The document discusses sources that mobile app developers can use to gather feedback and usage statistics about their apps. It describes getting active feedback from users through email, website comments, and app store comments, as well as collecting statistical usage data from services like the Android Market, Flurry, and AdMob. Specifically, it outlines the types of usage insights that can be gained from Flurry analytics, such as number of unique users, frequency of use, user locations, device hardware, and specific in-app actions. The document recommends using these data sources to better understand app users and help improve localization, API compatibility, and other aspects of the app experience.
