TrackR pixel is a small, colorful Bluetooth tracking device that easily attaches to all of your important items. You can use the free TrackR app to ring your item in seconds, and the LED lights on the pixel will flash to help you locate it. You can also use your TrackR pixel to ring your phone, even on silent mode! If your item is lost outside of Bluetooth range, TrackR’s Crowd GPS network can help you recover your belongings. When a TrackR user is within range of your lost item, you’ll receive a location update to your smartphone.
