  1. Open your favourite app screen in Safari.
  2. Tap the Share button (a square with an upward arrow) at the bottom.
  3. Tap “Add to Home Screen”.
  4. Check the name and tap “Add”.

In Chrome

  1. Open your favourite app screen in Chrome.
  2. Tap the Share button on the right of the address bar.
  3. Scroll down the menu and tap “Add to Home Screen”.
  4. Check the name and tap “Add”.
