With a Tile Bluetooth tracker, you can easily find your valuables. You simply attach a tracker to your key ring, laptop, wallet, or backpack. When you lose something, you can activate an acoustic signal in the app to hear where the object is. There are different types of Tile Bluetooth trackers, each with their own purpose. The Tile Mate fits your key ring, the Tile Slim in your wallet or on your laptop, and the Tile Pro has the largest range.
