UX Design refers to the term User Experience Design, while UI Design stands for User Interface Design. Both elements are crucial to a product and work closely together. But despite their professional relationship, the roles themselves are quite different, referring to very different parts of the process and the design discipline. User experience (UX) refers to any interaction a user has with a product or service. UX design considers each and every element that shapes this experience, how it makes the user feel, and how easy it is for the user to accomplish their desired tasks. UI design is the look and feel, the presentation and the interactivity of a product.
