Read full descriptionHide full description
Learn to write Japanese by hand: kanji, hiragana and katakana, with correct stroke order and instant feedback on every stroke. Kanji Write teaches you to write Japanese stroke by stroke: over 2,000 JLPT kanji plus all hiragana and katakana. Practice with your finger on iPhone or with Apple Pencil on iPad, and build real muscle memory. โ Correct Stroke Order Every character is animated stroke by stroke and color-coded, so you learn the right order and direction from the start. No guessing, no bad habits. โ Instant Feedback Each stroke you draw is checked against the correct shape and order. Miss a few times in Guided mode and a hint appears automatically. โ Trace. Guide. Memorize. Three practice modes: trace over the character, follow the strokes one at a time, then write it from memory with the guides hidden. โ Hiragana & Katakana All 46 basic kana in both scripts, plus the voiced forms (ใ, ใฑโฆ). Search by romaji: type "ka" to find ใ and ใซ. โ Complete JLPT Library (N5โN1) Filter kanji by JLPT level, search by meaning or reading, and see on'yomi, kun'yomi and meanings for every character. โ Built for Apple Pencil & iPad Pressure and tilt shape every stroke like a real brush. On iPad, practice in a notebook-style grid, like a calligraphy workbook. โ Quick Sessions Tap play for a random set of characters from any level or script and review your results at the end.
