Sharon Standifird has climbed Mount Kilimanjaro. She served in the Gulf War as military police. But these things seemed like a piece of cake compared with the challenge of getting her teenage kids to answer her calls and texts.

If you have a child with a cell phone, chances are, you know how frustrating -- and frightening -- this can be.

Standifird certainly does, and one day, when she'd had enough, she got an idea: what if a parent could simply shut their kid's phone down -- from anywhere in the world -- making it completely unusable until the child called back?

But an app like that didn't exist, and Standifird didn't know the first thing about developing one. So, naturally, she taught herself how.

From the ground up, Standifird created Ignore No More, an app that, with one click, remotely shuts down all functions of the child's phone -- calling, texting, gaming, everything.

The only functions left working are the ability to call 911 and access to a predetermined call list, with which the child can call mom or dad back for a password to unlock the phone -- after the obligatory I'm-so-glad-you're-alive-so-I-can-kill-you speech, of course.
