Do you want to know if someone is lying or telling the truth? Well impress or fool your friends/family by using this lie detector simulator app. The free app needs to be calibrated before using. Calibration: Press calibrate button and follow the instructions, given in audio and text format. Ask the interviewee TWO questions where the answer has to be Yes. Then ask TWO questions where the answer has to be NO. Usage: The trick to using this Lie Detector is to preset the result of the scan before they place their finger on the fake fingerprint scanner. You hold the phone so that the other user is sat in front of you. If you are going to ask a question where you want the answer to be NO then press the reset button towards the right side edge. If you want a YES result then press the button towards the left. To avoid being caught or so no one figures it out dont touch the button at the same place. Press the RESET button to start. Ask them a question clearly then tell them to place their finger on the scanner. After a few seconds the app will tell you if they told the truth or lied, as you have wanted. Important note: This is a prank / Joke app and not a real polygraph or lie detector!
