My mom has been asking me these questions about her apple watch like most former fitbit users she tracks her day the number of step she takes and has been finding it very hard to adapt to calories burned instead (we know steps are also available but no way to set goal) She has a physical job (mail lady) so she tends to turn on the activity tracker in ether “outside walk” or “other” mode. She does her full shift on that mode, i obviously told her this was not how it was meant to be used because that’s her “regular day” and not extra activity activity (green bar). My explanation sounded like this “activity tracker leaves the heart sensors ON instead looking every five minutes or so”...”if you tell your watch you are working when you are in fact between adresses your messing up your stats”....”plus in drains your battery so much” Her response was “no matter if it reads my heartbeat every five minutes or every second I shouldn’t be getting such big differences in my activity rings by just switching “ON” on the activity mode, if it reads my heart more often because its always on it should realize i’m at rest until I get physical again.” “My reading should be similar whether or not activity ON or not” Which sounds like a fair point. I was without arguments I told her i’d look it up. So who’s right me or her? How would you put it simple for her? I’m out of arguments.
