Do you want to prank your friends into thinking that your android phone can detect the mood they are in? 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 'good mood' answer and tap it on the right side to get the 'bad mood' answer. At least to some degree. You can decide if the victim in in the good mood or bad by yourself and then tap on the appropriate side of the screen to the desired effect.

Please note that app is just a prank, funny simulation that's meant to make you and your friends laugh.
