App development for mobile devices, such as personal digital assistants, business digital assistants, and mobile phones, is referred to as mobile app development. This may refer to either the act of developing an app or the process of developing an app. These software programmes were developed specifically to function well on mobile devices, such as a smartphone or a tablet computer. These programmes may be pre-installed on phones during the manufacturing process of platforms, or they can be provided as web applications employing server-side or client-side processing (for example, JavaScript). Because of the high rivalry in the mobile software industry and the constant changes that occur within each of the platforms, application software developers must also take into consideration a wide variety of screen sizes, hardware requirements, and configurations. The creation of mobile applications has been showing consistent growth, both in terms of income and new employment opportunities. According to an analyst research from 2013, there are an estimated 529,000 direct app economy employment inside the EU then 28 nations (including the UK), with mobile app developers accounting for sixty percent of those positions.

The design of the mobile user interface (UI) is an integral component of the app generation process that takes place as part of the development process. When designing a mobile user interface, restrictions, contexts, the screen, user input, and mobility are all taken into consideration. The user is often the centre of attention during interactions with their device, and the interface consists of a combination of software and physical components. The ability for users to control a system is made possible by user input, while the ability for a device's output to reflect the results of user manipulation is made possible by device output. Constraints in mobile user interface design include restricted attention and form factors, such as the appropriate screen size for a user's hand while holding a mobile devices. Mobile user interface contexts convey indications from user activities, such as location and scheduling, that may be exhibited from user interactions inside a mobile app. Examples of this include a map of the user's current position and upcoming appointments. To provide a simple and straightforward experience for the end user is the primary focus of mobile user interface design. Mobile corporate application platforms or integrated development environments provide support for functionality (IDEs).

Mobile user interfaces, also known as front-ends, are dependent on mobile back-ends for the purpose of providing access to corporate systems. Data routing, security, authentication, authorisation, working off-line, and service orchestration are all made easier by the mobile back-end. A variety of middleware components, such as a mobile app server, mobile backend as a service (MBaaS), and service-oriented architecture (SOA) infrastructure, are what make this capability possible.
