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.
