One-button install
In Chrome and other supported Android browsers, the Install button can trigger the native install prompt. After that, the shortcut lands on the phone home screen.
Phone-ready web app
Install this site so it opens like an app.
This uses the phone's home screen shortcut and standalone display mode so the page launches without normal browser bars when the platform supports it.

Browser preview
Launch behavior
Looks like an app icon. Opens like an app window.
Once added to the home screen, tapping the icon starts this page in a browser-powered shell with the regular browser chrome hidden.
Installable

iPhone
Manual add to home screen
Safari on iPhone does not allow websites to force-install themselves. The user must tap Share, then Add to Home Screen. Once installed, it still launches in standalone mode.
Important limit
This is the web-standard version of a phone app shortcut.
It is not a full native app package. It is a Progressive Web App, which is the correct approach when you want a website to feel like an app without showing the usual browser UI.
