Great app. Tracks are nice and simple. Export to google earth, or *.gpx format. This is nice for later import into mapping on pc, or GE on the iPad.
Only complaint: I wish you could toggle on or off the auto streaming map image. When on 4G, map streaming can eat up valuable data plan quickly. So, turn off 4G before launching this app.
