I think it's a great APP – Trail Tracker GPS - Running, Hiking, and Cycling Review

I use this for biking and walking. The settings are great and it's easy. You just open and hit start. Then when finished hit finished. The graph is cool and shows all the hills you hit while riding. I wish it had a route planning tool in it. If it did I would give it 5 stars.
