Navigation client that uses OziExplorer maps (ozf2, ozfx3). Great for hiking, geocaching, off-roading, sailing, boating and other outdoor activities. You are expected to be aware of OziExplorer or at least of where to get its maps. Maps also can be created by yourself, but with some afford, see FAQ for details.

If you are a developer you can request pulls, of course. You can fix annoying bugs or have a look at the road map.
You can also write a plugin for Androzic.
