To find a missing item simply tap on "Scan" button and scan the area of your bag or room with a swipe of a hand. It is best to hold the Dongle close to your phone. All the items found will be checked with a V mark that they're in place. If an item is missing (marked with “X”) you can tap on it, and GearEye app will guide you to your lost item using graphics and sounds like in the “Hot & Cold” game
