November set App Store's 'highest monthly sales ever,' says Apple's Schiller

Phil Schiller made the boast on Twitter without providing any specifics, such as whether he meant downloads or — presumably — revenue for both Apple and developers.

While App Store sales can fluctuate from month to month, they have generally been on an upward trend since 2008 alongside a growing number of iPhone and iPad owners. That in turn has attracted high-profile developers, a number of which have figured out how to further monetize their work via in-app purchases.

Sales are likely to run even higher this month, since iPhones and iPads can be popular Christmas gifts, and new owners tend to binge on apps to make them useful. During the last holiday season, over $1.1 billion was spent at the App Store between Dec. 20 and Jan. 3.
