for hardware you bought!

[izrelli]

After watching many of these videos, it is nice to see how you provide such quality content while keeping a joyful smile most of the time.

[Fautra]

Could you review the Xiaomi Watch S3? Thanks!

[charlesg]

Thank you for sharing such comprehensive reviews from a long-term user's perspective. There's nothing else like it on Youtube. I have a Whoop strap mainly for heath tracking and tracking my sleep and my runs. I sometimes feel overwhelmed by the amount of data and, to be honest, I don't really know what to do with it.
I would be very interested if you could share how you use this data in your day to day life. How do you think the average person, who's just looking to improve their lifestyle habits, can best utilize these metrics? What level of accuracy is sufficient in this use case?

[paulochf]

Hey Rob! As a Data Engineer, I love your analyses. I wonder what things you use to create them or what kind of pipeline you created to process the data you collect. Do you have (or are willing to make) any videos on the topic?

[Cavs-Trade-]

Can you review the Oura ring gen 4. I’d like to know the results before buying one.

[mike]

Whoop is good, but much too expensive... similar situation as Oura. Thanks for the video Rob! Using both a Garmin FR 255 and Apple Watch SE 2, and I can't bring myself to choose between one or the other. AW tracks HR and sleep phenomenally... Garmin is set up so nicely for running/fitness, but is simply terrible at sleep tracking. If Garmin had the HR and sleep tracking of AW, it would be a very easy winner. The AW Ultra 2 is also not worth the cost for a bit of extra battery life. Guess I'll keep rocking both devices to track my metrics🤷‍♂️ I can see why Whoop is an interesting proposition since it sort of splits both down the middle... but the ongoing subscription is just too pricey.

[medinspiredbyed]

Do you have a comparison between Whoop and oura ring? I already have an apple watch, but I always liked the presentation on the apps of oura and whoop better than apples like you said

[juliuslenz]

I ordered my Whoop yesterday using your code! Thank you for these great scientific reviews! I really enjoy watching your videos on all sorts of devices just because the way you explain and compare everything is both informative and entertaining at the same time! Thank you for your great work! 💪

[iamthebest]

Attempt number two to get Quantified Scientist to review the Ringconn Gen 2 Smart Ring. He could start a Patreon or something if it's too expensive, I would donate to help him be able to buy it.

[Crsh_nd_Burn]

Hey Rob, any chance you could do a comparison between the Ultrahuman Ring AIR and the Oura Ring 4? With Oura’s subscription model, I know a lot of people are looking for alternatives, and it would be great to see how the Ultrahuman Ring stacks up in terms of accuracy, comfort, and overall performance. Thanks for all the awesome content!

[tjgphoto]

great video. Would be interested to see how Oura ring 4 compares.

[rocfella]

fitbit inspire 3 and charge 6 still best bang for buck for sleep tracking

[climbto]

Since it is the number one factor for the determination of restedness and exhaustion for Whoop, I would be even more interested in the accuracy of the heart rate variability measurement of the device!

[GWelby]

Thank you for all of your detailed amazing work. Love, Greg

[quadcoreigen]

What would be interesting for me which band/watch is capable registering IDLE pulse throughout the day somewhat reliably/accurately. I think most of the people who are wearing such device are not always interested in the pulse during the training but rather see an accurate sleep bpm or to trust the curves that are registered daily during work or idle/calm situations.
