My wife and I have been using Footprints for over a year now to track our two kids. It took us quite a while to configure the app and indeed customer service didnt really help. But once we figured it out, we were able to add many locations (fences) and now we get notifications whenever our kids arrive/leave home, school and all their activities. Its also pretty accurate and doesnt waste too much battery. We just renewed our subscription for all 4 of us for two years ($5.99 if Im not wrong). I had issues with the renewal and it charged me 5 times, but I just called Apple Customer Service and got my money back right away. It turned out I had to uninstall and reinstall the app and then it worked like a charm. To my best knowledge its the best app that keeps track of the kids whereabouts out there. So dont get discouraged if its hard to set it up or if customer service is not good. Its worth using it once you go through the hurdles.
