Maplender is simple map viewer. I allows to view maps in following formats:
* TrekBuddy map
* TrekBuddy tared map
* TrekBuddy non-tared atlas
Aplication also can show user location on the map, and store user track in GPX file.
List of supported map datums: WGS 84
Note: continued use of GPS running in the background can dramatically decrease battery life.
