app crashes after upgrading to 2.32

Please update to V2.33 (available in App Store)

I would like to post my Logbook to Facebook, is this possible?

Yes, you can post your Logbook from your iPhone or iPad directly. Please see the HOWTO post a Logbook to Facebook.

Can I use the App on multiple devices?

Yes, the easiest way to copy the database to another device is open the app on the source device, go to Tools, Export, end select SQLite. Send the file via Airdrop, Email, or iMessage to the target device and open it there with logbook app. Read this iCloud article to understand why it's not possible to use live iCloud synchronistation.

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 blue (in older versions red) border around your iPhone or iPad 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.

Logbook App has no access to your location as the operating system does not allow access for Logbook App. You will face this message every time you open Logbook App:

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 to record the track in background-mode?

Make sure that you have activated autorecording in the settings menu. A red border around the app appears, when autorecoring is active. Now your track gets recorded according to the selected distance setting. You can also enable/disable this feature by tapping the GPS position on the home screen:

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

Our experience with an iPhone 7+ have shown that the battery lasts for a full day (12 hours) and remains enough battery for the evening. However we recommend to carry either a 12V charger, or a power bank with you.
