Biostrap

2 issues: privacy and reliability. If the wrist sensor runs out of battery I can only resync auto sleep monitoring by uninstalling and reinstalling the app. Sleep data ain't be collected until I do that. No other combination of resets work. Privacy: the selection to only use GPS while only using the app will NOT allow the app to connect in spite of the app starting you can via the typical warning "may be degraded performance". Once connected using "allow any time" the setting can be reset.

I like the HRV tracking. My doctor suggested I get this so we could keep track of some trends and address some issues. My problem is with the app. I will constantly get messages throughout the day telling me to sync because I haven't done it since yesterday. Even when I did it 15 minutes prior. When I try to stop the sleep recording in the morning, it routinely locks up and says it can't connect to the wristband and to get closer to it. The wristband is on my wrist holding the phone.
