An app that adds a widget to easily turn off and on screen lock.

[AC Question]

So I was wondering if you guys know an app that'll add a widget which will be able to turn on my PIN screen lock and then turn it off to swipe lock or no lock with another click. When I'm at home I don't need to lock my phone and constantly pressing the PIN gets a little annoying. Then when I'm out in public, I can just switch the widget on, and it'll PIN screen lock my phone.
