@2b2bff But tracking heart rate is really the most important thing you can measure in sports. All other analyses depend on the heart rate data. If the first 10 minutes are wrong, the rest is wrong too. I also have a comparison with a heart rate strap. And if the overall average of the workout is 15 beats lower, that’s quite a lot. And as an ambitious amateur athlete with triathlon ambitions, I need to be able to rely on it, because I use AI to analyze and plan my training. And I just don’t really want to wear a strap because I can’t consistently rely on the measurements. Like I said, Garmin, Polar, Samsung, Pixel… no problem. I also don’t think the hardware is the issue.
It just has to work. Thats it.
