Daily Active Users (DAU)
Number of unique users who open an app on a given day.
What Are Daily Active Users?
Daily Active Users (DAU) counts the unique users who open and interact with an app within a single calendar day. Each user is counted once regardless of how many sessions they log. DAU ranks among the most common metrics in the mobile app industry for measuring reach and daily engagement.
DAU in the Context of ASO
DAU plays a significant role in how app stores evaluate popularity and relevance. A rising count signals to store algorithms that an app is gaining traction, which can boost search rankings and category placement. The DAU-to-MAU ratio, often called the stickiness ratio, reveals what percentage of monthly users engage with the app every day. A ratio above 20% is considered healthy for most categories.
Tracking and Interpreting DAU
Monitoring DAU trends over time helps teams gauge the impact of marketing campaigns, feature launches, and seasonal events. A sudden spike may indicate a successful campaign or viral moment, while a steady decline could signal user dissatisfaction or rising competition. Segmenting by acquisition source, geography, or device type reveals which user groups engage most and where growth opportunities exist.
