The current app store ecosystem doesn’t favor the indie developer. According to new data from Sensor Tower, the top 1% of publishers globally accounted for a whopping 80% of the total 29.6 billion app downloads in the third quarter of 2019. That means just 20%, or 6 billion, downloads are left for the rest of the publishers.

This bottom 99%, which equates to roughly 784,080 publishers, averaged approximately 7,650 downloads each during the quarter. To put that in context, that’s less than one-thousandth of a percent of the downloads Facebook generated in the quarter (682M).
