Without a doubt, this is the ONLY rpn calculator set to use, it does EVERYTHING. My (4 or 5) HP calculators have been in a drawer since discovering your great contributions to the technocratic world and everyone wishing to ease the mundane tasks of numeric calculation. I have been using and LOVING this superb application of calculators for so long that I feel as though the developer and I are friends on a first name standing. What a great application set. Well done to Laurent Rodier.

I've been using an HP 12c and 15e forever and this is the best app to replicate the Hewlett-Packard experience I've found. First on Windows Phone, now on Android. I wouldn't use any other.

Of your advanced products, ie my Rpn2, my rpn has the best keyboard layout including the copy paste function. Even though it has only a single visible line of the stack its still superior. Keyboard on rpn2 just plain sucks

Trying to switch modes to statistics. I think the L key does this? Sometimes it works. Most of the time it doesn't. Tried to use the user's guide but it doesn't work either. I'm a software engineer and I can't get it to work.

Excellent app. Combines most HP 10 series calculators.

About this app

My RPN calculator 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.

The application is designed for small screens (less than 5.8" smartphones or tablets with less than 2000 pixels on their largest side). For larger screens you should look for the update-to-date and maintained My RPN Calc Ex version of the application that is intended for all screen.

These software version has borrowed the RPN (Reverse Polish Notation) and the look&feel of those calculators. 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.


Its unique magenta L key allows switching from one layout to another, thus saving space on small displays like smartphones without compromising usability.


Support for gestures allows switching from one keyboard to another by swiping left or right, and a light swipe up or down on a key executes the associated f or g function, without any need to actually press the f or g key.  
See the web pages of the application at http://calc.lsrodier.net for complete keys description and samples.

My RPN calculator is compatible with all devices running Android 2.1 and up and supports both horizontal and vertical orientations. It does however requires a device with a minimum screen resolution of 320x480 (or 480x320 according to orientation). Note that tablet screens are properly managed.
