Psychology: Truth Lie Detector is an educational app that aims to help users understand the reasons behind lies and how to recognize them through body language. Developed by Iurii Kriuchkov, this free app is available for iPhone users.

The app provides insights into the psychology of lying and teaches users about non-verbal actions that can indicate deception. It explores topics such as why people lie and the different signs of lying. By understanding body language cues such as gaze direction, touching of lips, types of handshakes, position of legs, and even lying over the phone, users can gain a better understanding of the people around them.

Psychology: Truth Lie Detector is not only useful for individuals who want to better understand the psychology of lying, but also for professionals in fields such as law enforcement, security services, and psychology. It can be a valuable tool for head managers, scholars, students, and anyone who wants to enhance their knowledge of non-verbal communication and improve their ability to understand people.

While there are no foolproof methods to detect deception, this app provides valuable insights and principles of body language that can help users in various aspects of their lives, from personal relationships to public speaking and negotiations.
