Most game companies manage their businesses using operating metrics that give insights into audience (metrics such as Daily Active Users, or DAU; Monthly Active Users, or MAU; number of installs; various day retention); and monetization (metrics such as Average Revenue Per Daily Active User, or ARPDAU, number of Payers, Average Revenue per Paying User or ARPPU).
The key objective of these operating metrics is to help managers understand the fundamental health of the games and their future outlook, and to help make business decisions.
