Having made my claim that ratings are a good indicator of downloads I’m going to look at the top app developers. As of a week or so ago 39,175 developers have at least 1 application on the store. I’ve compiled the Top 100 app developers and included them in a plot below. Check out Inedible Software at #68. There are two things I find interesting about this data:
1) The top app developers are gigantic. Gameloft has just about 2.3% of all ratings, which means they probably have near 2.3% of all downloads. Digital Chocolate is almost as large, with about 2% of all ratings. We ourselves have 0.23%, which from Apple’s stated total number of app downloads is just about spot on.
2) The top 100 app developers have 40% of all ratings! Looking down a bit further, the top 170 control 50%, which means that the bottom 39,105 developers have as many downloads as the top 170. Tough market.
