I use [Free42](https://thomasokken.com/free42/) on all my platforms. Launches in an instant and has RPN.

Free42 is my favorite calculator on Windows, especially since I've long used HP's physical calculators. (Droid48 is also great if you're on Android.) But I still prefer PCalc on the Mac, because it's rather cumbersome to use a push-button calculator UI on a desktop computer with a mouse, and PCalc fits perfectly into the Mac user interface.

free42 is available for android as well

Qalculate (https://qalculate.github.io/) is quite good for linux/bsd

Indeed. Its command-line program (libqalculate, as qalc) also stands on its own, with comprehensive unit support and clear output.

I love that it has an easy "solve for x" function! I miss that from my good old TI-89.

IPython + qtconsole (https://qtconsole.readthedocs.io/en/stable/), with a config file that autoruns 'from math import *' on init.

That's alright too, but SpeedCrunch is much faster for simpler workflows

Thanks for that - Qalculate appears to resolve the problem I was having, finding a decent calc, similar to PCalc, but for Windows and Linux.

Love it! Thanks again.
