Math Train (数数小火车) is a playful maths-practice app for young children, roughly ages four to seven. Each journey is a short set of addition or subtraction problems within 20, wrapped in a friendly train theme with stars, stamps and a mistakes notebook to revisit. It works offline and lets a grown-up tune the difficulty. The interface is in Chinese.
