For independent-owned apps with the 20 million active users, the actual number of apps has only grown from 7 in Q1 2012 to 32 in Q3 2013. In a world where the iTunes App Store now has a million mobile apps to choose from, that’s still a small piece of the pie.

But the number of mobile app developers hitting 1 million is much larger, going from just under 400 to 875 in the same time period.

“These numbers are simply unprecedented, especially because most of these app developers have risen organically, and not as a result of consolidation or through mergers and acquisitions,” writes Flurry CEO Simon Khalaf on the company blog.

In addition, another earlier report from comScore, which Flurry also cites today, found that Facebook and Instagram combined accounted for 26% of all time spent on mobile. Facebook COO Sheryl Sandberg later confirmed comScore’s metrics, saying on a recent earnings call that Facebook accounts for more mobile minutes in the U.S. than YouTube, Pandora, Yahoo, Twitter, Pinterest, Tumblr, AOL, Snapchat and LinkedIn combined.

The takeaway, so far, from reports like these has been that there’s not much room for other mobile apps when so much of users’ time is spent with Facebook, and a few other major app properties. Khalaf says now that’s not so, adding “there appears to be plenty of whitespace for others.”
