UI Design The “Invisible” Work That Makes Apps and Websites Feel Easy

UI design—short for user interface design—is one of those things you don’t notice when it’s done well. You just move through an app, find what you need, tap a button, and everything feels… obvious. But when UI design is off, you feel it immediately. You’re hunting for the menu, you’re not sure what’s clickable, the text is hard to read, and you start getting that quiet frustration that makes you close the tab and never come back.
