Cool I guess

Awesome but it doesn’t really work I said to him I hate fish and it said it’s a lie and I like fish and my mom and dad said they were Superman and it said it was true so it didn’t really work I got upset but then it started to work when I went to my settings so you guys may have to go into your settings and see if it’s working or not because there is a switch and you have to look at it so I said I I hate cake and it said I was telling the truth so it doesn’t really work so I hope it works for you guys but I found out that you have to read it before you do anything so I rated it and it started to work I said I love cake and it said I am telling the truth so I am super happy

It’s an okay game

So I got the app thinking “this is going to be cool I can see if my parents or friends lie!” So I got the app then I tried it and I said I ate to cookies this morning which I did not and it said lie so I’m like “ this thing works! Then I tried again but I said I hate unicorns and it said truth so I’m like” okay uhh what’s going on?” Then just I’m guessing it just guesses and does not work so I mean it’s kinda a prank so you go to your friends and then it prob will say lie so don’t get this game only if you want a prank

This app is okay, but there are some things that need to be improved. 1. I hate how when you finish getting your results, you have to watch an ad that you cannot get rid of! You have to go through a whole process if you want to ask it another question! On another note, it seems like it works, but maybe it's just a coincidence.
