Clean RPN is a simple and clean RPN calculator. Unlike other RPN calculators which try and mimic the appearance 30 year old desk calculators, clean RPN takes advantage of the screen space and rich input that your phone or tablet provides. The results of your calculation appear while you type and a scrollable list of previous calculations allows you to easily keep track of your history.

Features:
• Perform calculations using RPN - Reverse Polish notation AKA postfix notation
• Results appear as you type your calculation - no need to press enter
• Scroll through a list of history
• Tap on a result from your history to include it in the current calculation
• Support for tablets and phones
• Share your history via e-mail, etc
• Use custom number and function key boards to build your calculation - or your devices built in keyboard
• Wide number of mathematical functions supported

Mathematical functions supported
◦ Multiply, Divide, Subtract and Add
◦ Sin, Cos, Tan,
◦ Shin, Cosh, Tanh
◦ Arc-Sin, Arc-Cos, Arc-Tan, Arc-Tan2

Best I could find This is rpn, and its also really great. easy to use once you realise how it works!

#### Callum King-Underwood

Not immediately obvious I expected that hitting the enter button would push a number to the stack and that the operator buttons would perform operations on that stack as with other RPN calculators (real ones, not just apps). This was not the case. Once I worked out I had to put the entire expression on one line it was fine

#### Jeff Hillman

Not RPN Just another algebraic calculator.

#### Mike Lipphardt

Not RPN, sorry It just isn't. Putting an algebraic expression on a line isn't RPN.

#### Kevin McCarthy

Meh Doesn't have a stack. You have to put the entire expression on one line which seriously hampers the way I use an RPN calculator. It works as the author intended, but I suspect the author never used a real RPN calculator before.

#### Paul Stickney

Not the 'good kind' of RPN Instead of being based around a stack, the RPN only applies to the current equation written on one line separated by spaces. The value is computed when enter is pressed. This also means there is no support for dup, roll, etc.
