looks great, downloading now!
I uninstalled the stock calculator forever ago in favor of RealCalc, because of the crippled functionality of the stock calculator. My first thought when i saw this app was "hey! i can finally replace realcalc with something less ugly!" bat, sadly, i'm keeping realcalc.
you have an awesome app here, devein, but for it to replace realcalc for me, you'll need to add exponent and root (eg, square and cube roots, not android roots :P) functions.
That being said, it IS a wonderful app, and i know a lot of people will love it.
