Looking for App where I can select miles per day.

I use Delorme Street Atlas - and pick a direction and plug in a trial destination that I know is way further out than I want to go. The route preferences let me specify distance per day or miles per day, so then I start looking around that one day point. Then if necessary, move the trial destination in another direction.

Or, if I know where I want to wind up - plug in that final destination and then pick intermediate stops based on time or distance.

Street Atlas is Windows software - needs a laptop or Windows tablet.
