daggermoonTo the teachers who told me I'm not gonna be walking around with a calculator in my pocket all the time, suck it.
QuintusI use this a lot and love it a lot! The ROMs it emulates are very powerful calculators.
Also, there is a new project that brings Qalculate! to Android. You can find it somewhere here. It's also a powerful calculator and is more integrated to the system because it's not emulation.
TheTechnician27It's a shame Firebird doesn't seem to be on F-Droid. But Graph89 is really good for the older calculators!
Vendetta9076Genuine question, what's the usecase for this that I can't just do with my reg phone calculator?
Umm, It's an Emulator.
...right. But what does emulating a calculator get me vs just using the calculator app?
Most phone calculators lack things like graphs, statistical tests, etc. Really just for people who are quired to use Ti calculators or learned to use them in the past. Better apps imo exist (like numworks graphing calculator) if you don't have platform loyalty
TI is overrated. Play Store has the HP calculator emulators Droid48 and Emu48, but they're unfortunately not on F-Droid.

What matters is that TI has an effective monopoly on scientific and graphic calculators in the US in particular, which means that it's the platform that matters to most. It's irrelevant whether or not some alternative is better. It's also extremely widely supported by software and tutorials.
