" As such they might be less appropriate for long-term data collection, similar to chest straps." The glue on ecg are a hassle but they are also designed to be worn for at least a day .All those formal medical devices like the Zeo zio? are "stick it on for a week" glue ecg probes. Chest straps are designed to be worn for the length of an exercise period like two hours. Chest straps are also worse to wear to sleep. How long is long term? Certainly not like chest straps.

: That's a good point, I guess it's conflating 2 types of long-term: "Over-night wearing" and
"doing it every day" (where the latter would maybe be annoying with the glue-based solutions". I'll try to clarify the wording on that! - [[User:Gedankenstuecke|Gedankenstuecke]] ([[User talk:Gedankenstuecke|talk]]) 12:31, 1 July 2022 (UTC)

In other words the difference between what the heart rate user is experiencing under exercise and what they should be is very important information and the device pawns off the first as the second. The difference should be pretty obvious if user does exercise that does not involve moving the relevant arm. Lot of devices do this with other sensors and then defend their dishonesty with words. They should not be allowed and there should be a page all about it!

: I'm not sure I fully understand. You mean that in some cases there's no actual PPG readings and it just uses the accelerometer-data to make a guess for the heart rate? Do you have an example of that? I know that most wearables that use PPG take movement into account but rather in order to remove the noise/artifacts that are introduced in the readings as a result of moving the arm. In that case I wouldn't say it's 'guessing'? - [[User:Gedankenstuecke|Gedankenstuecke]] ([[User talk:Gedankenstuecke|talk]]) 12:31, 1 July 2022 (UTC)
