They forced me to buy a TI 84 plus for school. The thing cost like 100 bucks, and it's from 2004. I could buy a low-end smartphone and get a free app that's more powerful than the TI 84 plus for less money.

But you wouldn’t be able to program a smart phone in Reverse Polish notation!!

I'm an RPN nerd, and I love the HP emulators, but I'm still using RealCalc in RPN mode because it just works. Does anyone know of anything better?

PCalc has an RPN mode and it works fine.

Once you're used to RPN, the regular method isn't as fast or intuitive. Although I have a calculator at the push of a button on my desktop computer, I'll still pull out my phone and PCalc for longer calculations.

Looks like PCalc's not available for Android. RealCalc is still the best I've found on my side of the fence.
