Think the government listening in on your phone calls is worrying? How about strangers instead? Software developer Lauren McCarthy made an app called Crowdpilot. It lets everybody spy on you.

The basic idea behind the app is to let people listen in on your phone calls so they can offer you advice on what to say next. Total strangers that get paid a dollar to listen through Amazon's Mechanical Turk program, or any combination of those options.

You can specify what kind of conversation it is—date, argument, meeting, etc.—and the listeners can text you words of encouragement while you're on the phone. Download it here.
