Test your app on over 1,000 devicesRun your app on a huge collection of real devices from around the world. Select devices based on form factor, manufacturer, operating system, or even popularity in your target market.Automate using Ruby or C#With a framework called Calabash you can automate and test any iOS or Android app, native or hybrid, from the UI level down for perfect integration and continuous improvements.Analyze app performanceSee full-frame screenshots and video playback for every step of every test, then receive performance data and compare reports against previous runs to find regressions and bottlenecks.

Precise, detailed error reportingXamarin Insights helps developers prioritize issues by showing exactly which users each crash is impacting, and what sequence of actions preceded the crash.Understand how users are interacting with your appDevelopers can see who’s online, which devices they’re using, what issues they’ve experienced, where they’re from, and which activities they’ve used in sessions.Integrate your dataConnect your app to a variety of external services and be notified when a new issue is opened, an issue is occurring repeated times in a small amount of time, or an issue's status changes.

Xamarin apps share code across all platformsTarget iOS, Android, Windows and Mac with a single, shared C# codebase. Use the same language, APIs and data structures on every platform.C# is the best language for mobile app developmentAnything you can do on Objective-C, Swift or Java, you can do in C#Native UI, native API access, native performanceXamarin apps are built with standard, native user interface controls. Apps not only look the way the end user expects, they behave that way too. This can’t be achieved with other solutions.

C# as the language for your mobile app development

Stronger Types, Smarter ToolsGenerics guarantee that collections and other compound types are used safely, without the need for casts or comments. Xamarin tools understand intent better thanks to richer types, with benefits like ubiquitous code completion.

Anything you can do in Objective-C, Swift or Java, you can do in C#

Language-level AsyncAsynchronous programming (async) keeps apps responsive. In Objective-C, Swift and Java, async requires callbacks and manual bookkeeping. C#’s language-level support makes async a breeze.

First-class FunctionsIn Java for Android, lambdas are unavailable. In Objective-C, lambdas are extremly cumbersome. In C#, lambdas couldn’t be simpler, making functional programmers feel right at home.

Write C#. Run on 2.6 billion devices.With Xamarin, you write your apps entirely in C#, sharing the same code on iOS, Android,

Windows, Mac and more.
