    Simply brilliant. My absolute favourite calculator app for Windows Phone. It has a wonderfully clean and simple GUI. The app is also multifunctional with a scientific calculator, a unit converter and a currency converter as well as other more advanced features. For those complaining about the ads after the update, just hit the buy button again. And don't worry, you won't have to pay again. It's a quirk of the Windows store.
