Android RPN app?
Greetings,
I am curious which RPN calculator app you use on your Android device. What do you like about it? What don't you like about it? I'm leaning toward one that will have the look and feel of a 15C or 16C, or maybe 48G. I'm willing to pay (~$10) for a decent app that doesn't track or spy on me. A search of "Android RPN" on this site only returned a thread that I didn't see any apps. Thank you. P.S. I am not sure if I should be using the "poll" option for these questions. 10B, 10BII, 10C, 11C, 12C, 14B, 15C, 16C, 17B, 18C, 19BII, 20b, 22, 25, 29C, 32SII, 35, 38G, 39G, 39gs, 41CV, 48G, 97 |

RE: Android RPN app?
There are several available.
Free42 is a rewrite that emulates an HP42S. The author, Thomas Okken is currently maintaining an extending it. Touch RPN can emulate the Voyager series. HP has published 12c and 15c emulators. Also, Prime lite, and Prime Pro versions. Some have reported that these are missing from Google play store. |

Personally, I use Free42, Emu42 and Emu48. Emu42 and Emu48 are emulators, but you need to supply the ROM images yourself for Emu42. (There are ways to get those though, even if you don't own the emulated calculators.)

I like the go41c, a very good and free implementation of the HP-41C. But the paid version go41cx is a huge disappointment (can't load/save programs on latest android).

RE: Android RPN app?
Wow! That was quick, even though I asked about Android apps, I went to
https://thomasokken.com/free42/ and downloaded the Linux version for the computer I'm currently on. I'll probably load Free42 on my new Android tablet as well. Thanks! 10B, 10BII, 10C, 11C, 12C, 14B, 15C, 16C, 17B, 18C, 19BII, 20b, 22, 25, 29C, 32SII, 35, 38G, 39G, 39gs, 41CV, 48G, 97 |

RE: Android RPN app?
For none programmable RPN calculator app on Android devices I used CalcTastic
To find this app in Google Play Store search: Scientific Calculator Plus Here is the website to CalcTastic: https://calctastic.com/ This calculator can be use either as Algebraic (Prefix or Postfix) or RPN Calculator Modes with three type of calculator. 1. Basic 2. Scientific 3. Programmer I used the Basic with RPN mode most of the time for quick on the go calculations since it got all the must have everyday use funtions such as [%] [X^2] [1/x] The stacks that can be set to specific user setting with feature included SWAP which is the [X<>Y] and DROP act like [R↓] --------------------------------------------------------- For a programmable RPN calculator . I used many app and one that is very popular is the Free42 I found that the Free42 is very powerful but need lot of learning to get use to it. Instead I like the Touch 11i this calculator is the HP-11C simulator app that work just like the 11C and the main advantage is that "programs can be load and save." Other than that I also keep the original HP Calculator App HP-15C HP-12C HP-12CP HP Prime Pro ------------------------------------------------ Gamo |

A little rough around the edges, but newRPL also has an android app. The Linux desktop version we don't release it in binary form but you can compile from sources (like a good Linux citizen) simply following the wiki if you are up to it.

RE: Android RPN app?
I most use Acron Calculator. This is a rework of the Acron RPN Calculator with CAS capabilities, though is still an RPN calculator. You build your algebraic statements using RPN commands and has pretty well thought out presentation of results. Checking my kids pre-algebra math was much easier with this than any other calculator.
Free42 is useful when I want a more pure RPN experience. -jgs |

RE: Android RPN app?
Actually, I have got emulations of RPN's HP-41C, HP-11C, HP-12C, HP-15C and HP-16C running on my Android handy through the PockEmul application.
In the same time, I am not limited to RPN only, I get in the same application efficient emulations of a lot of other brands and models, with printers, plotters, extensions, ... Non exhaustive list of brands and models: CASIO fx8000g, PB-1000, Fx-890p, Z-1,... Tandy/Radio Shack PC-2 PC-3 SHARP PC-1245, PC-1250, ... PC-1350, PC-1360,... PC-1401, PC-1403,... PC-1500, PC-1600,... PC-E500, PC-E550, ..., PC-G850V // a lot in (blue) Japanese or (brawn) international version // Texas Instruments TI-57, TI-74 BASICAL, TI-95 PROCALC Seiko, , Nec, General LBC, SANCO, ... All session can be saved locally or on a dedicated Cloud page which make any sharing of displays, printings or program's codes really as easy as sending a tweet or transferring files on My Drive ! This allow me to use actually my handy as an pocket emulator on the field and make tests and developments or to write documents about my programs or tutorials on my PC where, with no extra charge, I can run all these emulated calculators full screen and easily exchange data, code and documents with my real pockets and calculators connected by data or audio cables to PC's connection toolkit applications. Really a good application and a must to have for any serious old fashion computourist. [attachment=9058] |

RE: Android RPN app?
Hello!
I have several RPN calculators on my Android phone which I all use every now and then ("Touch11ifree", "RPNplus", "HP21", "WRPN 16c", "Free42", "a41CV", and some more). The one of the RPN apps that gets used most often however is "HP67". But I must confess that the calculator app I use more than all the others together on the phone is "ti5x" which emulates the Ti58 and 59. Regards Max |

Hello!

(((2x(2x(2x(2xSIN(2x(2+2^(2+.2))-(2+2))))))/2)/2) First, you can leave the outermost parentheses away. It would have worked with these as well, but 8 levels of paranetheses are enough (because the calculator knows about operator precedence, the parentheses around the 4 multiplications at the beginning should also be obsolete, unless the equation for some reason requires them): ((2x(2x(2x(2xSIN(2x(2+2^(2+.2))-(2+2))))))/2)/2 All you have to do now is move the sine (which is a postfix (?) key) behind it's argument: ((2x(2x(2x(2x(2x(2+2^(2+.2))-(2+2))SIN))))/2)/2 and you can type it in as it is written here... All this would of course be much easier if one would start from the equation. Regards Max |

RE: Android RPN app?
I really like the "RealCalc Scientific Calculator" app. Clean and good looking, perfect for quick calculations.
Purchased the "Plus" version, this is one of the first apps I install on any new Android phone. Wish there was a similar "real" calculator on the market... ? |
