Been using BackCountry Navigator GPS PRO for a couple months now. It’s basically an app that lets you download offline topo maps and use your phone as a GPS navigator for hiking and outdoor activities. Pretty solid app if you’re into that kind of thing.
Here’s what you can do: you can download maps for the US and other countries ahead of time, so you don’t need cell coverage when you’re out in the middle of nowhere. There’s also support for Android Wear, so you can see your navigation on your smartwatch. And you can import GPS waypoints from files or just enter coordinates manually – that GOTO feature is useful for navigation.
Look, if you’re an outdoorsy person who likes to explore off the grid, you’ll probably like this app. It’s not perfect – the map downloads can be a bit clunky sometimes – but overall it does the job. Worth checking out if you want an offline topo mapping solution.
