Conclusions: Overall, the Apple Watch is by far the best heart rate tracker for the Apple ecosystem, and the Huawei Watch GT Runner is the overall winner on android. For instance the Whoop 4.0 and Garmin Instinct 2 also did a good job here. Now, if you want the best battery life out of a device, and pretty good heart rate tracking during cycling, then I would recommend the Garmin Instinct 2. If you just care about heart rate tracking, and you do not need a smartwatch, I would just buy an ECG chest strap, like the Polar H10, which will give the most reliable results.

I have multiple reasons for thinking this is not the case, the most important being: (1) I can still see that the Apple Watch does better during "easy" types of workouts than during "hard" ones, which shouldn't happen if it "hacks" the H10 (2) I connected 2 out of the 3 apple watches to different phones than to which the Polar H10 is attached (3) The correlation is not 100% perfect, and I still see small deviations Thanks for the suggestions!

@stephendenagy3396 Жыл бұрын

I am a physician and came across this. This is very good! I personally noticed that the Apple Watch didn’t used to seem to correlate well with my Polar strap. But now with Watch 7 it seems spot on. Rare anomalies, like sudden spikes that the Polar did not catch, suggesting error. Very useful! Allows me to leave the Watch on as my main driver. Would be nice to keep adding to the database with time. Especially as the newest Apple Watch, the Ultra, is now released. As it is so focused on sports, would be nice to compare to other high end triathlon and ultra watches. Also, I have always wondered about SaO2. There seems to be such a wide variation. In the day, from low to high 90’s. Makes no sense. I have always felt the the high SaO2 levels are likely accurate, and low values doubtful, what do you think? Great work!

Great summary. There was no such comparison of HR accuracy in the network, especially with the division into the exercise category. Now we are waiting for the same tests but in the GPS accuracy category. Recently, I tested the Apple Watch 7 and Huawei GT Runner and I am impressed with the high accuracy of AppleWatch GPS tracking e.g. a run in the forest. I noticed that the smartwatch from Huawei does not "collect" data as quickly in the field as the Apple Watch. By making quick turns during the run or turning perpendicularly, the AW7 does it really impressively precisely, where Huawei can "round" the perpendicular turn and cuts a few meters from the turn. In total, Huawei lost several hundred meters from the 5 km test on the route.

Thank you so much for this video. I bought Fitbit Sense two weeks ago so i can track my heart rate during weight lifting. Result - it was never showing it above 109bpm no matter what, only on my cardio days i was able to see 117bpm which is still not reallistic, i should've watched this earlier. Short story is after watching this video the other day since i am not Apple guy, i bought GT Runner and that nailed it. I am able to get accurate heart rate readings again during weight lifting, average 130-150bpm during workout is completely different story. I wasn't aware threre are issues for most devices to get accurate readings during weight lifting. Thank you so much again. And thanks to my wife for taking the Sense so i can buy the Runner :).

Hi thank you for the amazing work you do. I had a query. If i was to track my workouts with a chest HR strap paired to the Strava app. the calorie burn recorded will be basis ONLY the heart rate recorded ? or will some algorithm based estimates also be used (like the wrist based trackers use) ? is there anyway to track calorie burnt purely by heart rate data when pairing a chest sensor to an apple watch/garmin venu/samsung watch 4 ? thank you

Fantastic review. A subscriber of mine suggested I transition to correlation of coefficiency calculations like you did here, versus the analytical approach I take. I think these results do a much better job at how it truly approaches it analytically so I am going to shift future tests to that! It will help add a different type of sports training assessment to the optical tests alongside yours as I do all analytical tests while doing CrossFit. Thanks again - great work

@Qbyte248 2 жыл бұрын

What is you current method of calculating the accuracy? I think the standard deviation of the error (sqrt(MSE)) could be a better indicator than correlation since the correlation neglects scalings and biases.

@fitgearhunter 2 жыл бұрын

@@Qbyte248 hey! Mine is rudimentary- first I cut off the bottom half of the HR numbers of the chest strap and the same number of beats per minute of the test device, then run percentage of accuracy of the two numbers - inverting the percentage when the test unit is above the chest strap (ie 108% = 92% accurate for that one point). And then average the numbers. I’ll have to look up how you do what you are talking about. Thanks!

@Qbyte248 2 жыл бұрын

@@fitgearhunter Why do you cut off the bottom half of your measurements? Are there accuracy problems? You might want to look into en.wikipedia.org/wiki/Geometric_standard_deviation (and en.wikipedia.org/wiki/Geometric_mean) which is better for relative values and at the end "invert" the percentage.

This is the only video reviewing that say’s Apple is the best yet marathon triathlon all say Garmin all the reviews but yours is this a conspiracy theory. Lol it’s all good I respect your opinion it’s valid I just don’t know if it’s right like I said 99% sure and Apple only works well with Apple that’s how they make their money that’s why it’s still a lighting port instead of usb c, but I guess they make the best charging system as well. But again I respect your opinion I just don’t agree with it.

Amazing video! Apple once again running away with it as expected. They have the best smartwatch by far that also doubles as the best fitness tracker. Only issue is the ~1 day battery life. That's too short for me. I also just use a my almost 5 year old polar h10 ecg strap for heartrate. Looking forward to the sleep tracking analysis! I got used Fitbit charge 4 for about $40 about a year ago and haven't been disappointed. Still looking forward to the new Xiaomi S1 watch when that rolls around to western markets as it doesn't run a full blown os so it should be able to get ~1 week of battery life. Hope its fitness tracking is ok. That's pretty much my only concern. Otherwise I'll keep waiting for whatever google comes out with whenever they get around to it. It's been almost 2 years google! Come on!

I really like the idea of someone objectively analyzing this, but I really would've liked to see a bit more of information beyond just this correlation index: - how did you build such index? - despite not correlating so well, how did the devices do in terms of variation? I.e. it could be off the ideal in a reasonable manner, did you take that into account?

Great video, hope this video will make it to wide audience to give pressure to manufacturers to make better and more accurate products knowing their sales will depend on it. This video is such important service to all of us as a customers. With enough financing (to compensate watch purchases and your work-efforts to analyze data if that would impact it), it would be awesome to have wider test pool, including more tech nerds to participate data gathering with serious mindset to produce high-quality data based on the same exact methods you've used. I would think for data gathering one could find enough volunteering and suitable candidates, but not sure how many would have means to buy all the products on their own on top of the data gathering work. Additional people could make the tests even more significant to wider masses, maybe help gain more awareness, but not sure if there is any financial model to keep it sustainable

What are some hypotheses for the garmin venu 2 very good outperformances of others within the garmin sphere? Could there be any luck involved? Where it was worn? EG with multiple watches worn at once and some closer to your wrist and some closer to your elbow?Software updates? Watch size? The sensing hardware is the same as you say. For me my venu 2s performs very poorly as compared to my pulse oximeter (Nonin) or just simply measuring my pulse with my finger on my neck and a stop watch! It's worst when excercising as compared to being at rest.
