C# is one of the best languages used to build cross-platform(iOS/Androids/Windows) mobile app development for all the platforms. And Xamarin is unique in a way which allows one to develop an app in C#, class library and run-time, that works across all platforms ie. Android, iOS and Windows. Using Xamarin and C#, native applications can be compiled that work well enough even for demanding games.
Build Better Apps with Xamarin
Share code across all platforms: Make apps for platforms like iOS, Android, Windows and Mac with a single, shared C# codebase.
C# is the best language for mobile app development: The entire app is written in the C# and the code can be shared on iOS, Android, Windows, Mac and more.
Native UI, native API access & native performance: The apps made in Xamarin focus on using the standard native User Interface for a better User Experience.
