Programmable calculator for iPhone

With all the computer power of an iPhone, I can find an app that let me do some simple programming like a Texas Instrument SR-56 programmable calculator.

PockEmul?

For something less retro, there's: www.maplesoft.com/products/MapleCalculator/ - but that's not programmable.
Dunno why. Modern phones are easily powerful enough to run Maple or Mathematica.

PCalc allows for custom functions.

Soulver 3 - Notepad Calculator App for Mac & iPad is a lighter duty app for defining and solving problems. It’s a different approach, but I’ve used it to create useful worksheets.

Man, when I was in my 20’s and there was no such thing as a laptop (or smartphone) EVERYONE had an HP-12C even if the only thing you could do with it was to add 3 numbers. My wife, an engineer, had some entirely opaque (to me) programmable HP calculator

I too am curious why iPhones don’t have a plethora of “programmable calculator apps.” I settled on the idea that business folks and engineers just use their laptops for “on the fly” calculations these days and therefore the market for an iPhone app like this would be very small.

Another vote for PCalc.

If you’ve outgrown the user interface of a programmable calculator, and have an iPad, you can use Swift Playgrounds from Apple which is a friendly environment for beginners.

I owned a TI58, a successor to the SR56 with a built in magnetic strip recorder for storing programs and a printer. I used it in the late 1970's for building some quite complex financial spreadsheet. The magnetic strip reader failed after a couple of years which meant that I had to input each program by hand.

Somebody else has mentioned the HP12C. I used one for at least 15 years until the display failed. It was small and had a superb keyboard and a very good display. I have never found as good a replacement, even my iPhone😁.

I have no experience with this application but it came up in a search:

I41CX

For IOS there is the i48 HP48GX RPN emulator which I just use as a scientific calculator but prefer to use the real thing which I still have.

I see that MATLAB has a mobile version.

Personally I gave up trying to program anything on a mobile app a long time ago - the days of the Dell PDA mobile eindows handheld. I prefered the desktop apps ( ie a proper keyboard ) in the days when I was doing engineering stuff.

Another emulator for iOS is i41CX+ which I love, having cut my teeth on a real HP41C. It's layout quite closely resembles the real thing, very easy to use.
