Get the app
Put the Game Centre on your Home Screen. It opens like an app, without the browser's bars. It's the same site, so there's nothing to download.
- Open this page in Safari: copy the link, then paste it into Safari's address bar.
- Tap Share . If you don't see it, tap ••• first.
- Choose Add to Home Screen. Scroll down the list if it isn't showing.
- Tap Add.
The Home Screen app keeps its own settings, so you may need to pick your team and league again.
