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 application has a lot of nice features but on a tablet it has some issues compared to the PC version. It has gotten better since I started using it in 2020. Something I would like to see is the ability to remove charts in a way that actually deletes the files. I accidentally downloaded all of the NOAA MBTiles and now would like to delete the Pacific ones but you can't and the Android blocks access. I don't want to use the clear data function in Android and lose all the data.

Night mode still missing on this chart plotter. It is a must have feature for every chart plotter to be use during night navigation. Please add...

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.

The latest update appears to have removed the option to display my stored US RNC charts. As the ENCs don't show inland waterways (like the S Gulf Cove entrance to the lock and route to the four boatyards near Placida, FL), I'm forced to transition back to Navionics. I wish the Android version had at least the same capability as the Windows version, as I'm not going to keep a laptop in the cockpit. Additionally, the celestial nav tool won't run in Android.
