simple GPS plot tracker ????
 

Can anyone tell me if there is a simple GPS app that allows one to possibly save a coordinate and plot it on map with a simple touch? What I mean is , if I wanted to record my location , say every 20 ft or 100 ft while walking , is there an pp that can do this simply, and by possibly just a simple one touch click every time you want to record the coordinates or position, so that you could go back later and see your precise path ?
