Mobile phone application or mobile app is a software designed to work on smartphones, tablets and other mobile devices. Many mobile applications are pre-installed on the device itself or can be downloaded to it from online application stores such as the App Store, BlackBerry App World, Google Play, 1mobile market, Windows Phone Store, Yandex store and others for free or paid version.
Initially, mobile applications were used to quickly check e-mail, but their high demand led to the expansion of their assignments in other areas, such as games for mobile phones and GPS, communication, video viewing and Internet use. The market for mobile applications is very advanced today and is growing steadily. The term "App" has become very popular since 2007, and in 2010 was added to the "Word of the Year" list of the American Dialectical Society.
