Active Recall turns what you're studying into flashcards — and schedules every review for the moment you were about to forget. WHY IT WORKS Of the ten study techniques reviewed in the research literature, only two earned top ratings for effectiveness: retrieval practice and spaced repetition. Active Recall is built on both, and nothing else. No quiz modes, no matching games, no word games — just the recall loop that actually moves things into long-term memory. Reviews are scheduled by FSRS, a modern spaced-repetition algorithm that models how your memory for each individual card decays, and learns from your own review history. The more you study, the better the timing gets. MAKE CARDS WITHOUT THE CHORE • Hand it a page of notes, a PDF or a photo and get a drafted deck back • A fast, keyboard-first editor for when you'd rather write them yourself • Cloze deletion (fill-in-the-blank) as a first-class card type • Cards stay organised in decks and chapters, so big subjects don't sprawl STUDY IN MINUTES A DAY • Five focused minutes clears a typical day's queue • Streaks, a forecast of what's coming, and progress charts that show real retention • Cards you already know stay in rotation, just spaced further out — dropping them is the fastest way to forget them YOURS, EVERYWHERE • Sign in with Apple or Google and your decks, streak and review history follow you to any device • Works offline — study on a plane, sync when you land • Full support for light and dark mode, Dynamic Type and VoiceOver • Available in English, Spanish, German, French, Italian, Portuguese, Japanese, Korean, Simplified Chinese and Hindi PRICING Active Recall Plus is a subscription with a 3-day free trial: $3.99/month or $24.99/year (prices may vary by region), auto-renewing until cancelled. It unlocks everything — unlimited decks, chapters and cards, AI card generation, and FSRS-scheduled reviews. Cancel anytime in Settings. No ads. Ever.
