This is a promo app based on i.Decide
but has nothing to with "decision maker", instead, you can use it to pull a prank on your friends. isn't it funny?

All you need is to persuade your friend this is another kind of app, such as a decision maker, a fortune teller, or a wheel of fate. just ask your friend to start it off. Unsuspectingly, the pointer will fly away! look at his face now!I bet it will make you laugh.;)

All you have to do is shake the device to reset it.
