In this major update, you can now name and save up to 5 different locations. Set the start location at your car, or the start of the trail, or the subway stop and find your way back easily without looking at a map. The app shows the straight line direction and distance (as the crow flies) to which ever of your saved locations you specify.

As this app is intended for outdoor use, satellite signals inside buildings are usually weaker and can be inaccurate.
