The short answer

On Android, a web app (PWA) with a proper manifest can show its own Install button. But MDN says about that custom button: "This is not supported on iOS." iPhone users can still install your web app themselves: on iOS 16.4 and later, PWAs can be installed from the Share menu.

What to do

  1. On iPhone, hide your Install button and show a short hint instead.
  2. The hint: tap Share, scroll down and tap Add to Home Screen, then turn on Open as Web App.
  3. Ask your AI tool: "Show the Install button only where the browser fires beforeinstallprompt. On iPhone, show a short hint instead: tap Share, then Add to Home Screen, then turn on Open as Web App."

Good to know

  • On iOS 16.4 and later, PWAs can be installed from the Share menu in Safari, Chrome, Edge, Firefox, and Orion.
