RPN calculator

Does what I need. It has more functions but I really love RPN for basic arithmetic and that's good enough for me.

Perfect!

Sweet Nice for those that want an RPN calculator.

Almost perfect The thing I might object against is the placement of the enter button. I would have preferred it to be horizontal rather than vertical for easier reach. But that is a very minor complaint.

Too big on a 10" Tablet Would Be nice as a popup floating half-screenapp. as a full- screen, it's too big on the buttons,too small on the text.

Nice, simple RPN calculator So, I have RealCalc, which offers an RPN mode, but for the life of me, I can't understand why it duplicates your entry in both x & y every time you hit enter. The result is that you have to remember to use an operator on your last entry, rather than hit enter and then use an operator. So I went looking for a simple RPN calculator for my everyday (non-scientific) needs, and this one works very well for that purpose. My rating of five stars is based on the fact that it serves the purpose it was intended for - a simple RPN calculator - very well. It has a multi-line display, and <enter> behaves the way I think it should. And it's free (open source, also!) Thank you!

Great App! Thank you so much for developing and then giving away this app for free! It satisfies my needs nearly perfectly. Maybe consider an UNDO?

Simple Multi-line RPN Calc This is a simple but effective multi-line RPN calculator. The simplicity reduces the key count and thus makes it easy to use on a small screen--unlike apps that are clones of HP scientific calculators. On my Galaxy Note II this isn't an issue, but I could see it being one on other phones.

The Best for simple calculations I'm used to rpn in my HP, but in my phone I don't need that much power and complexity. This app behaves as I'm used to but keeping it simple.

Great Would like to disable vibrate. Also, would be nice to automatically adjust decimal display to entered significant figures.
