According to the cofounder of iOS app discovery tool Appsfire, Apple's iOS App Store has passed the milestone of over one million apps submitted and approved into its marketplace. The store, which opened in July 2008, currently hosts approximately 736,247 apps, 45 percent of which are paid and 16 percent of which are games. The disparity in "live " Apps and the total number of submitted and approved apps is due to some apps' discontinuation, and in some cases because of removal due to violations of Apple's policies.
