We strongly discourage the use of TrackR on cars, pets or people. TrackR uses Bluetooth technology to connect your items to the TrackR app on your phone and does not use live GPS technology. Once the TrackR is outside of Bluetooth range of a user’s phone, the TrackR app will show the Last Seen location of the TrackR. This is the last location where the TrackR and TrackR app were connected. The TrackR app does not track minute-by-minute movements of a pet, car, or person when it is outside of Bluetooth range. For a complete explanation of how TrackR works, please check out this article
Additionally, the volume of TrackR’s ringer may cause your pet discomfort.
