Why is UX needed, if you can just design UI and that’s it?

This is one of the most asked questions. The UX stage is about how you feel when you browse a website or application while UI is how it looks. To put it simply, UX deals more with logic, connections and user behavior while UI provides a visual representation of the entire concept. It means that designers should first work on the UX part with much focus on layout, making it more powerful, thought-out, clear and easy to use. Without this initial first step, you highly risk creating a pure mess out of the user interface.
