Seemed to work well initially but stopped working on my son's phone which was the whole reason for using it so we could track his location. Kept reporting he was still at school at 10.30pm even though he was next to me at home. Even though he received my requests to check-in and I could receive those check-ins I still had to remove him from the circle, re-invite him and reboot his phone to get it showing the correct location. If something happened and he was missing I wouldn't be able to remotely reset his phone, would I? Unreliable piece of garbage app. Delete at once!
