Online flash card web application Cramberry creates simple flash cards in an easy to use, clean interface—great for memorizing boring study terms. Using the web application requires creating a free account, after which you can build sets of cards in a single-lined, text-only, question-and-answer style. When using the cards in studying mode, Cramberry will repeat cards that you get wrong for extra practice. The sets can also be shared with other users, although there's no place to publish a public list of cards for others to browse, so you'll need to know a username to share with—but the clean and simple style makes this worth a look for anybody trying to memorise facts for class. Cramberry is a free web application, signup required.
