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.

• 125 mathematical and physical constants
• statistical functions for memory values

    Extremely handy tool.

    First of all, I'd like to mention that the idea of creating such a calculator suite (although I don't know whether this idea originated with the creation of this software), with separately designed calculators for different fields of study, is very practical, because it avoids a user interface overfilled with layered functions (we've all used professional calculators where each key has at least two more sub functions which need to be activated via shift keys etc.). That being said, this calculator suite offers for each individual calculator the most beautiful user interface I've ever seen on any software or hardware calculator (and I'm a proud owner of a Casio PRIZM). However, each calculator performs its operations smoothly and highly precise. In short, brilliant software. My special thanks to the developer, for making this outstanding app freely available to everyone.

    WARNING!! This app requires access to FAR more data and decices on your phone than it reasonably needs to function - your identity, microphone, location and movement, photos, and more. This is a potentially serious privacy issue. Let the buyer beware...

    Has everything you can think of in it. Much better than the default calculator.
