RealCalc by Brain Overspill is the perfect calculator app when you need a little more calculating power than what the stock Android calculator can give. RealCalc has a simple user interface that is very streamlined and easy to use. One of the features I used most on RealCalc was the unit conversion functionality. The ability to do unit conversions in the palm of your hand is a surprisingly useful feature, which makes for one the best Android calculator apps available. Other features include percentages, Hexidecimal, Binary, Octal, trig functions in radians or degrees and a built in help feature. RealCalc is available as a free download on the Android Market or by clicking here.
