“Evernote Peek is a free app designed to help you study, learn and strengthen your memory. Interacting with Peek is pretty intuitive. Once you’ve connected Peek to your Evernote account and selected your study materials, you simply close the Smart Cover and peek under it to see a clue. Raise the cover further to reveal the answer. To advance to the next clue, just close the cover and repeat.” (Via Evernote Blogcast)

Such a clever idea, now I need a smart cover (and an iPad 2)
