We may still be waiting for Penguin's beautiful childrens' book-reading iPad app, but if you favor their Classics range, this free annotated listing app will be a nice companion to that battered paperback you always carry around.
It basically acts turns any Penguin fan into a card-carrying Penguin fan, with descriptions of each book; quizzes; a profile for listing all of your read books; plus a neat shake-to-discover function so you can read something the app chooses at random.
Unfortunately the app fails at letting you download ebooks, though it does direct you to the Penguin shop where you can buy paperbacks or hardbacks. It's a free download, and was added to the App Store only yesterday. [iTunes via Fast Company via Future Blog]
