## What is Liar?

The first real lie detector for mobile is here, the app will try to track your stress rate from the camera, and an AI will detect from it if you're lying or not by looking at your heart rate.

Crazy right? Stress is what CIA used to look at when creating a lie detector, so we wanted to give you the same tools to discover the truth, lie, or not? Find out.

Note that the lie detector need electricity to keep working! This is why we've implemented in app purchases, for every Lie detected, electricity will be used.
