Recallity doesn't quiz you on what you already know. It finds your gaps, then drills them with real recall — not multiple choice. Most study apps test recognition: four options appear, one looks familiar, you tap it, and you feel productive. Exams don't work that way. You retain what you're forced to produce from memory — not what you merely recognize. Recallity is built around that difference. HOW IT WORKS 1. Upload your material. Lecture PDFs, photos of handwritten notes, or pasted text — Recallity reads it and builds an outline of every topic inside. 2. Brain dump first. Before a single card is generated, you go topic by topic and mark what you actually know: "Know it", "Shaky", or "No idea". No wasted reviews on things you've already mastered. 3. See your knowledge map. AI compares your brain dump against the material and shows exactly where your gaps are. 4. Drill with real recall. Recallity generates fill-in-the-blank and typed free-recall cards targeted at your gaps. Your typed answers are graded by AI in seconds — including partial credit and an explanation of what you missed. 5. Review on a schedule that works. A modern spaced-repetition engine (FSRS) brings each card back right before you'd forget it, so every session counts. BUILT FOR EXAM CRUNCH • Exam Mode — set your exam date and Recallity compresses your review schedule so nothing lands after the test, with a readiness status that tells you if you're on track or behind. • Tap to see the source — every AI-generated card links back to the exact passage in your material, so you can verify and re-read in context. • One more look — miss a card and it returns a few questions later in the same session, while it still stings. • Smart Notes — an AI summary of your upload, so you can review the big picture before drilling the details. AND MORE • Progress insights: streaks, weekly activity, and per-deck stats • Study in 11 languages, including Spanish, Chinese, Arabic, Portuguese, Japanese, and Vietnamese • Confidence ratings that tune your schedule to how well you really knew the answer • A dark, focused design with no ads and no clutter WHO IT'S FOR Students cramming for finals, med and law students drowning in dense readings, language learners, certification candidates — anyone who has limited time and needs what they study to actually stick. Stop re-reading. Stop recognizing. Start recalling. --- Recallity is free to try. Recallity Pro unlocks a much higher daily deck generation limit, available for $6.99/month or $39.99/year. Payment is charged to your Apple ID account at confirmation of purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings. Privacy Policy: https://recallity.app/privacy Terms of Use: https://recallity.app/terms
