Lie Detector Pro is a fun app that allegedly can detect whether you are generally a liar or generally truthful, but mostly it's just fun to play with. To start the test, place the iPhone in your hand, read the instructions, and hit Next. From there you will be asked a series of questions onscreen, and you will need to speak your answers out loud.
The app supposedly measures your stress level, the tonality of your voice, and whether your hands are shaking to detect if you are dishonest in your replies. The questions are mostly simple ("What is your first name?") with a few more-personal questions ("Are you in love?"), and you end the test by speaking off the cuff for 10 seconds so the app can analyze your voice.
Does Lie Detector Pro work? Probably not, but in our testing, walking around the office to see who is the biggest liar was certainly a lot of fun for all involved. The app does not allow you to ask specific questions, which is probably a good thing because we wouldn't want people to end relationships with best friends over a lie detector test on the iPhone. Still, Lie Detector Pro is a great party trick and it's even fun just to see what score you get by trying to lie convincingly on every question. Anyone who wants a good app for hanging out with your friends to see who is the most honest (allegedly) will like this simple app.
