鯉躍龍門 · KOINORI

Sound Japanese,
not just read it.

Most apps teach you to recognise words. Koinori teaches you to say them, with real-time pitch-accent feedback no other app gives you. Read graded stories, mine sentences in a tap, and watch your koi leap the Dragon Gate as your Japanese matures.

The difference

Hear your own pitch

See and correct your pitch-accent in real time. Perception drills, a live contour you can match against native speakers, and scored practice on words and short phrases. The thing every other app skips.

Read real Japanese sooner

Graded, comprehensible-input stories with one-tap furigana. Always slightly above your level, never out of reach.

Remember it for good

Reviews scheduled by FSRS, the modern spaced-repetition algorithm, so you study the right card at the right moment and nothing slips.

鯉 → 龍

A pond of koi that become dragons

Each koi is a part of your Japanese: kana, kanji, listening, pitch. As a koi truly matures it leaps the Dragon Gate and becomes a dragon in your garden. Progress you earn through real competence, never points for showing up.

Help shape Koinori

We're building this for people the other apps let down. Two minutes of honesty here directly shapes what we build.

1.Which languages are you learning or want to learn?
2.Where are you right now in Japanese?
3.Which apps have you used?
4.What made you quit or feel stuck with them?
5.How much do you care about sounding natural - pitch and pronunciation?
6.What's the one thing you wish a Japanese app did well?
7.Would you pay for an app that nailed that?
8.You'd mainly use it on...
Optional. Every question can be skipped.
