Skeleton screens are an effective technique to enhance the perceived performance of mobile applications by displaying a skeletal outline of the content while it loads, making the app feel faster to users. Unlike traditional loading spinners, skeleton screens provide users with a preview of the page layout and allow interaction even before the content is fully loaded, resulting in a smoother user experience. Implementing skeleton screens is straightforward using HTML and CSS, particularly in the Ionic-Angular framework, which offers tools like the ion-skeleton-text component to simplify their creation. This approach, when combined with traditional performance optimizations like lazy loading and code splitting, can significantly improve an app's responsiveness and user satisfaction.
