Lie Detector Prank

Do you want to test whether your friends tell a lie? Do you want a accurate Lie Detector?
Congrats! This App is not... 'Lie Detector' is a prank app for fun.
Even though it is a prank, we confirm it looks like a serious Lie Detector.
How to play:
1. Choose one person to take this lie detector test.
2. Press the button and scan the fingerprint. At the same time, let him/her say what he/her want to say.
3. The APP will detect whether he/her tell a lie or truth.
The most important trick
You can tell this APP to respond with truth or lie.
When the tester press the button, you can judge his/her words by yourself and click Volume UP (for truth) or Volume Down (for Lie).
Enjoy it with your friends and family!
