Quick and Fun!

Ok, I'm just going to tell you all right now that you shouldn't judge it because it isn't accurate! The point of it is to have fun! Now, this has absolutely no lag, no glitching, and it's fun for young ones! I remember playing lie detector games at seven years old. I couldn't get enough of them! This one isn't complicated like all the other lie detector games. It's simple, you place your pointer finger or thumb on the fingerprint, and it almost instantly tells you if it's a lie, or the truth! This is probably the best you're going to get to a lie detector app.

Entertaining app!

My eight year old has plenty of fun with this app. He enjoys playing lie detector with friends and especially family. The easy to read truth detector is great.
