You attach the small connected device to something that you can't leave the home without, like a set of key rings, a purse, or a briefcase. Using Bluetooth, the Fetch is paired with a smartphone and if the phone moves 15 meters (49.2 feet) away from the Fetch, an alarm goes off. A Google Map will show the last location of the phone and the Fetch device. A button on the accessory will also snap a picture using the camera on your smartphone, if it is within range.
