Here are a few ways to keep track of your kids when they're trick or treating on Halloween.
Family Signal for iPhone shares your child's location and comes with a panic button for emergency situations.
You can also set up a [UNKNOWN] with the trickle trace route then get an alert if your child leaves the area.
LifeSign offers similar functionality but for Android devices.
You can also track the battery life and the ringer status of your child's phone.
Track & Treat by Glimpse is a Halloween themed app that lets you see where your kids are in real time.
Install it on your child's phone, enter your email address or number in the app, then it sends you a map with their current location.
If you'd rather track Halloween locations in your suburb, the next door app has a treat map.
Neighbors can tag their house with a candy corn, or a haunted house icon to show they're taking part.
