The company is quick to point out that not all of those apps are active (downloadable), with the total number of active applications sitting at around 80%. Of the combined number of apps published to either the App Store or Android Market, iOS accounts for 52% (roughly 520,000 apps) of the million titles published, whether they are active or inactive.
AppsFire tracks each app entering either the App Store or Android Market, using algorithms and friend recommendations to suggest apps that smartphone owners might be interested in.
The company looks forward to tracking 1 million live apps combined on iOS and Android, then 1 million apps by operating system. via blog.appsfire
