InkDojo
Learn to write Japanese kanji — stroke by stroke,
the way it's actually written.
Real brush-stroke feedback
Most apps only check stroke order. InkDojo's tracing engine understands how each stroke should end — the stops (tome), flicks (hane) and sweeps (harai) that make handwriting look Japanese.
JLPT-level courses
Start from JLPT N5 and work upward through curated sets, with meanings and readings alongside every character you write.
Reviews that arrive before you forget
A spaced-repetition system schedules each kanji just before it fades, so a few minutes a day keeps everything you've learned writable.
