Why Do My App Settings Change When I Log Out?

Some app settings are stored by user session alone and will revert to the default options when you log out of the app. These settings include voice feedback, units of measurement, coaching, Bluetooth device connections, live tracking, and more. You must remain logged in to keep these settings in place each time you utilize the app. 

Remaining logged into the app will not result in a battery drain unless there is a workout actively recording. Force quitting the app will allow you to remain logged in while ensuring that the app is not actively recording or using battery life.
