Tried to use this today to track a car trip. In one hour app crashed 12 times. Each time when bringing the app back up, it said it was still tracking, but it wasnt. Had to stop track and restart. If crashing could be addressed, I like the simplicity of the app. One other more minor annoyance is the amount of screen real estates devoted to the stats while tracking, would prefer a full screen map.
