I could have used Peek when I was studying for my Cisco Certified Network Associate (CCNA) certification. It's a simple app that allows you to make your own flashcards, turning notes into study materials. You can prepare for a quiz or learn a language. Presumably all your study materials are in Evernote so moving them into Peek is simple. Peek is not only for students. Evernote's slogan, after all, is "remember everything." Peek also could be used to prepare for a presentation in stages or to rehearse for an interview where you want to appear prepared and off-the-cuff.
