Description from store
This is a simple calculator inspired by last century Hewlett-Packard calculators.
The calculator supports keyboard input, simple operations and an infinite stack. Does not support infix input (but that's a feature).

- (2017-01-10) Robert M. Papillion: I agree with others that lack of support for a backspace/delete, sign change, roll-up/-down make this app hard to use. I like that it works with a touchscreen. But the buttons need to be about twice as big in the vertical direction for my fingers to hit them accurately! I will have look for an RPN calculator that's more complete.
- (2015-11-06) Jeff Martens: Enter doesn't work. E.g., if I want to add 4 to 4, I should to hit 4, enter, enter, +. But the second enter doesn't work. The left arrow would be clearer as CLx, and the up-down arrows don't roll the stack down (my first guess), but implement x<->y. My guess is the author has never used an RPN calculator.
- (2015-05-27) Alexandre Rousseau: Would be perfect -- good UX -- were it not for the currently blurry icon. EDIT: on OSX, once in the calculator app, alt-tabbing back to Chrome does not work. IOW, if all your Chrome Windows are minimized, there is no way to get back to Chrome without stopping and relaunching the app. This is a serious bug. Downgrading from 4 to a 2. EDIT: no support for backspace/delete key, rendering editing of entered numbers impossible. No keyboard support for negation. Arrow key support for stack navigation would be nice too. Won't use this app for now.
