Why would Logbook App like to access my location in the background?

Short answer: Logbook App is not using your location in the background as long as autorecording is not enabled. A red border around your iPhone screen indicates autorecording is enabled:
Logbook App with red border indicates autorecording is enabled

Detailed answer: Unfortunately the wording choosen by Apple is not very clear, since iOS8 Apple distinguishes between 3 different cases. Furthermore iOS8 reminds you after 2 days if you still would like to grant a app access to your location even if this particular app never used your location in those 2 days.

While Using App

This option is actually sufficient to operate Logbook App. Everything works as designed when you're in the App. However, enabling autorecording and leaving the App will show a blue ribbon on the top indicating Logbook App is still running and accessing the locatino in the background.
Blue ribbon indicating background activity


The blue ribbon is no longer visible, however Logbook App is still only using your location data in background if autorecording is enabled. Launching Logbook the first time, the App requests access to location data always. Feel free to adjust this to "When Using the App" if you've no problem watching the blue ribbon. By the way, when autorecording is disabled (no red border) Logbook App will not use any resources (CPU, battery...) in the background.

How long lasts the battery when creating log entries automatically in the background?
