Study smarter, not harder. Flashcard uses the SM-2 spaced repetition algorithm to show you each card at the exact moment you are about to forget it. Whether you are preparing for an exam, building vocabulary, learning a language, or mastering any subject, Flashcard adapts to your pace. HOW IT WORKS Rate your recall after each card: Again, Hard, Good, or Easy. Flashcard automatically schedules your next review. Cards you know well are pushed weeks into the future. Cards you struggle with come back the next day. Over time, you retain more while studying less.
