If you already know, experts use a polygraph tools that needs to be paired with our nerves all over the brain to assess truth and lie by analyzing signals on the monitor display. If that sounds legit, then lets barge forward to jump into the virtual fake reality.

The truth is, there is no such app, nor any machine that has an ability to detect our deep desires or innermost emotions dumping Intricate puzzles. However, there are a few lie detecter apps that you can use to play a prank on your friends before they know it’s fake.

How do such apps work?

Such apps come with a unique strategy, and graphics to help you test bait lie detection on your friends in order to have fun.
