All you have to do is install it in your child’s phone (it’s up to you whether you want to be discreet about it or not) and on your own phone. After some minor configuration you’re good to go. Trick or Tracker can be set to constantly update you on your child’s location at specified intervals. You can even set the app to warn you via text if your child has exited the allowed perimeter during their trick or treating or if the kid has returned home.
Kids who are aware of the app on their phone can also let their parents know where they are or find out where their parents are. At the moment the app is only available on Android devices, and costs $4.99 but Iconosys will be making the app free on Halloween from 8am EST until 11.59pm EST. Get it from the Trick or Tracker website.
