Source: M:Metrics. Reports for the month of April are projected to represent the universe of smartphone owners and are based on in-tab panel sizes of approximately 500 panelists in the United States and 600 panelists in the United Kingdom.

The data above is derived from M:Metrics' proprietary panel of metered smartphone device owners, selected to represent a population which accounts for a highly disproportionate share of mobile data services usage. Smartphone users browse the Web, download applications and consume multimedia programming such as music and video at up to six times the rate of owners of other handsets.

The patent-pending M:Meter continuously and unobtrusively monitors messaging, browsing, application and media usage and powers M:Metrics' MeterDirect Syndicated Measurement Service.

Smartphone usage is driving the emerging mobile Web and this will be one of the keys to advertising-based business models. According to M:Metrics data, more than one-third of smartphone browsers are using the Web almost every day and on average. Smartphone owners drive a disproportionate share of revenue for mobile operators and content providers and understanding their behavior is a key to understanding how to best monetize the mobile medium.
