Hipocampus is a premium spaced-repetition app for USMLE, NCLEX, Bar, CFA, CPA, ANZCA Primary, Royal College and AMC candidates. FSRS-5 algorithm. Native iPhone, iPad, Apple Watch. No clutter, no ads.
Available on the App StoreHipocampus runs FSRS-5 — the current state-of-the-art free spaced-repetition algorithm by the Open Spaced Repetition team. The scheduler models difficulty, stability and retrievability for every card and predicts your forgetting curve from day one.
When you fail a card, Hipocampus uses Apple's on-device Foundation Models to explain why you likely got it wrong — based on which adjacent cards you've struggled with that week. Private, fast, and free of cloud cost.
Open Hipocampus on Apple Watch for a 5-card session while you wait for the train. Haptic feedback for correct and incorrect. A complication on your watch face shows the day's due count.
Type, draw with Apple Pencil, or speak your answer aloud. Vision recognises your handwriting; the on-device LLM grades "close enough." Recognition cards are nice; recall cards are how you pass.
Drop in an Anki .apkg from iCloud Drive. Hipocampus parses every card and template natively and reschedules them on FSRS-5 from day one.
