App helps parents keep track of kids in crowds

Posted: Updated:

A North Texas man who got separated from his child at an amusement park has created an app to help keep track of kids in big places.

The Buddy Tag features a wristband that the child wears and is connected to an app on someone's smartphone.

"Whenever the kids wander too far away the app will sound the alarm vibrate the phone and pop up a message to let you know hey the kids too far away," said app inventor Willie Wu.

Wu invented the Buddy Tag after his daughter got separated from him one year ago at Six Flags.

"She was traumatized, she was scared for hours afterwards," said Wu. "It was dark, it was closing hour at Six Flags. It was dark, hard to find people, everyone going out the door to exit. It took us forever to find her."

Wu said he's also designed a way for the app to be used with infants.

In one example, a parent who walks away from a car with a child strapped in a car seat would trigger the warning alarm.
