Kaeru teaches Japanese writing, grammar, and pronunciation in one app. No juggling five tools. No guessing which resource covers what. You open Kaeru and study.
WRITE KANJI FROM MEMORY
Most apps show you a character and ask you to pick the right answer. You pass the quiz and feel confident. Then you face a blank page and draw nothing.
Kaeru puts you in front of that blank page from day one. You draw each character stroke by stroke, building recall that transfers to real writing. 13,108 kanji with correct stroke order. Every character includes native audio, readings, and meanings.
iPad users: Apple Pencil turns your screen into a kanji notebook.
GRAMMAR THAT EXPLAINS ITSELF
828 grammar patterns from N5 to N1. Formation rules, context, example sentences, and audio for every pattern. Browse by JLPT level or search for a specific construction.
You read は vs が in 50 different patterns instead of one confusing chart. Particles click when you see them used, not described.
SRS THAT ADAPTS TO YOU
Skip two days with most SRS apps and you return to 200 pending reviews. The pile grows. Motivation drops. You quit.
Kaeru's spaced repetition tracks your memory for each item and schedules reviews before you forget. Strong items space out. Weak items repeat sooner. Miss a few days and the system adjusts instead of punishing you.
DAILY JAPANESE STORIES
A new story every day, matched to your JLPT level. Native audio at adjustable speed. Tap any word to translate. Grammar breakdowns for every sentence. A comprehension quiz at the end.
Stories put your kanji and grammar into real context. You see characters used, hear them spoken, and test yourself.
PRONUNCIATION SCORING
You study for months, open your mouth, and the words come out flat. Nobody corrects you.
Kaeru's AI coach listens. Record yourself and get scored on pitch accent, fluency, and accuracy. Feedback after every attempt. Fix pronunciation problems before they become habits.
JLPT N5 THROUGH N1
Curated decks for every JLPT level covering kanji and vocabulary. Each deck maps to your target exam. Track your progress toward a specific level so study hours count on test day.
BUILT-IN DICTIONARY
Search by romaji, hiragana, kanji, or English, Spanish, Korean. Every entry shows readings, meanings, JLPT level, and stroke count.
ONE APP INSTEAD OF FIVE
Grammar reference. Kanji handwriting. Vocabulary decks. Spaced repetition. Pronunciation scoring. Daily stories. Dictionary. Progress tracking. One subscription covers everything.
Stop splitting your study across a kanji app, a grammar app, a flashcard app, and a pronunciation tool you opened twice.
Who uses Kaeru: learners who want to learn hiragana and katakana. JLPT test preppers from N5 to N1. Anyone tired of recognizing kanji without being able to write them.
All features require a subscription or one-time purchase.
