Calc RPN App Reviews

This application is the rpn calculator application I have been looking for. Because it is simple and has large easy to hit keys. It provides 4 registers. It has a clear key. It provides a store and recall function that is easy to use. I would recommend this app to anyone looking for a non scientific simple calculator utilizing the rpn input format.

I was just looking to replace Apples default calculator app that had RPN functionality. This app does just that. If youre looking to do complex or scientific calculations, this wont do it. But for $1 its a good simple replacement. One minor gripe is the audible click, if you choose to turn it on, is too loud and should be a more subtle sound.

Shows a poor concept of how RPN should work. Have to use the subtraction key to enter a negative exponent. Have to enter 0 before the decimal for fractional values. Cant see an exponent entry until it is to late.

The app has not loaded since I installed 9.2 update.
