High technology meets high style with Guess's cross-platform Xamarin apps

Some people think choosing cross-platform frameworks for app development comes at the sacrifice of user experience and stylish design. Those people probably haven't used GUESS's suite of apps. Using Xamarin as the foundation, efficiently ArcTouch built apps for three brands that are part of global lifestyle company GUESS's portfolio. And the company's mobile revenue has since seen a dramatic lift.
