User Interface (UI) and User Experience (UX) are two important components of an application. They are usually placed together because they are the front end of an application which lets a user like an app and communicate with it. However, both have their own importance in an app and perform different functions.
What is UI Design?
User Interface (UI) is the appearance of the application, which is visible to the users. The user interface is the graphical layout of an application which consists of buttons a user can click, textboxes a user can type on, and a set of images and graffiti to either deliver related information or to add to the interface of the app. It includes screen layouts, transitions, and interface animations and every single micro-interaction between the user and the application. All sorts of visual elements, interactions, or animations are designed by designers and developers. The UI designers should be creative and vividly imaginative to come up with unique interfaces for each app.
What is UX Design?
User Experience might sound the same as UI, but it is completely different. It is mostly a back end process which determines how the application will interact with the user. UX should be smooth navigation between all the functions of an application. If the application is efficient and runs smoothly, it gives the user a much more efficient experience as the time of a user is the most valuable thing. User experience is determined by its ability to interact with the user interface elements created by UI designers.
UI designers also assist the UX designers in creating an interactive platform, which is why they are confused for being same. But the UI designers decide how the UI will look, whereas the UX designers are the ultimate in charge of how the UI will operate.
