See the numbers in action and master this alternative calculator logic that students and professionals have appreciated for decades. Advantages include always seeing intermediate results, solving nested equations from the inside out (a logical approach), and often an increased understanding of the math compared to just copying the equation.

I know the principles of RPN, but this app looks like a great way to learn the deeper tricks.
This is my favorite calculator for iOS devices. Its a great looking RPN calculator with basic functions. The style is similar to an HP calculator. Includes enough functions for general daily, and display shows 4 registers. Only draw back was sluggish startup compared with other apps, but this seems to have been corrected in version 1.2.
I'm not a scientist nor a financialist; I just need basic math functions with semi-large keys and RPN.
Simple and easy to use, large keys and easy to read labels make this RPN calculator an excellent replacement for the built in iPhone calculator. And it is Free!
