- Open the site link in Safari. It has to be Safari, because Chrome on iOS cannot install it. And if you tapped the link in WhatsApp, you are in its built-in browser: tap the share button or the three dots and choose Open in Safari first.
- Tap the Share button, the square with an arrow coming out of the top.
- Scroll down the list and tap Add to Home Screen.
- Tap Add. The icon appears with your other apps.
- Open it from that icon from now on, and sign in from inside it. The installed app keeps hold of your sign-in far better than a browser tab does.
- Open the site link in Chrome. If you tapped it in WhatsApp, tap the three dots and choose Open in Chrome first, because the built-in browser cannot install apps.
- Either tap the Add to home screen button in the site’s own toolbar, or use the three dots in Chrome → Add to Home screen / Install app.
- Confirm. The icon appears in your app drawer.
On a Samsung phone, install it from Chrome rather than Samsung Internet. Samsung’s browser builds the app for an older version of Android, and Google Play Protect blocks it with “Unsafe app blocked”. Nothing is wrong with the app or your phone: open the link in Chrome and install it from there.
- Open the link in Chrome or Edge.
- Click the install icon in the address bar, a small screen with a downward arrow at the right-hand end. Or use the three dots → Cast, save and share → Install page as app.
- It opens in its own window and pins to your taskbar or dock.
On Safari for Mac: File → Add to Dock. A plain bookmark works fine on a computer too, since the week-long expiry is an iPhone problem.
Signed in on your phone and not installed yet? Home offers it, in a card headed Get notifications, and stay signed in, and so does You, under On this device. Where your browser has no install button of its own, the button says Show me how and opens the steps.
