Let this app take care of tracking your favorite trails as you go along them. Mark places of interest on the map along the trail created by the app and share them on facebook if you wish to. You may even share the complete trail on the click of a button.
Use retrace mode to travel back on a trail already created before.
This app records your GPS locations periodically when you press start trail button. The information is stored only in your phone and not on our servers. When you explicitly share your trail information only then the information is moved around on the internet.
