Kado is a spaced repetition flashcard app that helps you learn and retain knowledge effectively. Choose between two proven review algorithms — the classic SM-2 or the modern FSRS, which uses a scientific memory model to schedule reviews at the optimal time for your recall rate. Customize algorithm parameters per deck to match your learning style.
Create your own decks or import existing Anki (.apkg) files. Split large decks, track your progress with learning stats, and review with text-to-speech support. Sync decks to an ESP32 companion device for offline study.
All your data stays on your device.
