Firstly, what do they all mean? UX stands for User Experience. UI refers to User Interface. IA means Information Architecture and IxD is a new set of initials to me, but apparently covers Interactive Design.
Team Starberry put a great deal of focus in all of these processes. They all contribute towards the design and development of our award winning websites and digital services.

So in an oversimplified and user-friendly nutshell, UX Design is how a user feels about the apps, UI Design is what, where and how elements work on the apps, Information Architecture is how a app is organized, and Interaction Design is how the user and app act and react to each other.
