Lie Detector & Lie Test Scanner: Truth or Prank?

Lie detector apps have gained popularity as fun tools to test whether someone is telling the truth or lying. While real polygraph tests analyze physiological responses like heart rate and sweat levels, lie detector apps use simulated fingerprint or eye scans to create an entertaining experience.

How Lie Detector Apps Work

Most lie detector apps function as prank tools, displaying random results based on user input. Some apps allow users to preset outcomes by discreetly pressing volume buttons or adjusting settings.

Common Features

Fingerprint Scanner – Users place their finger on the screen, and the app generates a “truth” or “lie” result.
Eye Scanner – The app analyzes eye movement and pupil dilation (simulated).
Voice Analysis – Some apps claim to detect stress in speech patterns.
Customizable Results – Users can control whether the app shows “truth” or “lie.”
