SHU: WRITE KANJI
Fact sheet, October 2026

Shu is a kanji writing trainer for iPad and Apple Pencil. You write each character in an ink that behaves like sumi on paper, and when you lift the Pencil a teacher marks the page in vermilion, the way a Japanese calligraphy teacher marks a practice sheet: a ring round the stroke that stopped where it should have flicked, the flick you should have made, one word in the margin. Then you write it again, right. Every kanji you master earns a vermilion seal in your seal book.

What it marks: stroke order, stroke direction, shape against the form taught in Japanese schools, and how every stroke ends (tome, hane and harai: stop, flick and sweep), read from the Pencil's pressure and speed. Never a variant Japan's handwriting guidelines accept, and never more than three marks on a character.
