I have a Polar H10 and I wear a Polar FT4 (watch) that receives the signal and I download the recorded data to Polar Beat app on my iPhone 11. Consistently my FT4 shows I burn more calories than my Polar Beat app even though the duration, Max HR and Average HR a the same (or close to the same). Any ideas why that would be?

This is great! A meticulous data scientist finds useful research about heart rate devices and summarises it for us. I am especially pleased that the H10 performs so well, as I bought one on Rob's recommendation. I also got a Polar Verity Sense, and this compares very closely with the H10 and is very useful for long cycling trips. This idea of Rob's to review research in his inimitable way is very welcome!

Then i tried to put it on my abdomen area, it gives a surprisingly consistent result compare to putting on the chest. I wonder if you are intrested in testing the actual accuracy diff of the H10 on various locations on the torso or even on legs.

I dont know how much it costs there in your country but in mine we can get it for $20 shipped to our doors. I truly appreciate your work, cheers!

[@brayan8346]

I had the new HRM pro and hated it. It’d constantly disconnect from my Apple Watch and my Epix Pro. For some reason it also wouldn’t connect to my treadmill. A few months ago I bought an H10 and returned it immediately as I seemed to get a faulty unit. I got another one yesterday. It works perfectly with all of my devices and my treadmill. I’m really happy with it also the band is much more comfortable than the Garmin, with the HRM I messed it up in less than a month of having it.

[@noneims]

Great video! 👍🏻 I wanted to ask which signal standard is better to use from H10 - ANT+ or Bluetooth, or is it irrelevant? (I've tried to find it before, but no success, thus concluding the latter one) And which signal do you use in your testing?

[@jeffw654]

I have decided to go with the Verity Sense because the chest straps could cause chafing (especially when wearing a running vest). It took a while to find a spot that gave a consistent signal, but now it seems great. It is hard to measure accuracy without measuring it against something else at the same time but I think that it is accurate and consistent enough to show my progress.

[@orangeofmars2835]

What app do you use for ECG with Polar H10. I have an iPhone and it seems no apps available for ECG with Polar H10.

[@AquilaTheHun]

Hi Rob, I have owned a H10 for 2 years and have a question. In theory, it is supposed to be moisted before strapping on. However, I noticed no difference in accuracy (well, not scientifically testing it of course) dry vs moisted (I used ECG/US gel and water or own saliva). As for the ECG testing, I use Polar Sensor Logger app (Android) and sometimes the ECG curve was pretty erratic (noisy) in the same movement free position of course but sometimes beautifully drawn. I was wondering what might cause this (moisted vs dry, cold vs warmed up (by body heat)). I couldn't really figure it out. Once I even purchased a new strap thinking that the old one got worn out or something. These days I don't bother to moisten it just put it on. Any thoughts on this? I can send you screenshots to illustrate. For HRV I use Elite HRV which detects signal quality which is 99 percent clear. As for the results, I cannot verify them of course. But it's very detailed , all the HRV components are shown.

Hi, thank you for all your great work and hours you are putting in to bring us such a valuable content. Recently I stumbled upon some content about Fitcent HR monitors, I searched and found several very positive user reviews regarding its accuracy, but also a price. Since it is really a budget HR strap, at least compared to H10 and likes, I think it would be a good idea to test it sometime in near future. There are some of us who would sacrifice a percentage or two of accuracy for a 2 or 3 times lower price of HR strap, if that sacrifice in this case necessary. :)

[@SF-li9kh]

Can you get hold of a holter ? Would that help with your ECG variability comparison with Apple, Samsung, Fitbit ECG testing. Only these watches offer ECG features

[@MMAFightMagazine]

Thank you for the great work and valuable content you're producing! 😊 Regarding this study, I can't help but have some concerns that I wonder if you might consider addressing? If the study suggests that the H10 outperformed the holter based on the definitions employed into the algorithm; doesn't this tell us that something about the algorithm "favors" the output of the H10? I have my H10 on right now, and I'd love nothing more than to see it performing AS WELL AS the gold-standard holter; but to see results that suggest that it's significantly outperforming the holter is problematic for me. I feel that all but "proves" that the algorithm used favored the H10 in those very specific regards, as opposed to determining overall accuracy. Perhaps an issue with relying on using the R-R interval to detect the three error types as mentioned at 5:03 ? I'm not sure. I don't know if I explained my thoughts properly, but I'll have to read the study myself. May I ask if there were any apparent conflicts, financial or otherwise?

[@mlegrand]

I also need some participants in a research study to clean up after my kids here at my house 😂 What I've found is that most of these heart rate straps on the market (even the very very affordable ones) are extremely accurate when testing for running. The errors tend to be when there's not a good connection to the chest but using a little electro gel is the way to go! Was that part of the testing protocol for this study?
