The User Interface (UI) is the front-end of a product that the user interacts with. The UI is anything that the user can see and select to operate the product or application.
Though some people use UX (User Experience) and UI interchangeably, they are related but distinct categories. UI is a vital aspect of digital adoption. The look and feel of a product goes a long way in making a first impression.
Good UI should anticipate the user's needs and provide them with a way to engage with the platform or software in an almost invisible manner.
The benefits of well-done UI are:
Customer acquisition
Lower customer support
Increased customer retention
