A questionably legal but terrific calculator is any TI-8x emulator for Android. I think as long as your own a real TI-8x and extract the ROM yourself, you can legally use the emulator. One of the emulators is called "Andie Graph".

Is it actually accurate without the hardware? I've seen graphical calculators go bonkers when emulated.

  I've never checked the accuracy. If he's emulating the hardware with 100% accuracy I wouldn't expect any difference in the output.

    Well that's the question good calculators have quite sophisticated "rounding error" fixes that ensure that large calculations don't end up being off by a light year, it's not just a simple question of rounding up/down because if you always do that staggering errors or even a short calculation with a large exponent can throw you quite a bit off.

I'm a big fan of hp calculators and use an emulated HP-48 most of the time.

  There is also a official HP Prime calculator.[0] Bit pricy but it somewhat easier to navigate than HP-48. Though it has limited RPN support... [0] https://play.google.com/store/apps/details?id=com.hp.primecalculator https://play.google.com/store/apps/details?id=com.hp.primeca...

  I still own a HP48gx and just love that thing. Alas, nowadays it's overkill. A bit like a Mack truck, which you use to drive 300 metres down the road to buy a pack of cigarettes. It's still one of my favorite gadgets, though.

    Overkill? Sounds like business as usual to me. On a serious note, you have to admit that the familiarity of the calculator helps. I don't know how much you're crunching numbers for complex calculations, but trying to get them to work on Wolfram Alpha or some other web calculator can be near impossible.
