The most relevant one to A2HS is the splash screen displayed when the app icon on the Home screen is tapped and it first starts to load (this currently appears only when apps have been added to the Home screen by Chrome).

(Note: In Android 8 and higher, a system-level "Add to Home screen" permission dialog will be shown first.)

Tapping this will show a confirmation banner - pressing the big + ADD TO HOME SCREEN button completes the action, adding the app to the Home screen. You'll see fox pictures, but more important, you'll see a "home" icon with a plus (+) icon inside it - this is the "Add to Home screen" icon displayed for any site that has the necessary features in place. If you have Firefox for Android available, use it to navigate to our demo at.

The example displays a series of fox pictures. We've written a very simple example web site ( see our demo live, and also see the source code) that doesn't do much, but was developed with the necessary code to allow it to be added to a Home screen, as well as a service worker to enable it to be used offline.
