Description
Students and scientists from the 1980s will remember the classic RPN scientific calculators. These calculators strike a perfect balance between functionality and complexity.
* Complex number arithmetic and trig functions
* Matrix calculations
* Numerical root finder
* Numerical integration
* Statistical functions, linear regression
* Fully programmable
This app is completely free, no ads or extra bits to buy. I love this calculator and I like to share.
What’s New
Version 1.1
This app has been updated by Apple to display the Apple Watch app icon.
Updated 64 bit build that will survive long past the next iOS update.
Also, the calculator display now scales correctly for all iPhone screen sizes.
The name of the app has been changed to "Retro 15C". It's still free and always will be.
Thank you for your support!
Ratings and Reviews
Still works for me!
I’m at iOS 14.4 and the app still works.
Garbage
The interface is like a fuzzy JPEG.
Won't save data
Very nice app, except for one very important thing: it won't save anything, which means that any setting, register value or program is lost when the program is closed, which makes this app pretty much useless beyond basic arithmetic use...
