I clicked hoping this would be about how old graphing calculators are generally better math companions than a phone.

The best way to do math on my phone I know of is the HP Prime emulator.

I run a TI 83+ emulator on my Android phone when I don't have my physical calculator at hand. Same concept, just learned a different brand of calculators.

built-in calculator apps are surprisingly underbaked... I'm surprised neither of the big two operating systems have elected to ship something comparable to a real calculator built in. It would be nice if we could preview the whole expression as we type it..

I use the NumWorks emulator app whenever I need something more advanced. It's pretty good https://www.numworks.com/simulator/

That’s certainly an improvement - but why can’t I modify a previous expression? Or tap to select previous expressions?

What I want is something like a repl. I want to be able to return to an earlier expression, modify it, assign it to a variable, use that variable in another expression, modify the variable and rerun and so on.

I think on the numworks you can use the arrow keys to pull up an old expression. I think it would be really cool if someone built out an interpreted, nicely rendered calculator language/repl that could do variables and stuff. Might be an interesting idea
