Also, an app is there, with an icon on the home screen to remind the user of its existence. I think this makes future use more likely than if the user just entered the address, and even more than with a bookmark that is visible only in the browser. I know the users can create the icon themselves by saving a bookmark to the home screen, but for some reason they seem not to.
