Cyber-Psycho-Sis vivi 🕯️EDIT: qalculate does what i want, thanks to everyone that suggested it
what's an android calculator app that doesn't suck
i want one with hexadecimal support. i should be able to input 32 + 0x1f and it just works
unit conversion would be nice too

🔜 HåckMas@vivi I'll also recommend qalculate
See https://f-droid.org/packages/com.jherkenhoff.qalculate
Does base conversion, unit & currency conversion, even implicitly, so you can add, subtract, multiply, divide etc many measurements with different units and it just figures it out.
It's a lovely app, also available as a GTK version for desktop (I'd recommend that one) and a Qt version (imo looks worse, even on KDE)
