The basic app does what it states, but could be better. It would be nice to have a help button/directions on how to best use the app instead of learning by trial and error. The button/status notification takes up too much screen space and there seems to be a dead space around the edge of the map that does not respond to screen touches. The undo button is Wonky as sometimes I have to hit it 30 times to remove a short extension, other time the undo remove the past 1/2 mile or mile extension.
Once the route has been mapped, it would be nice to have an export ability to Strava or Garmin.
