gps tracking for elderly

My dad forgets where he is sometimes, so we got him a small GPS tracker that clips onto his belt. It lets us see his location on a simple map from our phones, and it even has a fall detection alert. Now he can walk to the park without us worrying, and he feels more independent knowing we can find him if he gets confused.
