Study your own notes with an offline flashcard library, spaced review, and mock exams. NEW IN 3.0 Search deck titles, questions, answers, and tags. Export a portable deck-library backup through Files, preview a restore, and preserve the previous library before replacing it. Recover unreadable deck, review, or exam-history files explicitly without silently discarding their originals. STUDY YOUR WAY Use flip-and-grade, multiple choice, typed answers, cloze cards, tags, and custom study sessions. Spaced review uses FSRS-based calculations with app-specific learning steps. Exam Lab builds repeatable practice exams with results and confidence comparisons. Exam Countdown shows model-based recall estimates, not a validated prediction of your exam result. CREATE FROM NOTES Import screenshots or PDFs for on-device text recognition, use CSV/TSV, or enter cards by hand. Compatible Apple Intelligence devices can generate cards with an on-device language model when available. Otherwise, or for longer material, labeled rule-based generation selects usable notes. Check generated cards against the original sources. YOUR LIBRARY Included starter decks cover selected geography, arithmetic, elements, language vocabulary, units, roots, geometry, and music topics. They are introductory study aids rather than complete references. Edit cards and tags, keep review activity, and export decks. BACKUP AND IMPORT DETAILS Deck backups include cards, tags, exam dates, and card schedules. They exclude review history, exam results, reminders, and preferences. Restore replaces the whole deck library after preserving the previous file; separate histories remain unchanged. Backups and recovery exports are unencrypted. Backups: up to 25 MB, 2,000 decks, and 20,000 cards. CSV: up to 10 MB and 20,000 cards.
