Android calculator app recommendations with plotting and physical constants

[dipole]

So I just got a new android phone, and naturally I'd like to download a good calculator for it. Preferably one with good plotting functions as well as plenty of computing functions (and preferably one which can store physical constants!). Any suggestions? :)

Search the Android store for "RealCalc scientific calculator". Also, in case you aren't already aware, there's a Wolfram Alpha app available.

I'm a bit biased since I use physical HP calculators.

But my Android calculator app is Droid48 which emulates a HP48 scientific calculator.

I'm not sure about the physical constants, but maybe Maxima would be a good option.
