OK, now going on ice chest #4. Latest one stolen from Cheek's Marine. Second one that's been stolen. I feel like killing someone.
The Tile iOS app (not yet available) allows your to find a Tile by telling you how close you are to it. You can see yourself getting closer and further away from the Tile when within a 50 - 150ft range via the iOS app. The app logs the last location it saw your Tile (via GPS) giving you a good starting point. Tile also includes a built-in speaker, so you can make it emit a tone when you're getting close.
But it's the Tile service that makes it compelling. It uses a crowd-sourced model so that you still have a good chance of finding your Tile (when it's attached to a dog or your MacBook, for example) even when it travels out of its 150-foot (Bluetooth) range. It's like having the world help you locate your lost item. You can track a Tile by seeing when it's identified by other Tile users.
