Mobile app development refers to the process of creating software applications designed to run on mobile devices such as smartphones and tablets. It involves a variety of tasks, including designing the user interface, writing code, testing the app for functionality and usability, and deploying it on app stores like Google Play or the Apple App Store. Mobile app development can be divided into two main categories: native app development, which creates apps specific to a particular platform (iOS or Android), and cross-platform development, which enables the creation of apps that can run on multiple platforms using a single codebase. With the growing reliance on mobile technology, mobile app development has become a crucial aspect of business and entertainment, offering users convenient solutions and immersive experiences.
