Calculator Free

The #1 calculator in the Windows Store with more than a million users worldwide. Named an "Editor's Pick" by Best Windows 8 Apps, and one of the highest rated apps in the Windows Store.

The #1 calculator app for Windows.

I'm Calculator Free - the perfect calculator for Windows. Snap me, turn me, or let me fill the whole screen with four beautiful nature themes. I'm easy to use and artfully designed to do things better than your desktop calculator ever did.

I love saving you time and effort. I easily Copy and Paste values to and from other apps. I always remember what you're working on, so if you need to quit and go do something else, I'll have it all waiting for you when you come back. Even better, my Live Tile updates constantly, so you can always see your last result at a glance, right from your Start Screen.

I'm attractive and effective and I make great use of your Windows display. If you feel like a change of scene, just tap one of the color theme buttons at the top of the screen.

Lastly, you can say goodbye to losing track of where you are in a calculation - I show you exactly what's happening at all times, in clear, elegant type. If you do make a mistake, use backspace to quickly correct it, instead of starting over

Try me today and finally put that desktop calculator to rest!
