UX and UI design are both crucial in creating digital products, but they focus on different aspects:

• UX design is about orchestrating a holistic experience for users. It focuses on the overall journey that users go through. Key elements include understanding user needs, creating user flows, and testing usability. The goal is to provide a seamless and efficient interaction.
• UI design complements UX by focusing on the visual aspects. This involves crafting the screens, buttons, and icons — essentially, all the elements users interact with visually. UI design aims to elevate the product's aesthetic appeal and emotional impact.

In short, UX design concentrates on how users interact with the product, while UI design focuses on what users see and interact with. Both disciplines are vital, collaboratively ensuring a comprehensive and engaging user experience.
