For a website, the first impression counts! How it looks is important in grabbing customer attention and turns them into loyal customers. No matter how good the website or app functionality is, it has to be impressive in terms of look and feel as well. UI and UX play a vital role in Web and mobile applications, where UI refers to user interface design and UX refers to user experience design. UI is all about how the website is designed and it goes hand in hand with graphical design. UX design is more analytical and is all about improving the user satisfaction, usefulness of website and the ease of use between the user and the product. User experience encompasses all characteristics of end users interaction with the brand and services provided by it.
