A mobile application, often called a mobile app, is a software program designed to run on smartphones and tablets. These apps can be downloaded from app stores, such as the Apple App Store or Google Play Store, and serve various purposes, including communication, entertainment, productivity, and more. Mobile applications can be native, meaning they are built specifically for one platform, or cross-platform, which allows them to work on multiple operating systems. They enhance user experience by providing convenient access to services and information on the go, making everyday tasks easier and more efficient.
