Does Apple Watch record data from external HR sensor when off wrist?
Hi! I'm thinking of buying a Polar H10 HR sensor to go along with my Apple Watch (Series 3) to get accurate HR readings. My use case is martial arts so I can't wear the watch on my wrist when exercising (but wearing the HR chest strap is okay). Currently, with no external HR sensor, I've noticed the Activity app pauses when I take the watch off my wrist. So in future, when using an external HR sensor, I'd like to have the HR data to be stored in the non-pausing Activity app of the watch even if the watch is inside my gym bag (within the Bluetooth range). So the question is: does the Apple Watch Activity app record HR data from an external HR sensor when the watch is off the wrist?
