Flippi

Flippi is a clean, fast flashcard app for remembering what you learn. Make decks, add cards, and let spaced repetition bring each one back right before you'd forget it.

Built on a proven spaced-repetition algorithm (SM-2), Flippi schedules every card for the moment review matters most — so you study less and remember more.
