You get what you pay for
This app looks cool but all that it does is calculating the distance between 2 points. The problem is there is completely no zoom, so you only see the maps as from outer space. It has no administrative maps, so no countries, or other named rivers/oceans. Anyway with that birdseye view I guess it would have been useless. Another waste of moneys!
