Activity Log
An activity log reports key events such as the time and location of each position reported to the remote server. Tapping on the location opens and displays it in the Maps app.
Activity Log Clearing
The activity log is intended to be a temporary aid in reviewing activity whilst logging. The contents of the screen are not saved and are cleared or partially cleared if iOS reports low memory or when the app is stopped.
Generally, the app will be stopped by iOS after it has been inactive for a while. It should not normally stop whilst remote logging is active.
