The Find It feature is great to locate easily misplaced objects such as keys, wallets, purses, remote controls, canes and umbrellas, etc. The Anti-lost feature ties your Bluetooth low energy tag attached object to your phone/tablet. Alerts will be sounded if the two are separated at a distance on the phone/tablet, the Bluetooth low energy tag(If proximity profile is supported) or both. The Anti-lost feature is perfect in situations such as keeping any eye on your valuables when travelling or to keep track of your kids or pets from wondering off.
