WP 34s is the most powerful and complete implementation of a classic RPN scientific calculator. Now available on iOS too (see the support site for other emulators and for the real stuff).
The function set of the WP 34S is based on the most powerful programmable RPN calculators built so far and we expanded the set, incorporating programmer functions (base 2, 8 & 16), a fraction mode, probability distributions, a stopwatch...
We also included numerous additional useful functions for mathematics, statistics, physics, engineering, programming, I/O, etc., such as:
+ Euler’s Beta and Riemann’s Zeta functions, Bernoulli and Fibonacci numbers, Lambert’s W, the error function, and the Chebyshev, Hermite, Laguerre, and Legendre orthogonal polynomials (no more need to carry heavy printed tables),
+ many statistical distributions and their inverses: Poisson, Binomial, Geometric, Cauchy-Lorentz, Exponential, Logistic, Weibull, Lognormal, and Gaussian,
+ programmable sums and products, first and second derivatives, solving quadratic equations for real and complex roots,
+ testing for primality,
+ integer computing in fifteen bases from binary to hexadecimal,
+ extended date and time operations and a stopwatch3 based on a real-time clock,
+ financial operations such as mean rate of return and margin calculations,
+ 88 conversions, mainly from old Imperial to universal SI units and vice versa,
+ 50 fundamental physical constants as accurate as used today by national standards institutes such as NIST or PTB, plus a selection of important constants from mathematics, astronomy, and surveying,
+ Greek and extended Latin letters covering the languages of almost half of the world’s population (upper and lower case in two font sizes), plus mathematical symbols.

Good overall with some potential improvements
It would be great to round off this great looking and working WP 34s with a few features from similar emulated calculators (like Free42 and HP-12C):
- Printing simulation into a separate screen and saving to image and “log” files
- Shift Highlight: green and orange are somewhat similar (for some of us), so when a shift is activated, highlight the affected functions with higher intensity (brighter) color.
Other potential improvements:
- annunciators could be a little bigger
- multi-line stack, registers or program views
With the latest update, lists are unreadable
I have the HP30B and a converted WP34S. The only issues with this update is that all the pick lists are darkened and are not readable, for example, key in h and X.FCN and you won’t be able to read the choices.
Excellent
Great HP clone calculator. No issues at all and on top of that the great ol' classic look.
Very good calculator, some issues...
Excellent engineering calculator, however there is a terrible battery drain and device heating issue when the app is running. Otherwise, this would easily be a five-star app.
WP 34S
Excellent, powerful RPN calculator.
Excellent calculator
I downloaded both this one and the companion wp-31s, both are extremely well done. Just a FYI, the "show" command works differently in the two apps. I assume that the wp-31s behavior is correct and this app has a problem. Great apps other than that.
Well done
an emulated version of the WP34s calculator. This was written by folks who used HP calculators in their field, so they know what's up. It's full featured, including scientific function, calculus, matrix, complex, and computer maths functions, and it's RPN.
Seriously, give it a go! If you like RPN calculators you'd do yourself a disservice by passing this one up. I have the actual calculator and I love it. Extremely useful at university! Even better now that I can run it on my mobile!
HP34s
Wow... This is a RPN aficionado's calculator. Has most all the functions you commonly need and works great. For fun I timed how long it takes my wife, a math major, to do complex calculations with std calc vs me using the rpn. I can consistently do the number crunching in 50% less time and with more accuracy. Interestingly, she could reduce her time by ~40% even after just learning how to use an rpn.
Awesome!
Great calculator! Very powerful and an awesome addition to my calculator folder!
