What is it about?

allRPNCalc is a versatile calculator that uses the powerful Reverse Polish Notation logic system combined with an automated 4 level stack to compute answers to complex mathematical problems. The keyboard layout and display have been optimized for use on an iPhone,iPod Touch and iPad. Large keys with sound feed back give you typing confidence and the last function keyed is always displayed. Functions are logically laid out to eliminate multiple key entry for most problems.
