A Tile is an easily recognizable visual shortcut for an app or its content that users can set in the phone's Start view. Which Tiles show on the Start screen can be customized by “pinning” an app’s Tile to the view. A Live Tile is better than an icon, because it can surface info about or relevant to the app. For example, a Tile for a weather app can dynamically show the temperature. We strongly encourage you to take advantage of this feature because it makes your app that much more useful.
