Deena wants to track her family with her iPhone. Leo says that a smartphone has GPS, an always on internet connection, it's designed to be a surveillance device. Always remember to have permission of the person you're tracking. For the iPhone, there's Find My Friends. There's also Life360. But her husband's phone is on Android, so how does he keep track of their son? Google Maps will let you share your location. Open Google Maps, tap the blue dot and select share location. It will time out after awhile though. That's the best option because it's free and cross platform.
