There are two kinds of apps that have been build and rebuilt since personal computers first emerged: Recipe card apps and flash card apps. However, the free Evernote Peek for iPad is the first one that I would consider cool. Its 2.0 update adds support for 14 languages, organizes study notesbooks into stacks and brings content from third parties like Martha Stewart Publications, 7×7 Magazine (a magazine about San Francisco) and study guides by by Magoosh, Membean and Brainscape.
Peek 2.0 Gets Quizzes from Martha Stewart, 7×7 and More. Plus, Improved Organization and New Language Support
I took it for a spin and found it delivered exactly what it promises: Lift the first segment of the iPad 2′s Smartcover to see a question. Lift it a bit more to see the correct answer. Close the flap and go to the next question. You can see a bit of this as well as the notebook organization in the screenshots below.
