App Store Numbers
David Smith, App Store Longevity and Freshness:
It is, however, a bit staggering to think that these numbers mean that there are around 300,000 apps on the Store currently that have seen an update in the past 3 months. It took over 2 years for the App Store to even reach 300k apps listed. That speaks to me of a very wide developer community clamoring for attention in the App Store.
The percentage of apps that don’t get updates may be smaller than you think. Later in the article David Smith puts the percentage of effectively-abandoned apps at 40%, which is a smaller number than I would have expected. (I would have guessed 60%.)
