Add To Home
Add to home is an extension which encourages your mobile users to put your site on their home screen as a shortcut. There are many options you can use to modify it.
The script opens an always-on-top message inviting the user to add the application to the home screen. This is currently supported on iOS and Mobile Chrome. While other devices have the ability to bookmark any website to the home screen, only iOS and Mobile Chrome have a straightforward way to do it.
