Thanks for sharing that! Check this out:

This table breaks down the paid app developers by total gross. The left column is number of digits in total gross, so 7 means the developer made millions, and 3 means the developer made hundreds.

The right column is number of paid developers in the bucket.

The biggest group is 3, those who made $100 to $999.

Is this analysis valid? Or is this there a missing factor, like old apps not showing up in the store?

Interesting stats, and thanks for sharing! Now, what conclusions can we take from them?

One that stands out is that people are willing to pay for Arcade/Action and Personalization apps beyond what the download distribution would suggest.

I'm interested in knowing what the Pareto distribution is, are there apps that are skewing categories? (eg: a very popular personalization app?).

Also, knowing that paid apps are less than 1% (0.7%?) of all downloads is interesting.

I'm working on gathering more stats; if you'd like you can help out by taking the data available [1] and play with it, as unfortunately these days I'm really busy and this article has already shaved several hours of work ... maybe over the weekend I'll publish more findings.

Thanks! I'm pretty busy myself, but I might take a look over the weekend :)
