Kora is a flashcard app that schedules reviews with the SM-2 spaced-repetition algorithm. Build image or text cards, paste multiple cards at once, organize decks with colors and icons, and review progress through streaks, heat maps, and statistics. The U.S. App Store listing describes offline study, export, and syncing through a personal iCloud account; it lists all features as free with no subscription. A Japanese App Store listing also describes generating cards from notes, photos, and PDFs with on-device Apple Intelligence, but that feature is not shown on the U.S. page and may depend on storefront and device. Apple says the developer reports no data collected. Kora requires iOS 26.2 or later, which is higher than many flashcard apps.
