I downloaded this app looking for a loose reference here or there. Unfortunately, any map, whether its the tiny island of Santorini or other, they charge 5$ each time! Doesnt even indicate anywhere that is the case. It looks as if it is only a one time fee, but its not. Fees for everything in this app so times 470 x 5$ each.
