About this app
Your phone becomes a Japanese calligraphy practice book. A hand-built brush engine turns your stroke speed into living ink - draw slowly for bold lines, sweep fast for dry-brush texture. Trace authentic stroke skeletons from the Eight Principles of 永 through foundational kaisho characters, get graded on shape and stroke order, and climb the ranks from Novice to Master. ■ Features - Speed-responsive brush rendering with ink bleed and flying-white - Animated models with stroke-order numbers for correct writing order - Instant grading: shape overlap x stroke order, dojo ranks - Practice streaks and a 14-day progress chart - 100% offline. No account; all data stays on your device ■ Pricing Every lesson is free - from the complete Basic Strokes course (including 永) through all kaisho characters and the gyosho intro. The bottom banner ad can be hidden forever with a one-time "Remove Ads" purchase ($0.99, no auto-renewal). No subscriptions. From today's first stroke toward beautiful characters - with Sumi Keiko.
