Xamarin turns you into a multi-platform mobile developer virtually overnight.

Xamarin apps look and feel native because they are.

Native User Interfaces

Xamarin apps are built with standard, native user interface controls. Apps not only look the way the end user expects, they behave that way too.

Native API Access

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.

Native Performance

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.iOS

The best way to build native iOS apps.

  • Ship native app bundles on the App Store.

    Our Ahead-of-Time (AOT) compiler compiles Xamarin.iOS apps directly to native ARM assembly code, meaning your app is a native platform binary.

  • Access any iOS API.

    We bring 100% of Apple’s iOS SDK to C#, enhancing Objective-C APIs with stronger types and .NET naming conventions so you feel right at home.

  • Call existing Objective-C code from C#.

    Use your existing Objective-C code, frameworks, and custom controls in your Xamarin app using our automatic binding generator.

  • Build WatchKit apps.

    Use Xamarin Studio or Visual Studio to build new Watch Apps, edit Watch user interfaces in the iOS Designer, and debug Watch apps in the iOS Simulator.

  • Stay up-to-date with Apple.

    We released same-day support for iOS 5, iOS 6, iOS 7, and iOS 8 so your apps can take advantage of the latest iOS features as soon as possible.

Xamarin.Android

The best way to build native Android apps.

  • Ship native Android packages.

    Xamarin.Android uses just-in-time compilation for sophisticated runtime optimization of your app’s performance, meaning your app is a native Android APK.

  • Access any Android API, including new form factors.

    We bring 100% of Google’s Android APIs to C#, enhancing Java APIs with async support and .NET naming conventions so you feel right at home.

  • Call existing Java code from C#.

    Use your existing Java code, frameworks, and custom controls in your Xamarin app using our automatic binding generator.

  • Build Android Wear apps.

    With access to 100% API support for Android Wear, create full-featured applications capable of running on Android Wear devices.

  • Stay up-to-date with Android.

    Xamarin stays up-to-date with the most current APIs from Google, so you can always use the latest features in your apps.
