A typical mobile application uses a network connection to communicate with distant computing resources. Creating software programs that run on mobile devices is known as "mobile application development." As a result, the mobile development process entails developing installable software packages, integrating backend services like using an API to get data, and testing the application on the intended devices. Mobile user interface (UI) design is equally crucial for producing mobile apps as part of the development process. Contexts, screens, input, mobility, and limits are all considered while designing for mobile devices.
