If you’re a parent of a teenager, chances are your kid has ignored many of your phone calls and texts. Well, thanks to a Houston mother who was frustrated with the same problem, those days are finally over. Sharon Standifird, who has served in the Gulf War and climbed Mount Kilimanjaro, was so furious when her 17-year-old son wouldn’t return her phone calls that she invented the Ignore No More app which locks her son’s phone if he doesn’t call or text her back. When her son returns her call, the phone is unlocked. Now millions of other parents are installing the app on their own kids’ phones and it’s become a huge smash hit. The app can be yours for $1.99 and is currently available only for Android users, but an iOS version is in the works. You can learn more by visiting IgnoreNoMoreApp.com.
