Sooner or later your kids will want to go out by themselves. Maybe to a friends house, a day trip/excursion, or to a party/night club.
You don't want to discover that something bad has happened only at 2am when your son/daughter still hasn't arrived home.
With FamilyGuard, you can setup "Check points", so that your son/daughter can "check-in" at one or more points throughout the day. For example, if your son goes to a party which finishes at 1am, you could setup "check points" at 23:00 and again at 01:00.
FamilyGuard will send messages to the childs phone to "Check-in". If there is a problem and he/she fails to check-in, then FamilyGuard will alert the parents (everyone on the "emergency contact list").
