Trick or Tracker is a trick-or-treat app that allows parents to monitor their children's location as they wander around the neighborhood in their scary little costumes. The app is compatible with both iOS and Android smartphones, and was developed by Monster Arts, which specializes in family safety, lifestyle and entertainment apps.
The app allows parents to locate their children either on demand or at pre-set check-in intervals, while enabling children to locate their parents or send them messages. The app uses a daytime satellite map for location capability.
Parents can also set a specific perimeter and receive notifications if the child wanders beyond this perimeter. They can even program pre-set destinations like home or school and receive notifications when the child arrives at said destination.
The app can be purchased for $4.99 from iTunes, Amazon or Google Play.
