Not getting the answers you need out of your standard mobile calculator? Then perhaps you need something a little smarter. MxCalc gives your mobile the brain boost it needs to solve scientific calculations, and it specialises in financial mathematics - so you don't have to.
It comes with everything you'd expect from a scientific calculator supporting forces, powers, trigonometry; all those equations you dreaded at school. There are more than 130 built-in functions, and that should be enough for anybody.
