Been using OpenCPN for a couple months now. It’s basically a full-featured chart plotter and navigation app for your phone. Pretty solid if you’re into boating, sailing, or just exploring maps.
Here’s what you can do – you can view detailed nautical charts, plan routes, and even track your position in real-time. And there’s also a handy chart downloader so you can use it offline. And the vector chart support is pretty cool, you get all these advanced navigation features.
Look, if you’re into navigation apps or just love messing around with maps, you’ll probably like this. It’s not perfect – the UI can be a bit clunky at times – but overall it gets the job done. Worth checking out, especially since it’s free.
