Want a quick route to a website that you visit daily? You don't have to enter Safari every time you want to access it -- instead, turn that website into an app that you can access from your home screen. To do this, visit the page in Safari and tap the menu button at the bottom of the screen (it looks like a rectangle with an arrow coming out of it). Select the button that says "Add to Home Screen" and give the app a name.
