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.

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.

Does okay as a standalone chart plotter but cannot import GPX files where all other Android chart plotters have no issue. I use OpenVPN on my computer to create my routes and then import them into Aqua Map.

This version caused me grief trying to add my charts, harmonics files and routes. It was difficult to specify path and when I 'poked' the app folders and added my harmonics files I could see the files in the settings but the app froze when the file was added. I eventually got it to add my harmonics files by clearing the app cache first. The same thing happened with routes GPX file, cleared cache and routes imported ok.
