MathU RPN Calc

Esta calculadora RPN es definitivamente la mejor opción para el iPhone. Soy fanático de este tipo de aplicaciones y antes de llegar a esta (antiguamente la tenía en mi Palm) pase por varias: - HP 41cx - RPN calc 42s - 12c platinium - PCalc La MATHU RPN es mejor que todas las anteriores en mi experiencia por lo siguiente: - Parte en forma instantánea - El diseño es especial para iPhone, no es un emulador o copia de una real, esto quiere decir que el tamaño de los botones y la configuración esta especialmente diseñado para facilidad de uso. - La calculadora combina en una misma interfaz las clásicas y útiles operaciones financieras más las clásicas y útiles operaciones trigonométricas y de ingeniería. - Permite incorporar y trabajar con números grandes. - Realiza cálculos y operaciones muy rápido. El precio es caro, pero vale la pena, yo desperdicie muchos dólares en otras opciones que no están a la altura de esta.

This is my daily go-to calculator. It's also my absolute favorite HP emulator! It does everything I need from a calculator. Great combination of functions! Anyone who used the older vintage HPs will appreciate this calculator. Thank you Dr. Thompson for keeping this app current!

I use this calculator on a daily basis and absolutely love it. I have been a fan of HP calculators since the 80’s and glad I found this app a number of years ago.

I’ve used RPN since my first HP calculator 50 years ago. This app is a superb duplication of the original and looks just like the original keyboard. Perfect for all my scientific needs.

Been using for many years. Has surpassed my HP calculator for most purposes, though the H-P works great. RPN is the only way to go for engineering calculations. Learn it and you’ll never touch an arithmetic calculator again j

I have been using this calculator for years and found it flawless for a RPN calculator. Reverse Polish Notation (RPN) calculators take less keystrokes than an algebraic version to complete a series of calculations. This calculator faithfully executes the HP look and feel for those wanting combined scientific and business functions in one app. I cannot praise this calculator enough.

For those of us that used RPN calculators from HP all through high school and college, this is a brilliant and familiar implementation of that model.

This is the best RPN calculator I've found. Have been using it for ages. There's an issue with the last update on my iPad mini: I'm not able to access the settings anymore. The dialog will pop up, but tapping settings (or Quick Reference) won't do anything. A very personal preference: turn off display of the financial registers or replace it with first 5 regular registers. I don't use the financial functions that frequently so it's just distracting.

I have used this RPN calculator for many years and what can I say other than it works. The iPad version has some bugs with the settings and help that need to be resolved.
