Flips: Just-in-time Flashcards 4+

Flips is a flashcard app designed to help you review just in time, before you forget. Based on the forgetting curve and powered by Spaced Repetition (SRS), it automatically shows you the right cards at the right moment so you can learn faster and remember longer. Perfect for vocabulary, exams, certifications, or any subject that requires memorization.

Main Features
・Just-in-time review (SRS)
Cards appear automatically at the best moment: mastered cards are shown less often, while those you might forget come back sooner. This makes your learning efficient and effective.

・Simple and fast learning
Launch and study right away. Swipe, tap, or multiple-choice—minimal interactions optimized for focus.

・Visualize your memory
On the home screen, a clear chart shows learned, forgotten, and unstudied cards. You’ll always know what to do today.

・Build a streak, build a habit
Your study streak is displayed like a calendar grid. Watching your progress grow day by day motivates you to keep going.

・Forgetting gauge & levels
Each card has a “forgetting level” so you know exactly what to prioritize next.

・Create & import decks
Make your own decks in minutes. Import from CSV/TSV files or export from other apps.

・Smart reminders
Get notified when it’s the best time to review—so you never miss the optimal moment.

・Text-to-Speech (TTS) support
Hear correct pronunciation and practice listening as you learn (language support depends on your device).
