In the summer of 2011, Rdio found themselves with three different codebases for iOS, Android and Windows Phone apps for their internet radio service. In this highly competitive space, Rdio apps must provide a responsive, performant native user experience, and Rdio must iterate quickly with feature updates and bug fixes; a difficult task to accomplish across fragmented codebases.

As they researched cross-platform solutions, Xamarin stood out as the only solution delivering a fully native experience as well as the desired cost and time-to-market savings from unifying app development and sharing application code.

In December 2012, Rdio launch a major release to their Xamarin-based iOS and Android apps. Because the apps share more than 50,000 lines of code, Rdio was able to release updates for both platforms concurrently, and devote more time to new features and user experience.

�gTo our users, the most important thing is the performance and fluidity of the in-app experience. With Xamarin, we are able to have it all. We�fve saved thousands of engineering hours while delivering gorgeous, high-performance native apps across device platforms and form factors to consumers worldwide.�h
