What are users saying about OpenCPN

by Z####:

Love opencpn on laptop and Raspberry pi 3 All my attempts so far to install charts on Android version have failed, CM93 Phone Wileyfox swift. Free version and this paid for version same result , point charts at folder containing charts and app becomes non responsive. Initial 1 star updated to 5 star, after checking on forum discovered it read/write privileges on Android needed amending. Thanks for link Dave

by A####:

Happy to have the sanctioned OpenCPN Android app. Streaming all sorts of NMEA data to/from a Raspberry Pi 3. Comforting redundancy. All I have to do now is get off the dock and go cruising.

by R####:

I have used thus on my laptop and pc and it is brilliant BUT when I try to load charts on my galaxy 4 and galaxy 5 there is nothing. I notice a few other users can Not load charts to their phones either. Any help or tips would be appreciated.

by J####:

Links to my boat WiFi NMEA multiplexer and provides instrument panel wherever I am on the boat.

by Y####:

Works great on my Lenovo tablet and my Samsung S4 phone.

by F####:

Brilliant app,, works very well and links straight up with my inbuilt gps(samsung s4). very accurate and just needs a few more of the plugins to make it identical to the pc version. One small problem i have is the text appear/disappear button is not on the top(or anywhere) ofthe text stuff on the map cant be seen....any ideas developers please.

by C####:

An essential addition to any yacht, I can't imagine sailing without. Plus there is endless support through the forum if you run into problems, though it's so intuitive I can't image even a beginner would need much help. Additionally buying this version as opposed to installing the free version encourages the developer to continue the good work. Also running the exact same software on my tablet, phone and laptop is awesome.

by E####:

Have been using PC version for years so I paid for Android version to support developer and give something back. BUT cant upgrade from 1.08 to 1.09, says device is incompatible even though it is same device. Read a few posts with same problem, tried to register on forum but did not receive activation email. Yes i did check spam as recommended, so nowhere left to post to inform developer. maybe related to google play store, however I'm left with a paid app that i cant upgrade. UPDATE: ver 1.0.10 is compatable again with my Blackberry, must be the 'Disable USB Host mode compatibility filter.' that did it - Thanks Dave. Excellent support. Excellent App.

by N####:

Intuitive interface and nice to have readily available

by H####:

Great as a backup for the Garmin Chart plotter.

by K####:

As of now I had several captains attempt to download a map. I have tried for several hours. Your manual does not address this, only how to do this on a laptop. At this point I nearly have all the instructions memorized. Can you give me detailed, specific to a nexus7 instructions? If this is not going to work, I am requesting a refund as it is not stated the app will not function on a Nexus7. Preferably, a fix. /////Update Accurate and specific instructions were provided by Dave. So far working fine. Upgrading to five stars because of service.

by O####:

Was excited to see opencpn on android as have been using on pc for years. Installed and downloaded NZ charts specified the directory but have been unable to display charts. What am I doing wrong. On samsung tab2 10.1. Used chartdownloader. Loaded nzcharts sameway on s4 works good. Tried to use bigdumboat forum but wont send activation code. Getting frustrated.

by X####:

I bought this pay version because I could not figure out how to pair with Garmin Glo Bluetooth GPS on the free version. (FREE version also available on Google Play. But even the paid version could not be paired to the Bluetooth GPS, despite the details provides BLUETOOTH remote GPS support Program too small. Tried on A Samsung S6 edge Phone. Near impossible to change settings due to small layout not showing all fields. Depth too small to read, even after zooming in, the Depth indication gets tiny to read Needs more work, before paying for it. Why is there a FREE one that appears to be identical? I really wanted this to work as a backup to my Laptop and Ipad, but more work needed.

by P####:

Need detailed operational tutorials. Check out those of Paul's for GE2Kap. Specifically for installing and accessing charts would be extremely helpful. All the locals here have been having no success with charts.

by M####:

Installed on asus zen pad okay and instantly recognized the internal GPS. It refuses to recognize the cm93 charts I have been using on PC laptops for years. Also there is a few seconds window of opportunity to select between raster, vector or cm93 when the app first boots. Then the option disappears and can't be brought back. Lastly, the help file appears to reprinted from the Windows version and isn't useful. I uninstalled the app. Too bad, it's great on the old laptop.....update, I stumbled onto the solution. My cm93 files were corrupted in transfer somehow. I should've compared the size of the transferred files to the original to make sure they were the same. Now open cpn is as wonderful as always. The raster,vector,cm93 menu appears as needed when an area is covered by more than one chart format, therefore it's a non problem. The help page could be much better and the support forum is inaccessible to me, but the app itself is great. Therefore I'm piling on the stars...

by B####:

Crashes really regularly. Auto detect for com ports does not work so I cannot connect my AIS like on I can on the Windows version. The only difference between the free and paid version is the dashboard plug-in. Oh, whoopie! I should have stuck with the free version until the developers get their act together.

by Q####:

Easily found the built in GPS receiver and my cm93 charts, then was up and running. Look forward to using it for real.

by Y####:

App just aborts on my Nexus 9 / Marshmallow

by U####:

bought the app as I have it on pc. but was expecting to have uk charts with it. so please can someone tell me where to get them hi dave I have cm93 charts on my pc. paid for your app for my android tablet. but have now charts with it. any help appreciated

by V####:

Can't get ais data through USB/ Bluetooth

by D####:

Pls help me how to download the philippine maps...can anybody pls try to help me...thank you.

by W####:

Working well would like the Grib plungin added

by Z####:

Works great. Connected to a RTL-SDR dongle over TCP (for AIS) with no issues.

by A####:

I am so impressed! Admittedly, I only just installed it but I've put it through its paces, doing all the things I'd normally do with openCPN on my PC, and it's all there, working and very responsive. It's nice on my Nexus 6, but now, I'm going to buy an android tablet just for this app. Thank you!

by R####:

Now our Samsung S4 Cellphones and Notepad can run routes using the onboard GPS. A very compact and inexpensive solution and a great asset in the cockpit. Looking forward to getting Nmea data on the tablet which O wiill do once I get wifi on board. Thankyou!

by J####:

This is an amazing first release of the Sailors' favourite charting application. Get yourself a copy of CM93 charts, or any of the other supported formats, and you are away. And for a fraction of the cost of nasty Navionics with their annual subscription for out of date and inaccurate charts. I am enjoying the high resolution scans of paper charts for my area (Philippines) in KAP format - the most accurate available. Sat pics also display perfectly. Performance is amazing, almost never crashes. Most of the PC functionality is working already, and doubtless more to follow. Works beautifully on both my tablet and phone.

by Y####:

I have been an open cpn fan for a while now. I used an old version of Max Sea for many years. Now open cpn is my primary software.

by F####:

Dependable, users friendly and totally free!!!have used it on board sub to ECDIS. Working great on my TAB S. Hey Dave! No AIS display on my TAB

by C####:

When I zoom in it confidently covers my home port with the map legend... not worth the time or money...zoom in on Cockrell Creek off the Chesapeake just south of the Potomac to see the effect. ..

by E####:

Great . But Where I can find the charts ?

by N####:

It takes a bit of work to get charts to display but worth the effort. Not giving 5 stars because of lack of plugins and poor documentation.

by H####:

Thanks to all the developers and testers too. 5 Stars if I could select the Auto-Follow Boat button then move my boat to where I would like on the screen. Look ahead mode doesn't cut it especially if I am rounding a headland or similar and besides the screen jumps around too much especially in a rough sea.

by K####:

It runs slow on my Sony tablet. The free computer versions seems to work better. I will update my review after using it for awhile.
