To add the map as a web clip to the Home screen on an Apple iPhone or iPad, tap
in the browser toolbar, then tap
Add to Home Screen. On the next screen that appears, edit the web clip name (if desired) then tap
Add to add the icon for the map to your Home screen. Doing this allows you to run the map in the same way as any application: by tapping its icon on the Home screen. When run like this, browser toolbars no longer appear so the map will occupy more of the screen and will be easier to use.
Similar techniques for adding the map to the home screen are also available on Android devices.
