The Best So Far.

I have tried many calculators because the basic ones are never enough and almost never do RPN. I have PCalc for my MacBook Pro, iPad Air, and my iPhone 6 Plus and I am very happy with it so far. I especially like configuring the layouts to matvch so there is conssistancy between my Mac and all my devices. I recommend this calculator to anyone who finds that the basic calculators are not enough.
