Lie detector: test app for iPhone and iPad

Lie detector: test is a real truth detector app, also known as a polygraph test.
Indeed, it allows you to tell if someone is lying or telling the truth.

To use the lie scanner:
Cover the back camera with your finger and say something.
The app will scan your fingerprint and understand if what you say is a lie or a truth.
The lie detector will measure your pulse and give you a result based on the variation of your pulse. It is a true mind reader.

This lie detector works like a true polygraph test, indeed like a real test it can detect your heartbeat in your finger.
It measures and records your pulse while a person is asked and answers a series of questions.

For a good laugh, prank your friends, use the truth detector on your family members or friends.
