Daily Active Users (DAU) and Monthly Active Users (MAU) both measure user engagement, but they operate on different time scales and reveal distinct aspects of user behavior. DAU counts unique users who engage with a product within a 24-hour period, providing immediate insights into day-to-day engagement fluctuations and product stickiness. MAU, meanwhile, counts unique users who engage at least once over a 30-day period, offering a broader view of the overall user base and potential reach, regardless of how frequently each user engages.
A mobile gaming company might prioritize DAU when evaluating the impact of new game features or daily rewards, as it shows whether these elements successfully drive habitual daily usage. The same company would turn to MAU to understand their total active player base and market penetration. Using these metrics together—particularly in the form of the "stickiness ratio" (DAU/MAU)—provides even more insight, showing what percentage of the monthly user base engages daily. For instance, a rising MAU with declining DAU might indicate successful user acquisition but poor retention, signaling a need to improve the core product experience rather than increasing marketing spend.
