MathU RPN 3.0 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 3.0 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 3.0 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 3.0.3 supports iOS 8.0 or higher.

Love this calculator!
Bearcreekmom
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.
Great calculator
CummingJim
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
Really great RPN calculator
biz217
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.
Long a Favorite
Bozocity
I enjoyed MathU for years on Palm OS. It was the first app I sought to buy on iPhone, but at first I passed when it was available only by annual subscription. I snapped it up immediately upon seeing the $9.99 introductory offer. MathU is better than immitation HPs, because it is always optimized for its platform. I am glad to see the shift in pricing and am pleased to continue supporting this developer. Thank you for bringing MathU to iPhone!
Best PRN Calculator

I only bought the G3 because this program was coming. The Palm version is great. I hope this one will be upgraded to match the Palm version in short order.
This is the RPN Calculator to Get

An old favorite, nay necessity, from my Palm days, I'm very happy to have this essential application for my iPod Touch. It works just like an old school HP Calculator, circa the HP-11 and 12 series, with the added bonus of an extended stack and scientific as well as financial functions. The original for the Palm was programable and there were several program suites that you can add on -- I hope these feature are forthcoming. However, given the excellent execution of this program, it's ease of use, and Creative Creek's very fine customer service, I do not hesitate giving this app 5 stars. Well done!
Almost Perfect
RPNlover
OK, I've had (have) MathU Pro on my Palm Tungsten & my mobile PC phone. So I had to get it for my iPod Touch. For most calculations it works as it does on the other 2 platforms (which is perfect), but there are a couple of things that could improve it: 1) Add programability. 2) Make it so that ABCDEF entry while in Hex mode is not a 'g' function. I'm thinking that if I'm doing hexadecimal calculations that I am not doing financial work; which are the unshifted functions of the same "keys.". 3) Be able to review registers. I've used an RPN calculator since my first HP11 24 years ago (Actually I still have it and it still works), and have trouble with arithmetic entry anymore.
Thousands Commas
dansm15
Love this app. Now I don't have to carry my 12c around as well. Maybe I just can't figure this out, but does anyone know how to set preferences to display commas to show thousands separated? Having this feature, would sure be helpful to me.
As good as it gets

As a long-time user of the Palm version of MathU I was very happy to see it become available for my phone. I no longer need to carry my Palm (R.I.P.). After a very short "break-in" period, and learning that [G][G] gave me access to preferences such as the number of digits, I am using this version as readily as the Palm version. The iPhone version is elegant, easy to use and versatile. This app could serve as a standard for iPhone programs. Bravo!
