This app is stupid I got it and did it on myself. I laid it flat on my computer and the line thingie didn't move at all. Then I shook my iPod and it was so high that the line went off of the screen. The reason i gave it 2 stars is because when you lie you shake. But I am shaking while I'm writing this loooooooong review. Oh and btw I didn't put my thumbs on it at all. Waste of time but kinda fun to shake and make the line go really high. And again btw this app is a lie!!!!!!!!!!!!!!!!!!! I laid it flat and pressed show result and it said 66% truthful and then I shook it a lot and it said 1% truthful!!!!! At the bottom real tiny it says this app is based on motion analysis!!!!! It has nothing to do with your thumbs!!!!!! 

This app looked kinda fun to try so I downloaded it but when I opened the app it didn't load and so I couldn't even play it. I was reading some reviews also and people should realize that it is just an app and it is supposed to be fun so it won't always be 100% accurate so don't expect that if you get the app. Other than that the app looked really fun I wish I could play it. 😌

It really works

Okay I know your thinking it doesn't work that that's a bunch of # but it's not the way that it works is that your thumb has it's own pulse and when you put it on the phone when the app turned on it feels your pulse because if your pulse is really really fast that means your uneasy and your lying but if your pulse is normal then your not lying that's what this app is bases on
