The terms User Experience (UX) and User Interface (UI) have become inadvertently misused in the design community. The user interface is not the same thing as the user experience. This confusion most likely stems from the overlap of the skill-sets and tools involved in both disciplines.
Mobile-App-Design
It’s nearly impossible to extract the UX from UI and vice versa. While the UX is a combination of tasks focused on optimization of a mobile app for effective and enjoyable use, the user interface design is its complement, the look and feel, the presentation, and overall interactivity of a product.
UX design essentially helps users accomplish functional tasks across platforms and services while the UI design consists of compelling and aesthetically pleasing interfaces in which the user interacts with. UX and UI designers work in the same realm and on the same projects, but apply their own skills at various stages of development.
Why is UX Design Important?
Generally, a mobile app’s UX influences how users perceive it. Users often ask themselves if the app provides them value, if it’s easy to use, and if it will help them fulfill their goal. The answer to these questions should always be “yes”. The UX ultimately determines if a user will return to your app or if they will delete it altogether, and possibly giving it a poor rating.
