The statistic below shows data on the number of apps available for download in leading app stores as of the third quarter of 2018. As of that period, Android users were able to choose between 2.1 million apps. Apple’s App Store remained the second-largest app store with almost 2 million available apps.

In 2016, the global mobile internet user penetration exceeded half the world’s population, while the average daily time spent accessing online content from a mobile device, such as a smartphone, a tablet computer, or wearable, had reached 185 minutes daily among Millennials, 110 minutes for Generation X, and 43 daily minutes for Boomers. Accounting for this popularity is also the growing creation and use of mobile apps, from gaming to fitness, over mobile messengers to animation software. Currently, the two largest global platforms for app distribution are Apple’s App Store, which caters to iOS users, and Google Play, belonging to the eponymous company, which is the official app store for the Android OS.

The fact that mobile apps are relatively easier to create than computer apps, and are considerably lower in price, has translated into a growing industry, which every year produces more and more. In fact, it is impossible to know exactly how many apps there are, but as of March 2018 there were some 3.6 million apps in Google Play alone, 100 thousand more than in December of the preceding year. The Apple Store, on the other hand, went from 800 apps the month of its launch in July 2008 to 2.2 million in January 2017. Apple estimated that by September 2016, apps from the Apple App Store were downloaded a cumulative 140 billion times.
