This Relay tracker is perhaps the best thing out there that ensures your child’s safety whenever you’re not with them as it keeps you informed on their whereabouts at all times. It works like a 4G phone and a walkie talkie and uses GPS tracking to locate your child in the Relay app. Sets Geofences such as “home” and “school” and receive automatic notifications when they enter/leave any of these set locations. Your kids can send SOS emergency alerts to everyone who’s been added on the account, which will continuously go off until the account owner has resolved the alert. If you have a mischief dog that tends to take off on its own, this might be a good reliable tool as well.
