Install the English for kids app
The app opens engforkid.com full screen, just like an app: exam practice, past results and feedback — no app store needed.

iPhone / iPad (Safari)
Tap the Share button (square with an up arrow) → "Add to Home Screen" → "Add". If you opened this in Zalo / Facebook, tap ⋯ → "Open in Safari" first.
