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.

    Love this app! I use it all the time and would be lost without it. The scientific calculator and currency converter are especially useful. I travel a lot, and it is so helpful to be able to add up what things cost in both my own currency and the one of the country I'm travelling to. The search functions within the calculators are really handy too. And the design is great - a very polished app. I've tried several calculators out there but this one is by far the best!!

    Good app, but I don't appriecite paying to remove ads for them to come back later on, waste of money. Surely by doing that the app violates terms and conditions?!?!
  • by Robert 19/02/2015
    Good but adverts keep reappearing - needs fixing!
  • by David 17/02/2015
    Same as others I paid for full version now after update the ads are back. A big scam.

    Bardzo dobry kalkulator. Cztery gwiazdki tylko dlatego bo nie ma rzeczy doskonałych 😃 i gdyby nią był prawdopodobnie byłby płatny.
