My RPN Calc

My RPN Calc is a versatile RPN calculator with a clean and minimalist interface for iOS.
It is a scientific and financial calculator inspired by the Hewlett-Packard HP-10C series pocket calculators of the 80s, most notably the HP 12C and HP 15C models.
It features classical 4 operations, logarithms, trigonometry, statistics, financial, and macros for easy programming.
It also features complete support for complex numbers along with 2nd, 3rd, and 4th degree equations solving, numerical root finder and integration.

Though it is not a complete emulation of the HP-1xC, it can easily substitute them for all classical, scientific, statistical, and financial operations.

Exhaustive user manual with many practical examples is available on the home site of the application.
