Application

An application program (software application, or application, or app for short) is a computer program designed to carry out a specific task other than one relating to the operation of the computer itself, typically to be used by end-users. Word processors, media players, and accounting software are examples. The collective noun "application software" refers to all applications collectively.

Applications may be bundled with the computer and its system software or published separately and may be coded as proprietary, open-source, or projects.

The term "app" usually refers to applications for mobile devices such as phones.
