Xamarin is a Mobile App Development and App creation software. Xamarin tools are used to write native Android, iOS, and Windows apps with native user interfaces and share code across multiple platforms, including Windows and macOS.
Xamarin apps are built with standard, native user interface controls
Xamarin apps have access to the full spectrum of functionality exposed by the underlying platform and device, including platform-specific capabilities like iBeacons and Android Fragments.
Xamarin apps leverage platform-specific hardware acceleration, and are compiled for native performance. This can’t be achieved with solutions that interpret code at runtime.
Xamarin's Visual Studio App Center Automates the lifecycle of your iOS, Android, Windows, and macOS apps. Connect your repo and within minutes build in the cloud, test on thousands of real devices, distribute to beta testers and app stores, and monitor real-world usage with crash and analytics data.
