You're Welcome to Make Feature Requests

You may make feature requests on Flyspray at OpenCPN.org. Yeah, the name is definitely strange, but that's the place where requests are acknowledged.

The Cruiser Forum is the place to discuss OpenCPN. However, its not the place to post feature requests. The development team only monitors Flyspray to prioritize requests. Thanks for your input.


*The Software and the App for Android are Separate Things

To help shed light on this confusion, its important to understand that the software and the app are different.  The software program is free, the official Android App is a purchase for a small fee.
