Common questions

Shu marked something that looks right to me.

Tap the word in the margin to see why. If Shu was wrong, the menu beside Next lets you change the grade. You can also choose Pen strictness in Settings, which marks order, direction and shape but not stroke endings.

Can I write with my finger?

Yes. With a finger, Shu reads endings from speed alone, so it starts at Pen strictness. Apple Pencil gives the brush its full range.

What are tome, hane and harai?

The three ways a stroke can end: a firm stop, a flick, and a sweep that lifts gradually. Japanese teachers mark all three.

How do I restore Shu Pro?

Settings, Shu Pro, Restore purchases. Use the same Apple Account you bought with.

How do I cancel?

In the Settings app: your name, Subscriptions, Shu. Cancel at least a day before it renews.

Where does the data come from?

Stroke order from KanjiVG; meanings, readings and words from KANJIDIC and JMdict; JLPT levels from Jonathan Waller's lists. Shu's adapted stroke data is shared under CC BY-SA 4.0. Full credits are in the app under Settings, Sources and licences.
