A new app called ‘Ignore No More’ allows parents to make sure their kids call them back. However, parents need to install the app not only in their smartphones but also in their kids' phones as well.

In case a kid ignores his parent's call, the parent can remotely lock the device with a password only known to him/her. The kid must then call his/her parent to get the password.

"We need to develop an app that just shuts down the kids' phone," its developer Sharon Standifird said.

The kids cannot uninstall the app on their own as the parent's username/email and password are required to unregister or uninstall the app from their phone.

In case the kid tries to disable the app, it automatically locks itself and sends an email to the parent.
