In addition to its new report on the top apps of 2019, app store intelligence firm App Annie also closed out the year with its Decade in Review analysis, which looks at the most popular apps over the past 10 years. Not surprisingly, Facebook dominated the charts, claiming four of the most-downloaded apps of the decade with Facebook, Messenger, WhatsApp and Instagram. Subway Surfers, meanwhile, became the most-downloaded game of the decade, thanks to strong adoption in India.

To be clear, the analysis excludes third-party app stores in China, instead relying on iOS and Google Play data to come up with the list of top apps. But this still provides a way of examining worldwide app trends, despite that exception.
