RPN Scientific Calculator for Android?

I like my "Droid48" which is an emulation of the hp48g. I have also downloaded an hp41 emulator which seems fine as well. I use a 7" tablet, and I don't know how well it would work on a little phone-sized android (as far as the smaller buttons.

I like having a real, live calculator as well. I found an hp48sx on line at a very reasonable price. They seem to go for less than the "gx"s and be extremely powerful as far as calculators go.

I've used an HP 42 since about 1995. Keys have stared to not always work. Found Free42 for Android. I like it better than the original calculator.

Whoops! :-$

I actually have 3 aps on my android.

RpnCalc is not programmable but i find myself using it most of the time.

Droid 48

Free42

Free42 works great but the functions are 2 button clicks instead of 1
Like the 32sII

PS: I also liked the 32SII but had to change to a 33 when it died
( They shouldn't have moved the Enter Button )

You can also browse the play store.

If you find another one that works good please post it.

Good Luck !! 🙂

go to fixmycalc.com or something like that, i bought a 15c off randy, and he fixes them for very reasonable prices

I downloaded Olivier De Smeet's go41cv and Andsens HP41 Simulator (a41CV) since directed to them by the other thread. They both work well, but between the two, I like De Smeet's better because it looks bit more like the 41 face, is easier to read, and seems to have better responsiveness to the touch screen. I don't know the programming behind it that makes a difference in the touch screen response, but it's noticeable.

First, sorry for your loss.

Second, I have a 'new-ish' hp33s at my desk for quick calcs- the kind w/ the chevron keys.

Third, I have a HP35s in my laptop bag that I take to the field. Yet, 95% of my field calcs are done with rpncalc on my phone. The 35 s is just in case it gets real down and dirty, even then it ain't the machine my 32s or my 32sII were.

The 48 was a datacollector, calculations were done with the 32s' back in my day. You will hear talk about 41's, but those guys are posting from the nursing home 😀

I [ENTER] RPN [ENTER] HATE [ENTER]
Seriously, who thinks like that? Why should change the way I think to accommodate what used to be the limitations of technology which is by now ancient. Just because you we're forced to learn RPN 30 years ago, while being hazed as rear chain-man, does not mean any of that was necessary. Surveyors seem to have developed a sort of Stockholm syndrome in regards to RPN. Of course I could be completely wrong, put posting anonymously allows me to be obnoxious without fear of repercussions.;-)

> Just because you we're forced to learn RPN 30 years ago

36 years ago for me, but I wasn't forced -- when I was first shown RPN, it was like a light going on. It seemed completely natural, and still does. I do use an accountant-style calculator application for adding long columns of numbers (generally once a month when reconciling credit card statements), but returning to my HP-48 emulator (either on my PC or on my Android) feels like coming home.

RPN is much more efficient once you learn how to use it.

I started with standard calculators. In the mid 1990s a Survey instructor got the class a deal on HP32SIIs. Most didn't like it but I figured it out in about 15 minutes and have preferred it ever since.

Thanks for your responses, folks. Much appreciated. 🙂

1. Heresy. Nothing is stupider than trying to enter an equation on a non-RPN caluclator using parentheses keys.
2. You're not as anonymous as you think you are.

I'm sorry, I think you meant to say "HATE [ENTER] RPN [+] I [+]

I like RealCalc for Android.

> 1. Heresy. Nothing is stupider than trying to enter an equation on a non-RPN caluclator using parentheses keys.
People keep saying that, but it doesn't seem to be a problem for me. If it is too convoluted, I program it into my calculator. If it wasn't so easy to program a calculator, I would probably have to write everything down first, though, and then key it in.
> 2. You're not as anonymous as you think you are.
I know, and I don't worry about it. I was just poking fun at myself for the tone of the post. I just can't wrap my head around RPN. If it works for you, great.

See! I told you I couldn't figure it out. It's all reverse-Polish to me...
