Flurry has a new version 3.0 of its free Analytics tool that focuses on audience segmentation, giving mobile application makers the power to segment their audience on any usage behavior (e.g., paying vs. non-paying customers, light vs. heavy users, etc.). They also estimate demographic data such as age and gender for any application using their service. Mechanisms have also been added to this version to allow you to test how long viewers stay in your app. The company says its analytics tools are now in apps reaching 300 million monthly unique users, tracking six billion transactions a day.
