This desperate dad will be ignored no longer.

Nick Herbert was sick of his 13-year-old son, Ben, disregarding his text messages. So the project manager from West Wickham, England, developed an app that would effectively hijack the teen’s phone — by sounding an alarm and covering his screen — until he wrote back.

ReplyASAP is either a savior for frustrated moms and dads or a silly tool for helicopter parents, depending on whom you ask. The app, which is currently available for Androids but not iPhones, has been downloaded over 75,000 times since it launched in August 2017, according to its Google Play Store page.

Herbert’s tech-savvy parenting hack is garnering renewed attention ever since he told the Mirror that an iOS version is in the works.

However, the new wave of press has some critics wondering if the app is being misused.

“I can ASSURE you abusive and controlling significant others will utilize this,” one concerned reviewer wrote on the app’s page. (Herbert responded that this is unlikely, given that both parties have to agree to install ReplyASAP, and users can in fact be blocked.)

Herbert is not the first slighted parent looking for a way to grab their kid’s attention.

In 2014, Sharon Standifird launched a similar app, called Ignore No More, which could lock a child’s phone until they called their mom or dad for a password. At the time, the product sparked a debate about whether today’s teens should be afforded a level of independence from their parents. (BTW: Ignore No More is no longer available.)

Meanwhile, Herbert says his invention — which can be invoked by the teen user as well as the parent — is meant only for “important things.”

“During the development process, I spoke to Ben,” Herbert told the Mirror. “He likes the idea because he will know if he gets one of these messages, then he will always hear it and will know it’s important.”
