Explore Weekly Active Users (WAU) using your PostHog data
Weekly Active Users (WAU) in PostHog
Weekly Active Users (WAU) measures the number of unique users who engage with your product within a seven-day period, providing crucial insights into user retention and product stickiness. For PostHog users, this metric becomes particularly powerful because PostHog captures rich behavioral data including page views, feature interactions, custom events, and user properties. This comprehensive dataset enables you to understand not just how to calculate weekly active users, but also segment WAU by user cohorts, feature usage patterns, and acquisition channels to inform product development and marketing strategies.
Understanding the weekly active users definition in the context of your PostHog data helps identify which features drive consistent engagement and where users might be dropping off in their weekly usage patterns. This analysis directly informs decisions about feature prioritization, onboarding improvements, and retention campaigns.
However, analyzing WAU manually becomes incredibly painful. Spreadsheets require complex formulas to deduplicate users across rolling seven-day windows, and with multiple user segments and time periods, the permutations become overwhelming and error-prone. PostHog’s built-in reporting, while useful for basic metrics, provides rigid outputs that can’t easily answer follow-up questions like “Which user segments show declining WAU?” or “How does feature X adoption correlate with weekly retention?”
Count eliminates this friction by automatically calculating WAU from your PostHog data while enabling flexible segmentation and deeper analysis.
