The user interface (UI) design is one of the most important building blocks of digital products and services. The first contact the user has with the product is visual language, and this first impression directly determines the perceived quality of the product.
A good interface is built on a consistent design system, a clear hierarchy of information, and interactions that serve the purpose. Every item added to decorate is an obstacle on the way to the user's goal.
A useful interface helps people complete tasks through clear, consistent steps. Visual decisions should be evaluated alongside readability and interaction states.
