Phone Halo TrackR System
Running late and can't find the keys? Phone Halo's TrackR system can help avoid that frustration. The system works by pairing a TrackR smartphone app, which works on iOS and Android devices, with small, discrete TrackR devices. The devices themselves can be attached to commonly used items such as car keys, wallets, purses or luggage. Then, as long as those devices are within 100 feet of the phone, the TrackR app will hunt them down.
