My Tracks This app is easy to use and packed with more features than most will ever need. This is a great app for walkers, joggers, hikers, bicyclists etc.... Turn on your GPS and let it follow your tracks. Mark spots along your way with the Waypoint feature, (This is great for long and winding trails you may have been on; you can leave yourself reminders of difficult locations, etc...)and keep track of not only your distance and time, but your elevation and speed as well. Love this for the Bicycling season!
