RecallDeckStudy

RecallDeckStudy turns study time into lasting memory. It combines classic flashcards with the proven Leitner spaced-repetition method, so the cards you struggle with come back often and the ones you know return right before you would forget them — the most efficient way to learn.
Everything works completely offline. There are no accounts, no ads, and no tracking. Your decks and your progress never leave your device.
WHY RECALLDECKSTUDY
• Spaced repetition that works. Every card lives in one of five Leitner boxes. Recall a card and it moves up a box and returns less often; miss it and it drops back for extra practice. Your review schedule adapts automatically.
• Learn by feel. Tap a card to flip it, then swipe right for "Good", up for "Easy", or left if you forgot — or use the buttons. Rating your recall is what powers the schedule.
• 100+ cards, ready to study. Eight built-in decks get you learning in seconds: World Capitals, Science Basics, Spanish Vocab, History Dates, Math Formulas, Biology, English Vocab, and Geography.
• Build your own decks. Create custom decks, pick a color and icon, and add as many cards as you like.
• See your progress. A mastery gauge, a weekly review chart, and a live view of your Leitner boxes show exactly how your knowledge is growing.
• Stay motivated. Day streaks, mastery milestones, and achievements keep you coming back.
• Truly private and offline. No sign-up, no internet permission, no data collection. Study on a plane, on the subway, or anywhere else.
