A splash screen is a graphical element that appears when a software application or website is loading. It typically displays the logo or branding of the application, along with a loading animation or progress indicator. This screen serves to inform users that the application is starting up and helps create a visually appealing first impression. Splash screens are commonly used in mobile apps, video games, and desktop software. They can enhance user experience by providing a brief moment of anticipation while the main content is being prepared. However, they should be designed to disappear quickly to avoid frustrating users with long wait times.
