Factors like page load speed, responsive design, and efficient resource management can make or break the user experience. Many developers are now leveraging techniques such as lazy loading, image compression, code splitting, and using content delivery networks (CDNs) to improve responsiveness. Progressive Web Apps (PWAs) are also gaining traction for their ability to deliver native-like performance on mobile devices. Companies offering Web App Development Services often emphasize mobile-first design and performance audits to ensure apps run smoothly across devices and networks.
