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.

    This app is slow 🐌 you need more improvements to faster work. You should add a backspace button.

    It's very good and useful. It can save your results. Only one thing need a button to delete a number rather than deleting all to repeat.
