The difference between UI and UX

User interface (UI) and user experience (UX) are two words that you might hear mentioned frequently in tech circles.

UI refers to the screens, buttons, toggles, icons, and other visual elements that you interact with when using a website, app, or other electronic device. UX refers to the entire interaction you have with a product, including how you feel about the interaction. While UI can certainly have an impact on UX, the two are distinct, as are the roles that designers play.
