Why most kanji apps fail

Most apps train recognition.
KanjiKanji trains recall, writing, and review.

  • You recognize it — but can't write it.

    Multiple-choice quizzes flatter you. The blank page tells the truth.

  • You forget between sessions.

    Without spaced review, the kanji you 'learned' on Monday is gone by Friday.

  • Your queue becomes a chore.

    Bloated decks turn daily study into deck maintenance, not learning.

What you get

Built for the way kanji actually sticks.

Five differentiators — not a generic flashcard deck with a Japanese skin.

Adaptive SRS

Reviews scheduled around what you almost remembered — per kanji, per recall path (meaning, on'yomi, kun'yomi).

On-device handwriting

Stroke recognition runs on the phone via PencilKit + ML Kit Digital Ink. Your strokes never leave the device.

Learn more →

Offline-first

Strokes, reviews, and progress all work without a connection. Study on flights, subway rides, and low-signal commutes.

No account required
