The smart calculator for Windows Phone. Includes 5 unique calculators: Basic, Scientific, Programmer, Currency Converter, and Unit Converter.

Calculator² aims to innovate the pocket calculator by fully utilising the touch screen display of the Windows Phone. Calculator² incorporates the Modern UI and features large buttons for quick, error-free typing. Scientific functions, constants, memory items, currencies, and more are contained in comprehensive lists that are just one click away. Each calculation is shown in the display exactly as typed so that users can verify the input. The last 50 calculations are stored in the history with the option of using a result in the future. A unique memory solution allows multiple memory items to be stored and viewed simultaneously. The Currency and Unit Converters ensure that Calculator² is more than just a mathematical tool, and is great for everyday use beyond educational and work-related tasks.

    The app is a but sluggish to boot up even on the 1520 but has all the basic functions plus many more. Good app, but boot up times can be better.

    Well worth the moderate asking price. I've had more calculator apps on more platforms than I can count, and this is the first one that didn't have me wishing it had some feature or other. The only substantive complaint I have is that it takes overlong to switch amongst its five different modes, but that probably has as much to do with my low-end phone as it does with the app.
