About this app

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.

FEATURES

• Spaced repetition that adapts to you — rate each card Again, Hard, Good, or Easy and Flippi sets the next review automatically
• A 10-minute relearning step for cards you miss, so they come back in the same session
• Practice mode to drill any deck without affecting your schedule
• Track your progress — daily streak, cards due, and a 14-day review chart
• Start instantly as a guest — no account required
• Create a free account anytime to back up your decks and sync across devices (sign in with Apple, Google, or email)
• Clean, distraction-free design with full dark mode
• No ads. No tracking. Your cards are yours.
