Five reasons why we use Xamarin

As a Xamarin developer, Screenmedia can build better, faster, and more cost-effective apps

Efficient code use

Common code, such as business logic and workflow, can be shared across all platforms. This means less code is needed, leading to shorter development cycles and saving time and costs.

Fewer errors

By writing less code there are fewer bugs. One codebase also means greater test coverage from one comprehensive test instead of three largely duplicate tests.

Cost effective

One team, writing less code, using one codebase means Xamarin delivers high-quality, native apps at a lower cost than traditional native app development.

Faster release

Having one synchronised team on a single workflow means that more features can be built, and the app can be shipped through a single release.

Better velocity

One core development environment means skills can be concentrated and knowledge sharing and support improved across a single, larger team. This speeds up learning, which boosts team velocity.

Our work

At Screenmedia we work with some of the best large and small companies in the UK and have delivered a wide range of award-winning apps.


Xamarin developers code in C#, which is entirely native to iOS, Android, and Windows Phone. Anything that can be done in Objective-C or Java, can be done in C# with Xamarin.

Underneath the native user interfaces and platform-specific design language there is just one code base, which offers enormous efficiencies across the build, testing and maintenance of your app.

Xamarin development provides the advantages of native UI; access to specific-device features; and most importantly, native performance.

Purely Native

Purely native app development means developing in multiple codebases (Objective C, Java and C#).

A purely native approach means hiring and training a separate team of developers for each platform, each of which runs as a separate development stream and follows a separate roadmap.

With no code sharing across platforms, code is duplicated. This leads to higher development and support costs; delays the completion of all three apps; and forces platforms to be prioritised over each other for release schedules, excluding and frustrating users on the lower priority platforms. These limitations make purely native apps less appealing to secondary platform users, and limit or delay the innovation of important new features.

C# - there's no better language for mobile app development

Anything that can be done in Objective-C, Swift or Java, can be done in C#.

Its popularity speaks for itself

C# is a great programming language for cross-platform app development. It's a simple, modern, general-purpose, type-safe, pure object-oriented programming language.

Along with Microsoft’s .NET framework, developer needs are well taken care of using C#, making asynchronous programming a breeze.

It's easy to learn

C# is easy to learn, so it’s easier to build a team. Growing an experienced and effective mobile development team involves a steep and continuous learning curve; it’s hard enough becoming expert in one language without having to be expert across two or three.

Xamarin developers only need to learn C# and one core set of classes to be effective across Android, iOS and Windows Phone platforms. At Screenmedia we've found that experienced .NET/C# developers are immediately at home working within Xamarin because it's based on Mono (an open source version of .NET) and provides all of the available .NET class libraries developers are used to.

Quality and flexibility

Xamarin development provides the advantages of native UI, access to specific-device features, and most importantly, native performance.

Native User Interfaces

Xamarin apps are built with standard native user interface controls. Apps built with Xamarin look and behave the way end users expect, giving them a better and more satisfying experience.

Native API Access

Xamarin apps have access to the full suite of functionality afforded by any given platform or device. This also includes platform-specific capabilities, such as iBeacons.

Native Performance

As Xamarin apps are built for native performance, they are able to take advantage of platform-specific hardware acceleration. This can’t be achieved by apps which interpret code at runtime.
