How big is the mobile app market really?
It is quite certain that the mobile app market is huge, so huge that it is worth tens of billions. It is even estimated that by 2016, the app market will be worth about $70-100 billion. The highest revenue is from in-app purchases and ads. It is a very profitable industry, but it doesn’t mean that there isn’t much competition. As of the first quarter of 2015, there are about 1.3 million apps in the Play Store, 1.2 million in the App Store, 300,000 in the Windows Phone Store and 240,000 in the Amazon Appstore. Three hundred thousand of these apps are from the gaming category alone.
