Amazon, the Seattle-based online retailer, launched its free App Analytics SDK in November 2013 to allow developers that publish apps for iOS, Android, and its own Fire OS to track various metrics about user retention and engagement.
Amazon’s analytics suite comprises two sets of functionality:
Analytics. Once integrated, the Amazon analytics SDK tracks data about users’ interaction with an app and reports usage statistics through its dashboard. Amazon reports the following metrics:
- DAD (“Daily Active Devices”, or DAU), MAD (“Monthly Active Devices”, or MAU), “sticky factor”
- Total sessions, Sessions per DAD
- Day 1, 3, and 7 Retention and Week 1, 2, and 3 Retention
- ARPD (“Average Revenue per Device”, or ARPDAU), ARPPD (“Average Revenue per Paying Device”, or ARPPU)
A/B Testing. The Amazon analytics SDK also allows developers to A/B test in-app features and control those tests from its web-based dashboard.
