    I want to buy but seems pricey for something there are fee versions of. I've had the trial for a few months and have yet to see any updates... I like the button layout the best of the rpn apps.. Not crazy about colors and lack of settings. Almost identical to realcalc on android but less options

    Nice scientific RPN calculator. Enough features to be useful, and even has sufficient help screen explaining what some of the 'odd' keys are far.

    The operations that start with 0. don't work.

    Best Windows Phone RPN I've used. Red on gray is difficult for me to see.

    Nice app. Works like my old hp 11c. Would be nice to be able to change colors though, I have a hard time seeing the red "shifted" key labels.

    This is an excellent calculator. Please do keep the digit grouping display, the automatic updating for the history (This is noticeable when changing bases), and the seemingly unlimited stack quantity. There are a couple of things that I would like to see regarding calculation though. The first thing that I would like to see support for more significant digits (Windows' Calculator displays 32.). The second thing that I would like to see is higher values. It seems that the calculator encounters an overflow after........9.99999999999 * 10 ^ 208? (I am not sure what the exact value is, but it is probably somewhere in that general area). Windows' calculator encounters an overflow after 9.9999999999999999999999999999999 * 10 ^ 9,999. Inclusion of the comma for the scientific notation would be much appreciated as well. The application is well-coded and easy to use! Keep up the good work!
