Add flags (waypoints) to the map to mark your current location or other locations. Import flags from other sources using GPX files and geocache LOC files.

Useful for geocaching. MEASURE Measure the distance between points on the map. Note: Continued use of GPS running in the background can dramatically decrease battery life.
