Recall is a modern flashcard app built on the science of spaced repetition. Powered by the FSRS-4.5 algorithm, it schedules your reviews at precisely the right moment - just before you'd forget - so you retain more while studying less. Whether you're revising for GCSEs, learning a language, preparing for medical exams or mastering any subject, Recall adapts to your memory and builds a study plan that works. BUILT-IN GCSE LIBRARY Revising for GCSEs? Recall ships with a ready-made library covering 22 GCSE subjects - Maths, Biology, Chemistry, Physics, English Literature, History, Geography, languages and more - with proper maths notation and real curriculum content. Add a subject and start studying in seconds. AI DECK GENERATION Paste your class notes and Recall's AI turns them into a ready-to-study flashcard deck in moments - one testable fact per card, with maths notation and code formatting preserved. Review, edit and save the cards, then let FSRS take over. Free users get 3 generations to try; Premium unlocks unlimited. SMART SCHEDULING WITH FSRS Recall uses the Free Spaced Repetition Scheduler (FSRS-4.5), the most accurate open-source spaced repetition algorithm available. Unlike fixed-interval systems, FSRS models your actual memory patterns and optimises review timing for each individual card. The result: better retention with fewer reviews. CREATE YOUR OWN DECKS & CARDS Organise your knowledge into decks and cards. Add front and back content with full Markdown support - perfect for code snippets, formatted text, lists and more. Import existing material or build your collection from scratch. FOCUSED STUDY SESSIONS When it's time to study, Recall presents cards that are due for review. Rate each card as Again, Hard, Good or Easy and the algorithm adjusts the next review interval accordingly. Cards you find difficult appear more frequently; cards you know well are spaced further apart. STREAKS & MOTIVATION Build a daily study streak to stay consistent. Your streak tracks consecutive days of completed reviews, helping you build the habit that makes spaced repetition so effective. Streak freezes are available so a single missed day doesn't break your momentum. KEYBOARD SHORTCUTS Power users can fly through reviews using keyboard shortcuts. Rate cards, flip them and navigate without touching the mouse. Every second saved adds up over thousands of reviews. OFFLINE SUPPORT Study anywhere, even without an internet connection. Recall works fully offline using local storage. Your cards, decks and review history are always available on your device, and changes sync automatically when you're back online. CROSS-DEVICE SYNC Sign in to access your flashcards across all your devices. Create cards on your laptop, review them on your phone. Everything stays in sync via secure cloud storage.
