No Equal RPN Calculator

 

The No Equal RPN Calculator for iPhone® and iPad® is a scientific calculator that uses Reverse Polish Notation (RPN), similar to most HP calculators produced since 1972.  RPN is more efficient for complex calculations.

 

Unlike many RPN calculators, the No Equal RPN Calculator always shows the stack.  This allows you to see both numbers before performing an operation, and it makes it easier to keep track of where you are in a complex calculation.

 

The No Equal RPN Calculator has 10 memory registers.
