Uno Calculator

The Uno Calculator is a port of the Windows Calculator to C# and to the Uno Platform for iOS, Android and WebAssembly.

The app provides standard, scientific, and programmer calculator functionality, as well as a set of converters between various units of measurement and currencies.

The Uno Calculator will regularly follow with the Windows Calculator updates. You can get it from the App Store, Play Store, in your browser, and of course the original calculator on the Microsoft Store.
