I love this, great idea! I don't need the majority of the fancy features but I can see the use case for them. I built my own calculator app a while ago [0].

I built my own calculator app a while ago [0]. I've used an HP-41C as my main calculator for many years and I have not yet found a good RPN calculator app available on ALL platforms. I wanted a simple calculator that felt like an HP-41C that I can use on my phone + all desktop operating systems and get the same experience.

- layer8 5y agoI like it, except that the Enter symbol confuses me. I associate it with a windowing button or on/off switch. I probably would use ⏎ (U+23CE) instead.
- shhsshs 5y agoGood suggestion. I chose that symbol because it is literally called "ENTER SYMBOL" but maybe something more universally accepted would be better.
- jimbosis 5y agoHave you seen Free42, "...a re-implementation of the HP-42S Scientific Programmable Calculator and HP-82240 Printer?" [0] It is available for Android, iOS, Windows, macOS, and Linux. (At one point there was even a version available on Windows Phone 8.) Perhaps it checks your boxes of good RPN calculator, available on all platforms. I don't know how much an HP-42S feels like a 41C. In any event, thank you for ralc. I've off and on been searching for a nice web-based RPN calculator.
