**Don't be fooled by cheap knock-offs, This is the original iPhone Lie Detector.**

***As Seen On Nickelodeon's Show Degrassi***

Lie Detector can analyze a person's voice and determine whether or not they are lying. Lie Detector uses a sophisticated and accurate algorithm that looks at pitch, frequency, and peaks in the voice and compares it to calibration questions.

Lie Detector even gives you a frequency comparison of the person's truthful answers to the questionable one so you can decide how truthful they are being.

-Find out if someone is lying about whatever "yes or no" question you decide to enter based on their voice.

When a person speaks they produce inaudible fluctuations called microtremors. When a person becomes stressed, physical changes such as increased blood flow cause the audio range of the microtremors to change. Lie Detector analyzes this change to determine how stressed, and therefore how truthful, a person is being.

**iPod Touch REQUIRES an external microphone**

Note:Lie Detector analyzes stress in the voice, just because someone has stress in their voice does not necessarily mean that they are lying, only that probability that they are lying is higher. Also if someone is nervous and taking the test, there is a higher chance it will output their answer as a lie. So make sure whoever takes the test is relatively calm.

Best app ever

This is the best app i ever seen forces people to be honest and truthful , it helped my marriage I know more about my wife and my wife knows more about me . if there was only a way you could record conversations to find out if that person was being truthful would make it the most talked about app in the world.


This app will crash on you an does NOT work. I know it's only 99 cents but you'll sill feel like a dummy for buying it. It may work for some but I can't tell u if this app is good or bad cause it flat out doesn't work! As soon as you start a session it crashes and goes back to your home screen. Many peoples' experiences may be different, but either way it should work for everyone.


Hi. This App has a huge problem. I recommend you to NOT buy this app, because it frequently crashes to the home screen right before you can even ask the question you want the person to answer. Unless they can fix the bugs, do not buy this worthless thing.
