"AppTruth, The Lie Detector" is a lie detector simulator. It is an app to check if someone is lying. Well. Really not. We have a trick to get when it is true or not. Just, change the position of the finger on the "detector button" and the app will say if "It´s true" or "It´s false". But, nobody knows it! If your friend want to press, keep pressing "Down Volume" while he is doing the question and pressing the button and the app will always show "False!". Check our Play Store section to get help.
