The app is relatively good at what it does, and more convenient on the iPad than some alternatives. The rendering of the maps seems generally rather good, however there seem to be some inconsistencies especially with the political maps. (For instance, the states of Mexico are sharply demarcated but not the states of Australia or Germany or the provinces of Canada.)
In addition, the map presently seems to have some outdated information, for instance “Mount McKinley” in Alaska instead of the correct and official name, Denali; also, it draws the International Date Line through, rather than around, the nation of Kiribati.
