Do you want to prank your friends into thinking that your android phone can detect their iq? It's not hard. Just install this application and you can start making jokes out of them. Use the detector to your advantage - you can have some influence on the output. Just tap in on the left side of the screen to get the 'smart guy' answer and tap it on the right side to get the 'idio' answer. At least to some degree.
Of course it's best to be used on some parties where there is plenty of people around. Just tap the 'idiot' part and give it to some intelligent person. Then have a lot of fun.
Please note that app is just a prank, funny simulation that's meant to make you and your friends laugh.
