Apple's giant selection of App Store apps was first signed in 2017, according to a report from the Reporting Platform Appfigures lost 5 percent of its total app count over the year to the online storefront.
Appfigures cited statistics from millions of app entries for iOS and Android 2.2 million at the beginning of 2017 to 2.1 million at the end of the year.
By comparison, the total number of Android apps on the Google Play Store grew to 3.6 million over the same period, an increase of 30 percent over the previous year. The App Store and Google Play have been on similar tracks since 2014, but that changed in 2017.
The results were highlighted on Wednesday by TechCrunch .
The reason for the noticeable drop in App Store numbers is unknown, but Appfigures speculates on a stricter enforcement of Apple's review policy and the abolition of iOS 11 support for 32-bit apps contributed to the decline.
At the end of 2016, Apple also began removing obsolete and "problematic" apps from its store, a process that could potentially have reached 2017. The culling was part of the Apple plan to only market "quality apps" to customers.
It seems that we are in favor of tighter control of the App Store, leading to a 29% drop in app launches. In 2017, iOS developers released 755,000 apps. This was the first decline since the launch of the Appstore in 2008. In contrast, the Google Play Store released 1.5 million Android titles, an increase of 17 percent over the previous year.
In addition to a decline in published apps, the report suggests that more developers port iOS devices to Android than vice versa. The developers translated almost 17,500 iOS apps to Android in 2017, while only 7,500 switched from Android to iOS. There are currently approximately 450,000 apps available on both the App Store and Google Play, about 8.5 percent of the total.
The remainder of the report includes details on app development tools, country deliveries, developer growth in China, and a breakdown of key app categories. Games are expected to be launched on both the App Store and Google Play.
