"After a year or two of tinkering and experimenting with apps for teaching / learing Geography, I have (finally) compiled this list of what I deem to be the most useful iPad apps for teaching Geography. I have not rated any of them, or offered any kind of review. I have merely inserted a screenshot or two and a link to the App Store. The discerning down-loader is urged to consult the ratings and reviews for each of these before buying and downloading them. I like them, and I am sure that you and your students will too."
