This document discusses the increasing ubiquity of mobile devices and how they can be used to passively collect consumer behavior data through applications. It introduces Survey Analytics' product called LifeMetrix, which integrates with their SurveySwipe app to passively collect opt-in mobile data from respondents on things like GPS, app usage, battery/memory, and more. This new form of behavioral data provides an alternative to traditional surveys that rely on recall by directly measuring actual consumer actions on their devices.
