Welcome to CNET Australia's App of the Day, where you can see some of the coolest, silliest and most useful apps in action.
A calculator with on-screen buttons? Pffft, everyone has one of those. For something really good, check out MyScript Calculator. It lets you write your calculations directly onto the screen via finger or capacitive stylus. It then translates your scrawls and performs the calculations, including mathematical symbols. It's not quite finished yet — it's not good at recognising letters, for example — but what it does let you do is just amazing.
