FAQ

What does the Lie Detector Test Prank app do?

This app simulates a lie detector using fingerprint or eye scanning to determine if someone is telling the truth or lying. It's designed for entertainment and pranking friends and family.

How does the lie detector simulation work?

You can place a finger on the fingerprint scanner or use the eye scanner feature. The app simulates an analysis and then displays a message indicating whether the person is telling the truth or lying.

Is this app free to use?

The app is free to download and use, but it does contain advertisements. There may also be in-app purchases available for additional features or to remove ads.

What are the additional features in this app?

Beyond the lie detector simulation, the app includes a 'Test Dual' feature for two-player checks, a 'Beauty Score' to rate faces, and a 'Love Detector' to predict love scores, all for entertainment purposes.

Can I control the lie detector results?

Yes, the app provides a 'Tips for you' section where you can press '+' for a truth result or '-' for a lie result, allowing you to control the outcome of the prank.
