Customer Reviews

Almost perfect

A huge array of functions, including the ability to construct complex expressions AND edit them before solving them.
That's great if you want to work through a problem by constructing a complex expression. I often prefer to attract a problem a piece at a time, essentially working through the expression from the inside out. For that RPN notation is invaluable. RPN is not an option with this calculator, and that's its only serious weakness.

RPN sadly missing from near-omnipotent calculator

I have barely scratched the surface of this calculator and I believe its capabilities vastly surpasses my needs. Only problem, I'm irrationally attached to Reverse Polish Notation input method (from years with a 15C), which is the singly option missing here, so I suspect I won't get much use from it. This is probably only a problem for the post-abacus/pre-facebook generation.

Lifesaver in class

I'm a teacher and this calculator is a life saver in my classes. Only if it had a notification center widget and apple watch support I would name it best app in the app store!
