This application will allow the user to find out how far it is to a certain point.  It was developed for Rowing coaches, to be able to understand distances from where they are to another point, in order to plan/execute a workout.  You can quickly find out how far it is from your current location, to another point.  You can then continue to add points/markers.  The app will keep track of the total distance of the path you created (display can be in meters or miles). Additionally, each marker can be selected to show the distance from the previous marker.

Lastly, the markers can be moved - simply press-and-hold a marker, and drag it to a new location.
