Many people use Fitbits as fitness trackers these days, so you may be wondering if you can also use the device as a GPS tracker. While some Fitbits do use GPS tracking to route your activity during exercise, it is not the same as a GPS tracker designed to share real-time location updates for a child’s safety. For example, if your kid goes out for a run, you can view her route upon her return. However, you would not be able to use the device to receive real-time location updates or geofencing alerts.
