Yes, they do. There are watches available with GPS trackers in them. They were recommended to us by home health care when my mother-in-law came home from memory care rehab. She's not to the point where she needs one yet, but the nurse told us that they are available on Amazon and probably through other sources as well. I did a very quick online search and found several options including some with geo-fencing which means you would get an alert if she leaves a pre-determined zone. Hope that this helps.
