HOUSTON, TX (CNN/KTRK) — For parents of teenagers, not knowing where your child is can be frustrating, even frightening. And giving them a cell phone doesn't always mean they'll answer.
That's why a Texas mom took control and invented an app that her kids -- and yours -- can't ignore.
Sharon Standifird was livid the day she called and texted her teenage children and they didn't respond. Once she knew they were safe, but ignoring her calls, she got an idea.
"We need to develop an app that just shuts their phone completely down and they can't even use it.," said Standifird. "And I started- literally just started researching how to develop an app."
Her husband William says he wasn't surprised. She's served in the Gulf War in Iraq as part of the military police and even climbed Mount Kilimanjaro.
So becoming an app developer was just one more challenge for this mom on a mission. After months of design and working with developers, "Ignore No More" was born.
"As a parent, all I have to do is touch the app, tap his name. To lock Bradley's device, enter at least a 4-digit unlock code, and now I'm going to press 'lock Bradley's phone.' And if you watch Bradley's phone, it's going to go blank. Bradley needs to call me because I'm the person that has the unlock password."
With one tap, a list of only parent-selected contacts comes up. The child can call, get the password and unlock the phone.
"It takes away texting, it takes away the gaming, it takes away calling their friends. The child will always be able to call 911," said the inventive mother.
So, how does her son feel about the idea?
"Well, I thought it was a good idea, but for other people, not me," Bradley stated.
"I do have to say that he responds to my texts and my calls a whole lot quicker than he used to," said Sharon.
The Ignore No More app is only available for Android phones on Google Play. It costs $1.99 cents.
