JPSTrack saves tracks of where you have travelled with your GPS-enabled mobile device. It is mainly intended for those who wish to contribute map data to OpenStreetMap.org, the free editable map of the world.
Note that JPSTrack is not a traditional "navigation" app; it will not show you maps and it will not help you find your way! It can only record where you have been. There are lots of other navigation apps in the Market, please use one of them if you want to find your way around.
