Hi everyone - I’ve a recent interest in calculators which I’m pursuing. After an unfortunate experience with Droid48 (it’s hiding a chunky proprietary ROM in there without telling you clearly [shouldn’t have went near the Play Store]), I’m investigating other calculators.
What do you use? What’s the “most powerful” one which is also FOSS? I could be missing some heavyweights.
I’ve some experience with Emacs’ M-x calc, and am quite a fan, but having a portable one via the mobile phone is useful in some scenarios. I guess I’m a tad interested in the history of HP and TI machines, so was veering towards emulators of those, but they’re all proprietary it seems. HP for example seem to have the broadest selection of books - the HP48 has very cool books, which is why I was veering towards Droid48 originally.
I see that F-Droid has tons of options in any case. JRPN 16C is there, but it’s actually the “legacy” one, and for some reason the newer JRPN 15C and JRPN 16C aren’t packaged for F-Droid. What’s going on there, if anyone knows?
I should maybe mention “microMathematics Plus” too, which definitely seems serious.
Anyway, all points and experience welcome.
