The latest count I've seen is 225,000 total apps on the App Store.
So if we divide the 1.43 billion dollars cumulative revenues
earned by those 225,000 apps, we get an average revenue earned
of 6,355 dollars per app (over 2 years).
But you had just said this: Thus free apps would form 85% of all downloaded apps on the
Apple iPhone App Store, and paid apps only for 15% of all apps.
Shouldn't you divide the revenue only by the number of paid apps? That would surely make the platform much more financially interesting.And you are assuming too much averages. How many of the apps got this "average revenue", what how many spent the "average" in development?
