Great value. My previous chart plotter app is no longer available on Google Play. When I got a new phone I needed to find a new app. I am really happy with OpenCPN. For $10 you can can get an app with all the updated charts you want, for free. I also like the idea that I can build something with the same user interface using free, open source software and a Raspberry Pi when I want a more permanent installation.

The weather routing does not work, and interface is very sensitive. Uses defaults for creating routes and not what I select. Using GRIBS from external apps cannot be imported since OpenCPN locations are obscured from Storage Explorer. Not very user friendly. How do I get a refund?

There is a bug in the latest version, OpenCPN doesn't see .GPX files in the /downloads folder. The work around is to rename the .GPX file to .JPG and then it will see and import the file properly. This work around doesn't work with the Samsung Galaxy Tab.
