Great app!! I needed to find some new hiking trails and heard about this app from a friend so I downloaded it. There are so many trails I have never even heard of that I found through this app. The tracks are very useful when I go off trail so I can easily find my way back. Since most of the trails I hike on have no cell service I absolutely love that I can save an area on the map, before I leave service, and have it anywhere I go!! Life saver!!
