Accessibility

• Every button and tap target is at least 48 pixels, and the entry pad sits within reach of one thumb.
• Light, high-contrast colours by default for sunlit classrooms, a dark mode, and four text sizes (More → Language and text size).
• Everything works with a keyboard, and with a screen reader: each tap is announced (“Q3, Asha: C”), and charts have their numbers in text beside them.
• Colour is never the only signal: right and wrong also show as letters, ✓ and ✗.
• Motion is kept small and stops when the phone asks for reduced motion.
• We test every screen with axe against WCAG 2.2 AA. Automated checks find only some problems; if something does not work for you, please tell us.
