Fingerprint Lie Detector is a free Android app developed by Fortune Laboratory. This app falls under the Lifestyle category and is a fun simulation of lie detection. The program features cool graphics, including a finger scanner, display panel, indicator graphs, and scan graphic, along with realistic fingerprint scan animation. The app also includes audio effects, electric signal diagrams, and an electric measure device.

To use the app, users can ask their friends to tap and hold their finger on the fake lie detector scanner. After the process ends, the fingerprint lie detector will provide a result of TRUE or NOT TRUE. While this app does not actually test for lies based on fingerprints, it can provide a fun and entertaining experience for users.
