May I ask what's your use case? A basic calculator covers about 95% of my needs especially on a phone.

Wait I'm genuinely curious: what's wrong with Calculator?

RealCalc is my favorite. It supports RPN and doesn't require any permissions other than storage.

Emacs Calc. Mind blowing in features and power. As for the UI . . . well, it's Emacs.

my favorite calculator app is emacs's calc-mode, it is probably one of the nicest RPN calculators on desktop

This is a desktop calculator for my personal use. I would like to know what you think and what would make this calculator useful for you.
