The World by National Geographic

Maps have lost some of their sexiness these days, but The World by National Geographic manages to make them fun again. The app is a geographical educational tool, but it's loaded with bright pictures (a trademark of the National Geographic Society's magazine), interesting facts, and an interactive map that is a lot of fun to play with. You'll learn a lot and have fun doing it, which is a difficult combination to pull off for younger kids.

The app falls a bit short, though, for anyone who is a regular user of Google Earth. Instead of being able to zoom into territories as you can with that app, The World stops short, transitioning to a paper map appearance. It's a minor frustration, but given how deep you can go with other apps, it's a bit disappointing not to have that option here. The reliance on an Internet connection is an annoyance, as well, but all-in-all, this is a great app.
