When Fluent launched on Windows 10, it gave Microsoft's aging operating system new life through modern, clean interfaces.
But until now, Fluent only influenced the appearance of Windows 10, not the Microsoft apps and add-ons found on other platforms. With the release of new toolkits for iOS, Android and the web, developers can now create native apps on non-Windows devices using the Fluent design language.
The goal for Microsoft is to give users a unified experience across devices and ecosystems. These visual changes won't be immediate, but Windows 10 users will start to see familiar design elements --- translucent effects, motions and depth --- on iOS and Android apps as well as web add-ons in due time.
