A senior GPS tracker is a small device that can be clipped to a keychain or worn as a pendant, letting family members know where an older adult is at all times. It helps prevent worry when someone with memory issues goes for a walk or forgets their way home. The tracker sends real-time location updates to a smartphone app, so caregivers can quickly check on the person's safety without being intrusive.
