The App Store shrank for the first time in 2017, according to a new report from Appfigures. The report found the App Store lost 5 percent of its total apps over the course of the year, dropping from 2.2 million published iOS apps in the beginning of the year, to 2.1 million by year-end. Google Play, meanwhile, grew in 2017 – it was up 30% to more than 3.6 million apps. Appfigures speculated the changes had to do with a combination of factors, including stricter enforcement of Apple’s review guidelines, along with a technical change requiring app developers to update their apps to the 64-bit architecture. Apple had also promised back in 2016 that it would clean up its iOS App Store by removing outdated, abandoned apps, including those that no longer met current guidelines or didn’t function as intended.
