On that note, I always end up using an HP 48g emulator on my phone as my main calculator app. I've been using Droid48 for many years now [0]. I'd initially looked at most of the native mobile calculator apps before realizing that since I was comparing them all with the HP 48 experience, I might as well just use an emulated HP 48 and be done with it.

On a laptop or desktop, though, I've come to use Emacs Calc [1] pretty heavily. There's a surprising amount of power in it. It's pretty cool to be able to do things like operate on matrices of symbolic expressions via a stack interface.

I find Hiper to be almost perfect for its clearer UI than a rendering of a real device and, especially, for its prominent binary and hex radix modes.

But it lacks the stack undo of the 48 emulators.
