	att_abstract={{as gateways to Internet services, rather than traditional web
browsers. Application marketplaces for iOS, Android, and
Windows Mobile platforms have made it attractive for developers
to deploy apps and easy for users to discover and
start using many network-enabled apps quickly. For example,
it was recently reported that the iOS AppStore has more
than 350K apps and more than 10 billion downloads. Furthermore,
the appearance of tablets and mobile devices with
other form factors, which also use these marketplaces, has
increased the diversity in apps and their user population.
Despite the increasing importance of apps as gateways to
network services, we have a much sparser understanding
of how, where, and when they are used compared to traditional
web services, particularly at scale. This paper takes
a first step in addressing this knowledge gap by presenting
results on smartphone app usage at a national level using
anonymized network measurements from a tier-1 cellular
carrier in the U.S. We identify traffic from distinct marketplace
apps based on HTTP signatures and present aggregate
results on their spatial and temporal prevalence, locality, and
correlation.}},
