It’s pretty good

Before I rated it every time I said something it was correct, after I rated it one of them was false, which I said I didn’t do this, and it said true. But I actually did do this thing, I did it 4 times, 1 was correct. After that I asked a different question, and another. Both of those were correct. I have no idea if it really works, but it’s sort of creepy that only one question that I asked was false. I asked it more than once, but it was only that question..

Not correct read and you will learn its garbage

Ok so I tried this game I read the reviews and it was a 80 percent chance it would work the in app purchase is only 1.99 so great it got it right the first 2 times but then I said I had seven cats which was a lie cause I only have 2 and it was like... YOU ARE TELLING THE TRUTH! And I was like no I’m lying so this game is kinda lying so TWO STAR like it’s good for price but accuracy is like 2% and it really was a waste but when I read the reviews I was like oh ok maybe good... NO COMPLETE WASTE also took 2 hours to download so yeah little bit garbage no the people who made this game might be mad but like use science like what did you learn in science class bro like did you fall asleep in class like ding ding ding wake up and learn something like your game is inaccurate it’s very much garbage like LEARN people you may be mad at me but I DONT CARE 😡 stupid game don’t download I was so excited for nothing but my pop it fidget toy just came in the mail so I can leave and delete this stupid game😡😡😡😡😡😡😡😡😡😡😠😠😠😠😠😠😠😠😠😠🙄

This App is Genious

First of all this app does not work how you may think. This app is explicitly a perfect prank app. It sadly doesn’t actually tell you if your lying or not but it does something that’s just as good if used correctly. How you use this app is when it gives the option to “start scanning process” if you press on the right side of the screen it will always say false, and vice versa for left, it will say true. This app is perfect for pranking some friends and just messing around
