Mobile applications, commonly referred to as mobile apps, are software applications specifically designed to run on mobile devices such as smartphones and tablets. These applications can be downloaded and installed from app stores, such as the Apple App Store or Google Play Store, and are built to take advantage of the features and capabilities of mobile hardware, including touchscreens, GPS, cameras, and accelerometers.

Mobile apps can serve a wide variety of purposes, ranging from productivity tools and educational resources to games and social networking platforms. They are often developed using different programming languages and frameworks tailored for specific operating systems, such as iOS or Android. Mobile applications can be categorized into three main types: native apps, which are built specifically for one platform; web apps, which are accessed via a web browser; and hybrid apps, which combine elements of both native and web apps.

The rise of mobile applications has transformed how users interact with technology, enabling access to information and services on-the-go and enhancing the overall user experience in digital environments.
