F# executes on a broad range of app and gaming platforms such as Android, iOS, Mac OS X, JavaScript/HTML5 and Windows. Its concise syntax, interoperability with .NET libraries, and its ability to manage complexity of components such as state machines, calculation engines, and more make it an ideal tool for many aspects of game and app development.

In addition, F# has excellent support for managing the server-side of games or apps. This provides a compelling story of full stack development with a single language for both client and server. See the Web Programming and Cloud section for details of using F# with server-side technologies. For example, F# is used on the server-side of one of the largest Facebook social games, as described in this interview.
