A mobile application (or mobile app) is a software application or mini programme designed to run on smartphones, tablet computers and other mobile devices. They are usually available through application distribution platforms, which are typically operated by the owner of the mobile operating system, such as the Apple App Store, Google Play, and Samsung Store.  Many Smartphones come with apps already installed to implement basic functions and utilities such as email, internet, messages, contact books etc.  Additional apps (mini programmes) can then be installed by the phone user to help implement actions that they would like their phone to be able to do.  Some apps are free, while others must be purchased.   

Mobile apps were originally offered for general productivity and information retrieval, including email, calendar, contacts, and stock market and weather information. However, public demand and the availability of developer tools drove rapid expansion into other categories, such as mobile games, factory automation, GPS and location-based services, banking, order-tracking, and ticket purchases. The explosion in the number and variety of apps made discovery a challenge, which in turn led to the creation of a wide range of review and recommendation sources, including blogs, magazines, and dedicated online app-discovery services
