Real Lie Detector

Free
Real Lie Detector is able to detect estimated lie probability from hearth rate and voice stress analysis. It works similar to the polygraph, but uses device's camera to detect heart rate and microphone to detect voice stress. In order to detect heart rate, the examinee has to put his fingertip on the camera lens. In order to detect voice stress, the test needs to be done in a quiet and calm environment and the examinee has to answer all of the questions with his voice, saying "no". At first the examinee has to answer a few of the predefined test questions. After that he/she will have to answer on the actual relevant question, that is selected before the test. Finally, the estimated lie probability will be displayed. Please note that the lie detection results can be misleading, especially when the examinee is not under real stress. This is the free version with ads. Feel free to email me if you find a bug of have any trouble with the use of the lie detector.
