TrackR Item Trackers work with the TrackR app, which you can download for free on your iPhone or Android phone. TrackR devices use Bluetooth® to communicate with the TrackR app. The location of your TrackR devices is constantly updated using Bluetooth and your phone's approximate location.
If your TrackR device is out of Bluetooth range (100 - 110 ft., depending on the TrackR device), you can see its last known location in the TrackR app. If you still can't find your item, Crowd Locate can help you track it down.
