Score one for parents, y'all.
Frustrated father Nick Herbert has created the iNgeNiOus [and diabolical] ReplyASAP app [hahaha] -- that literally makes your kid's phone unusable until they respond to you.
Not only does the app notify parents when their child has seen their message, it also takes over the screen and sounds an alarm until they answer. They straight up can't use any of their phone's other functions until they DeAL WitH iT.
ReplyASAP is free to download, and currently available for Android in the U.S. An iOS version is set to be released soon.
