Description

MathU RPN is an advanced scientific and financial calculator designed in the spirit of classic HP calculators. MathU RPN is based on the Reverse Polish Notation (RPN) entry system and combines more than 96 functions to create a calculator that meets the needs of professionals who use a calculator every day.

Dr. Clay M. Thompson of Creative Creek has harnessed the computational power of the iPhone to produce an accurate and high performance calculator.

MathU RPN 3.2 has been reformatted to work on the iPhone and iPad. On the iPad, MathU RPN maintains its orientation as the iPad is turned.

MathU RPN 3.2 a great programmer's calculator. The A-F keys are available right up front for easy entry in HEX mode and there are many functions for working with integers.

MathU RPN 3.2 is also a better financial calculator. There are new functions for computing mortgage amortization and cash flow computations like IRR and NPV, as well as functions for working with dates. Many of the existing financial functions have been extended to handle odd periods (conforming to the same conventions as the HP-12C). In addition, on tall devices (like the iPhone 5 or higher), the financial registers are displayed on the keypad.

The scientific side of MathU RPN has also been improved by adding functions for linear regression as well as computing the percent of total.

MathU 3.2 supports iOS 9.3 or higher.

Really great RPN calculator

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.

Love this calculator!

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!

Great RPN app

This is a really great RPN calculator app that has been available for ios for many years.

I would love if this app offered a skin that showed basic functions for a much easier to use view.
