Mobile Application

Overview

A mobile applications is a computer program designed to run on a mobile device such as a phone/tablet or watch.
Mobile applications often stand in contrast to desktop applications that run on desktop computers, and with web applications which run in mobile web browsers rather than directly on the mobile device.

Google Play

Google Play (formerly known as the Android Market) is an international online software store developed by Google for Android devices.
It opened in October 2008.[16] In July 2013, the number of applications downloaded via the Google Play Store surpassed 50 billion, of the over 1 million applications available.
As of September 2016, according to Statista the number of apps available exceeded 2.4 million.
The store generated a revenue of 6 billion U.S. dollars in 2015.

App Store

Apple's App Store for iOS was not the first applications distribution service, but it ignited the mobile revolution and was opened on July 10, 2008, and as of September 2016, reported over 140 billion downloads.
The original AppStore was first demonstrated to Steve Jobs in 1993 by Jesse Tayler at NeXTWorld Expo[18] As of June 6, 2011, there were 425,000 applications available, which had been downloaded by 200 million iOS users.[19][20] During Apple's 2012 Worldwide Developers Conference, CEO Tim Cook announced that the App Store has 650,000 available applications to download as well as 30 billion apps downloaded from the app store until that date.
From an alternative perspective, figures seen in July 2013 by the BBC from tracking service Adeven indicate over two-thirds of apps in the store are "zombies", barely ever installed by consumers.

Microsoft Store

Microsoft Store (formerly known as the Windows Store) was introduced by Microsoft in 2012 for its Windows 8 and Windows RT platforms.
While it can also carry listings for traditional desktop programs certified for compatibility with Windows 8, it is primarily used to distribute "Windows Store apps"—which are primarily built for use on tablets and other touch-based devices (but can still be used with a keyboard and mouse, and on desktop computers and laptops).
