First, the good. By forcing a noisy keypad on everyone, it led me to find the scientific calculator by CalcTastic. Basic mode of CalcTastic blows Samsung's calc app out of the water. The bad. Samsung made the keys make noise every time you press one, and you can't turn it off without changing settings for other apps as well. Any review of more than two stars is for an old version of the app or worth ignoring. Remove the nose and it's a solid 3 star app, but can't match CalcTastic
