I'll second the vote for RealCalc. It's extremely useful.
A moment of truth here. I'm a long term fan of HP reverse polish notation calculators. So RealCalc's RPN mode suites me just fine. Except for the amazing scientific calculators you can get for about $12 (mostly marketed to middle- and high-school kids), it's a wonder there's any market left for scientific or financial calculators. Smartphone apps are so powerful, full graphics and dirt cheap.
