With Zones, KidGPS sends you push notifications when your KidGPS enters and exists the Zones you define.
Parents can set up to four Zones. Each KidGPS you setup uses the same Zones. You will receive a separate notification for each KidGPS as it enters and exists a Zone.
To understand the concept of Zones, think of a large, circular fence. When your KidGPS enters or leaves the area bounded by this fence, you will receive a notification. Your KidGPS checks its location every few minutes to ensure you can use KidGPS for multiple days between charges. So you should expect a few minute delay between when your child enters/leaves a Zone and when you receive a notification.
The minimum size of a Zone is 50 meters. The maximum size is 750 meters.
