"Tile finds whatever you’ve lost, if you’ve stuck one of the little white Tile squares to it. Each Tile pairs with an iOS app, so when the item goes missing, you can use your Apple device to track it down. But that’s just the beginning. The company is planning to build a community of users, any of whom could track down your item if it goes missing in public."
