Save Money

Xamarin cross platform app development allows developers to code once and rapidly deploy to all 3 major mobile platforms.

Save Time

With rapid development and deployment cycles, your new cross platform mobile app will be up and running in no time.

User Satisfaction

Our expert Xamarin mobile app developers can implement new features and bug fixes swiftly across all your devices at once.

Xamarin now has more than 15,000 customers in 120 countries, including more than One hundred Fortune 500 companies.

Traditionally, mobile app development meant taking into consideration all three major platforms: iOS, Android and Windows . This would require hiring developers for each individual platform, leading to painfully slow development cycles and delayed feature implementations due to coding, testing and deployment being repeated for each separate platform.

Thanks to Xamarin this protracted and expensive method of native app development, will soon be a distant memory!

Cross platform app development allows app developers to code once and deploy to all 3 mobile platforms quickly and efficiently.

With over 20 years experience in application development, we have lived through the tribulations of native app development and naturally embraced the Xamarin platform upon its initial inception in 2011.

Xamarin is now a part of Microsoft!

Xamarin has been heavily supported by Microsoft since the beginning and just recently Microsoft made the decision to acquire and integrate with Xamarin, showing their complete faith and full commitment to Xamarin as the Microsoft choice for cross platform mobile app development.

Xamarin vs other Cross Platform Frameworks

So how does Xamarin stack up against other popular cross platform app development frameworks such as Cordova, Appcelerator Titanium and Phonegap?

Thumbmunkeys (and Microsoft!) believe Xamarin is the premier solution for cross platform app developers for all of the following reasons:-

High performance

Cross platform apps can suffer from poor performance due to slow programming languages or bulky frameworks.
Xamarin is the notable exception among them, its performance is comparable and in some cases faster than native code.

Great UX

Your users will not be able to tell that your app was developed with Xamarin - the exact same user interface elements are used then for native apps.

100% native API access

With Xamarin, Apps have access to the complete range of functionality that is exposed by the underlying native platform and device. Xamarin apps also benefited from platform-specific hardware acceleration, which is a huge benefit over other hybrid platforms.

Code reuse

This is where Xamarin shows it's real strength - it is possible to achieve 100% shareable code across all major platforms with the Xamarin forms framework.

Strong industry backing

Xamarin has become one of the strongest cross platforms frameworks out there and with the recent backing of Microsoft it will only become stronger.

Large range of devices

Xamarin is not just for phones and tablets, it also works with wearable devices like WatchKit and Android wear.
