ND1 is an advanced, programmable RPL/RPN calculator that can calculate with numbers, complex numbers, fractions, vectors, matrices, strings, images, algebraic expressions, and other types of objects.
Over 500 operators deliver a total of over 2,000 functions across all object types.
In many ways, ND1 is a modern day update to the RPL calculator line from HP (28, 48-50g).
Try ND0 before you buy, if you're unsure ND1 is for you.
There's plenty of documentation for ND1.
Please see the support website for full specs, a "Quick Tour", tutorials, reference documentation, and a discussion forum, where support can be found.

The Future of Calculators
This is a wonderful app. Very deep. The dev has made some great improvements to the ui. An amazing value compared to a top of the line scientific calculator.
This app is a mess. Keys are in the wrong place. Even Apple's calculator is better...
Very Nice and Extremely Ambitious
This application cannot be fully appreciated until reading thru the wealth of documentation, reference material, tutorials. It also has a robust support group with contributed code.
You could teach math with this as well as teach programming. My first programming course in 1978 was on an hp 97 programmable calculator in RPL. And my first high end programmable was the hp 41CV in 1981. So this app brings back many good memories. And what the developer has added above and beyond these classic calculators is amazing. Unlimited stack, almost any kind of datatype you can imagine. Truly amazing.
Try the free ND0 and when you see how much you like it move up to this full version.
There are issues but the developer responded to me within hours of me sending an email to support.
