How can I export a dog trail?

1. Open a dog-trail and click on the menu (three points on the top right corner) and choose ‘Export as…’
2. In the following dialog choose ‘GPX’
3. Wait until the export has finished
4. Now choose the App to share the created GPX file
5. Alternatively you can choose AirDrop to send the GPX-file directly to your Mac. (Info: sending via Airdrop from iPhone to a Mac only works if the Mac is younger than 2012)
