Is there an anti-social app for iPhone users?

My parents where telling me about some app that they heard on the Katie Curric show talking about being able to "blackout" your phone for a day or 2, but there's also an app that limits you to no social networking sites. I can't seem to find it and was hoping that maybe someone else knew of it?

Search the App Store And See if you Can Find It Chances are Its Probably in There Try Putting in the Description of it and See if Any Apps Come up By Using That
