An app is a shortened version of the noun “application.” The term is primarily used in the fields of technology, more specifically in the computing, gaming and mobile market. The word “app” is used to identify a wide range of software.
Applications perform a set of routines and functions as defined by the end-user. An app may refer to many types of digital programs, including productivity, entertainment and educational products. The shortened term has become popular due to the rise of mobile devices, as their digital libraries and repositories adapted “apps” as opposed to “applications.” Apps are available in various forms and business models, including free of charge, via paid subscriptions and for a flat fee.
