About this app

LieScan is a lie detection simulator (and not a real lie detector). It doesn’t detect lies but allows you to record your voice and control if a truth or a lie must be displayed.

You can control the result manually depending on how you press a button, or randomly by setting a probability.

This is a great way to prank your friends or family! Let them take a lie detector test and control whether they tell the truth or not. They might think it’s a true lie detector and confess some truths to you!

This app contains ads and an in-app purchase to remove them.

I actually love this app. I love how there are options for either random or manually decide app's response by tapping each half side of the mic button for TRUE (right side) or LIE (left side), which is pretty smart. None of my friends realize or find out this trick. 😂😂
