I love being able to use official chart files for navigation. Worlds better than Avionics for basic navigation like making routes and seeing tracks. But I would love a few improvements to some issues I have: - Tracking stops when the screen is off. I use a separate GPS tracking app for that part but would like to use OpenVPN. - Ordering tracks by start date doesn't happen when I press the "start date" column. - Import GPX only works sometimes.

Mostly works really well and has a lot of functionality. The UI can be awkward to use on Android phones though as I think it was originally designed for larger screens. I have the UK charts from o-charts, which are good value, but the ones for Greece are pricey for the 1 week a year I might go.

This app feels clunky and dated... that's made worse by the lack of availability of open charts. I regret purchasing the app.

The APP is very slow and keeps crashing with only UK map installed on the latest Android 14 / Samsung S22 Ultra. I am using the o-chart plugin. Moreover, during every start, it is complaining that it can not access some folder, so when I finally clicked on it to migrate, then the map for which I paid for has disappeared. Another problem is that license is assigned only to this phone. Generally speaking, it is very complicated to use and works very slowly. I am thinking of asking for a refund.

It is unreliable. It regularly crashes and loses access to its files. This has been going on since the beginning. I love OpenVPN on my laptop, but not my Android
