Flashcards
The smoothest way to study on iPhone and Mac. Build decks, review with swipes, and actually remember things — powered by FSRS, the most accurate spaced repetition algorithm available.
Built for people who actually want to learn.
Not just a card flipper. Flashcards uses FSRS — the state-of-the-art spaced repetition algorithm — to figure out exactly when you need to see each card again. Study less. Remember more.
FSRS Spaced Repetition
Rate each card across four difficulty levels. The algorithm tracks your memory stability and schedules reviews at exactly the right moment — not too soon, not too late.
Silky Smooth Gestures
Swipe to rate, tap to flip, tilt your phone for a subtle 3D card effect. Every interaction feels physical and responsive — studying is actually enjoyable.
iCloud Sync
Your decks live in iCloud and stay in sync across iPhone, iPad, and Mac automatically. Start a session on your phone, continue on your Mac.
Streak & Session Stats
Track your review streaks and see a breakdown of how many cards you nailed vs. struggled with each session. Momentum builds motivation.
