Application development is the process of creating software applications that run on various devices, such as computers, smartphones, and tablets. This involves several stages, including planning, designing, coding, testing, and deploying the application. Developers use programming languages and tools to build applications that meet specific user needs. The goal of application development is to create functional and user-friendly software that solves problems or enhances productivity. It can involve different methodologies, such as Agile or Waterfall, to manage the development process effectively. Successful applications often undergo regular updates and maintenance to improve performance and add new features.
