Alminav: Offline Outdoor Navi

Alminav is designed for hikers, cyclists, and other outdoor enthusiasts. One of its main advantages is that it can function offline, as signals in the rural areas are often very weak. Maps can be downloaded in advance, and are vectored so as to not take up a lot of space in the phone's storage. Navigation works offline with downloaded maps.

RECTANGULAR MAP TILES
The map tiles are all the same size and cover the rectangular area from one longitude and one latitude. Example: The tile n48e005 covers the area between the latitudes north 48° and 49° and between the longitudes east 5° and 6° (area about 100x100km). These tiles have a small download size, the route calculation is fast, they cover large parts of Europe.
For the area of Germany, marked cycleways can be displayed in the 3D view.
