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.

Hmmm, kept giving me an error dialog on my iPhone 6+

Not sure what happened, but trying to run a simple program on it led to some error dialog continually popping up.

Works as expected and is free, no ads so far.

Just what I needed. It even can be programmed in the original way. However program execution is extremely slow, slower than on the original.

The other bummer is that programs seem to disappear. I was using one the entire day yesterday but today the program memory was cleared.

great app!

Fantastic app, all the functions of my trusty 15C on my phone.
It even has the formulas on the back!
Thanks for allowing me to have my 15C with me all the time.
