Quick definition
Active users are the people who engage with a product or platform in a defined period — often measured as daily (DAU) or monthly active users (MAU).
Active users are the count of unique people who take a meaningful action within a product or platform over a set time window, distinguishing genuinely engaged audiences from total sign-ups that may sit dormant. The two most common cuts are daily active users (DAU) and monthly active users (MAU). What counts as "active" is defined by each company — it might mean opening an app, logging in, posting, or completing a core action — so definitions vary and should always be checked before comparing figures across sources.
For platforms and apps, active-user counts are a headline health metric that indicates whether an audience is genuinely using the service rather than just registering once. On the marketing side, the DAU-to-MAU ratio is often used as a rough "stickiness" indicator — how many monthly users show up on a typical day. Social platforms report their own active-user figures to advertisers as evidence of reach, and brands running communities or apps track active users to see whether their content and features keep people coming back.
Active users are most useful when paired with retention and engagement metrics rather than read in isolation — a large user base with a low active share signals a retention problem, not success. Because every product defines "active" differently, the honest practice is to set a clear, consistent definition and track the trend over time rather than chasing a single number. For creators and brands, the equivalent question is not just how many followers you have, but how many actually engage with your content in a given week or month.
