Reviews for OpenCPN

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

The apps is very big file which my android find difficult to run so is it possible to remove the Chart of North and south America and Africa because I’m using only in the Philippines

This latest version freezes the movements of the boat until I zoom or pan. it was working fine with the version before.

Better transfer of waypoints, routes, tracks to/from desktop would be nice. Otherwise app and desktop are great.

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

AIS targets seem not always to show static data when expected when a Raymarine plotter using same data source has and targets remain yellow. NMEA debug window has gone so I can’t see if AIVDM messages are arriving. Would appreciate putting NMEA debug window back.

I used to like this but i got a new pixel phone, installed opencpn, can’t get charts, and help will not load because it “does not work with your phone”. to me this means they are not keeping up to date with Android (help docs posted on 2018). update: i did find the user manual […]

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 […]

New to sailing and chart plotting, but I’ve been pleased so far. On a race last night, I navigated and tracked our sail while another on board with Navionics ended up with an incomplete tracking log (iOS issue with app sleeping it seems). I’ll update review as I use more features. Oh, and I was […]

I work on ships and enjoy following along the chart on my phone, my only issue is when there is no signal it stops tracking. I assumed it would use my phone’s GPS? Anyone know if it’s just me, or does it require a signal? Other than that can’t beat the price, just takes awhile […]

This is a good app that I have been using for while. It is generally stable. Support is a bit tricky, the support forum doesn’t appear to have been updated for years. I was unsuccessful registering and getting activation emails. The Android version needs the ability to delete chart files. You can’t do this through […]
