Flashcards that stick. Modern spaced repetition, seven curated language courses โ€” nearly 20,000 cards โ€” or bring your own decks via CSV / TSV / .apkg. No account, no tracking. iCloud sync. CURATED LANGUAGE COURSES Each course is structured around real proficiency frameworks. Cards include audio, example sentences, and grammatical gender / tone where relevant. โ€ข French (CEFR) โ€” A1 to C2, 3,899 cards โ€ข Spanish (CEFR) โ€” A1 to C2, 3,958 cards โ€ข Italian (CEFR) โ€” A1 to C2, 4,237 cards โ€ข German (CEFR) โ€” A1 to C2, 4,133 cards โ€ข Japanese (JLPT) โ€” N5 to N1, 2,338 cards โ€ข Korean (TOPIK) โ€” A1 to B1, 1,165 cards โ€ข French Street Speak โ€” 274 cards of colloquial vocabulary native speakers actually use The French course also includes a listening-comprehension beta: audio-first cards born from the words you already know, so your ears catch up with your eyes. BRING YOUR OWN Already have a flashcard library? Import from: โ€ข CSV / TSV files โ€” including tab-separated files like those exported from popular study tools, or anything you can paste from a spreadsheet. Map columns to Front, Back, Tags. Map a header row if you have one. โ€ข .apkg files โ€” with media, sub-decks, and review history preserved. Drop the file from Files, iCloud Drive, or any document provider. Imports run on a background thread so a 5,000-card deck doesn't lock the app. Failed rows (malformed quoting, missing fields) are reported with a downloadable CSV you can fix and re-import. HOW STUDYING WORKS FSRS-5 is a modern spaced-repetition algorithm that schedules each card based on your actual recall, not arbitrary intervals. Forgetting curves shorten over time. The algorithm has 19 parameters that adapt to your specific learning history, and you can re-optimise them from your own reviews after a few weeks of use. Each language course pairs recognition (see the word, recall the meaning) with production (read the example sentence, produce the target word with full grammatical context). Production cards unlock once a word has been seen a few times โ€” so you're not blindly guessing on day one. Native-quality TTS reads cards in the target language using your installed iOS voices. Settings includes a voice setup helper that links straight into the iOS pronunciation download for each language. OCR and voice dictation are built in for card authoring โ€” point the camera at a textbook page or speak the word, and the recognised text drops into the field. SYNCS ACROSS YOUR DEVICES Decks, cards, review history, streak, achievements โ€” everything syncs through your private iCloud account. Same Apple ID, same state on iPhone and iPad. No third-party servers see your study data. A pull-to-refresh on the home screen forces a sync if you ever need it. PRIVACY No account. No sign-up. No third-party login. No tracking pixels. No selling data. We never could even if we wanted to โ€” there's nothing to sell. The aggregate product-health signals we do collect (app launch, import succeeded, review submitted) are bucketed, anonymous, and never include card content, deck names, or review ratings. You can turn them off entirely from Settings. Your decks, your reviews, your progress โ€” they live on your device and in your private iCloud database. That's it. --- Open the App Store, install, study. Built by one person who wanted spaced repetition to feel less like a chore and more like a tool.
