Finger Lie Detector prank

"Finger Lie Detector prank" is a perfect app to make a joke of your friends. This program only pretends to be a real polygraph. It is not a real truth machine! You need to know the answer for the question to make a good prank.This entertainment application displays "TRUE" or "FALSE" on phone screen when your friend puts his finger on scanning pad, answers the question and moves his finger away. You are able to choose if the answer was truth or your friend lied. Just follow these instructions to make a perfect gag:1. Cheat your friend that your mobile can detect lie based on finger pulse, pressure and sweat production.2. Tell your friend to put finger (thumb will be the best!) in the center of green scanning pad (on fingerprint image). Red scanner line will start moving under your friend's finger.3. Ask the question you already know the answer to.4. When your friend tells:TRUTH
- tell your friend (or force him) to move his finger away when the red scanning light is in the TOP HALF of green scanning area.LIES
- tell your friend (or force him) to move his finger away when red scanning light is in the BOTTOM HALF of green scanning area.

This has a simple pattern, so simple I a 12 yr old could figure it out, when the scanning line is on top half, it's true, otherwise it's false.

The app itself isn't that confusing, but every time I open the app an add pops up and I can't click out of it! If I try to click out of it, it just opens the add! Please make the adds pop up so you can actually CLOSE OUT OF THEM!!!

So sneaky to trick someone lol this will work with any part of the skin not just your finger you could put your elbow on it. If they wanted our finger print they could get that when I text
