App Development refers to the process of creating software applications for various platforms, including mobile devices, desktops, and web browsers. It involves several stages, including planning, design, coding, testing, and deployment. Developers use various programming languages and tools to build applications that meet user needs and provide a seamless experience. In recent years, the demand for mobile applications has surged, leading to the rise of frameworks like React Native and Flutter that allow developers to create apps for both iOS and Android from a single codebase. This efficiency not only saves time but also reduces costs, making app development more accessible to businesses of all sizes.
