Tile is a Bluetooth Low Energy device that connects to the iPhone to assist users in finding lost items like keys, wallets, computers and more. The company is offering Tiles for $19 each via a Kickstarter-like preordering process. The company has more than 18,500 backers and just passed $1 million in orders with 7 days to go. The device uses Bluetooth LE to connect to supported iPhone and iPad models. If something with a Tile attached to it is lost -- car keys, for example -- the iPhone can show you the last place it remembers seeing the tile, and can also make the tile play a sound via a built in-speaker. If something is lost or stolen, the system will have other Tile devices look for it and report back on its whereabouts.
