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.

Promises much but disappoints. It leaves one to believe that data (Routes etc.) can be created on Windows PC and transferred to your Android tablet for use on the boat. My experience is that this is not possible and despite raising this with developer on several occasions I have not had a reply. The navigational functionality, I have yet to test.

Alas,.why is it so hard to get the appropriate charts? This app clearly has great functionality, and I desperately want it to work for me. But I've spent hours trying to get the correct ENCs or raster charts to download and show properly (uncluttered labeling, objects stay visible with zooming in and out) on my Android 10. How in the world to make this functional? I tried to register for the user forum but the confirmation email never came.

Fantastic app, integrates with all charts and is very easy to use. I am withholding one star only because I can't get it to work with my Vesper XB8000. I configure a TCP network exactly as instructed and with the correct (default) settings, but nothing. Meanwhile my watchmate app is reading the ais info perfectly - only without the map and all. If anyone can help me with this, I'd be grateful!

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.

Superb, I've been a user on a mac for a long time and only in the last few days installed this on my android tablet - works brilliantly. Where else can you get a fully functioning chartplotter like this? Thanks to you and all of the team - your work is very much appreciated. Pretty sure the grib file download issues will be resolved soon, but other than that, like it a lot.

App frozen. Needs to update database and then just hangs on black screen. sent an email to developer who doesn't answer. I want my money back.

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.

So far, all of the functionality is working well. I switched from Navionics Boating when they got greedy and doubled the annual cost. I should have switched earlier - OpenCPN is much more powerful! My key complaint at this point is not being able to get access to the support forum for app purchasers. It never sent the authentication code.

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 licence 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.
