Daily Active Users (DAU)
DAU counts the number of unique users who perform at least one meaningful action in your product on a given day. "Meaningful" is key — most teams exclude passive opens and count only actions that signal genuine engagement (a message sent, a document edited, a search run).
Note: Define "qualifying action" explicitly before measuring. Logging in is usually not enough.
DAU/MAU ratio > 20% is solid; > 50% is exceptional (WhatsApp, Slack in active teams)
DAU/MAU < 10% suggests most users are not finding regular value
Benchmarks by segment
How to improve DAU
Identify the "aha moment" — the action that correlates most strongly with long-term retention — and optimise onboarding to reach it faster
Introduce daily habits: digests, reminders, or streaks that give users a reason to return each day
Reduce friction in the most common returning-user flow — every extra tap reduces DAU
Segment DAU by cohort to identify which acquisition channels bring the most engaged users

Frequently Asked Questions
Use the interval that matches your product's natural usage cadence. Daily collaboration tools (Slack, Notion) suit DAU. Weekly planning tools (roadmapping, OKR software) suit WAU. Using the wrong interval makes engagement look worse than it is.
Reverse from your business goal. If you need $X ARR and your conversion rate is Y%, you need Z MAU. Multiply by your target DAU/MAU ratio to get your DAU target. Don't set DAU targets in isolation.
