FAQs

What is a good DAU/MAU ratio for a SaaS product?

It depends on the intended use frequency. Daily-use tools (Slack, productivity apps, trading platforms): target 40–70% DAU/MAU. Weekly-use tools (project management, analytics): 15–30%. Monthly-use tools (accounting close, payroll): 5–15%. Comparing DAU/MAU to the product's intended use cadence is more meaningful than absolute benchmarks — a tax tool with 10% DAU/MAU during non-filing months isn't a product health concern.

How do you improve DAU without just sending more push notifications?

Sustainable DAU improvement comes from making the product more valuable for daily use: adding features that create daily jobs-to-be-done, building habit loops (triggers, actions, rewards), improving notification relevance and timing (rather than volume), developing collaborative features that create social obligations, and ensuring the core daily use case is faster and more frictionless than alternatives.

What is WAU and when is it preferred over DAU or MAU?

WAU (Weekly Active Users) is used for products with a natural weekly use cadence — project management tools, content creation platforms, or professional tools aligned with the work week. It avoids the volatility of daily measurement (weekends show lower DAU for professional tools) while capturing more signal than monthly. DAU, WAU, and MAU together paint a complete engagement picture across different time horizons.

Daily Active Users (DAU) measures the number of unique users who perform at least one qualifying action in a product on a given day, serving as the most granular indicator of daily engagement and habit formation. It is particularly important for products where daily use is expected — messaging apps, social media, gaming, email — rather than occasional-use tools.

DAU is rarely reported alone but in combination with MAU (Monthly Active Users) as the DAU/MAU ratio, commonly called 'stickiness' or 'engagement rate.' This ratio answers: of all users who used the product this month, what fraction uses it on any given day?

DAU/MAU Ratio = DAU ÷ MAU (typically averaged over the month)

Benchmarks: Facebook achieves ~65% DAU/MAU (exceptional daily habit); Snapchat ~40%+; Twitter ~20%; many professional tools 15–25%; occasional-use apps (travel, tax) 2–5%. Products aiming to be 'daily habits' target 50%+ DAU/MAU.

DAU growth and DAU/MAU trends are leading indicators of product health for consumer apps. Declining DAU while MAU is stable suggests monthly users are using the product less frequently — an early warning of engagement erosion that typically precedes churn. Conversely, rising DAU from a stable MAU base indicates users are forming stronger habits.

For B2B SaaS tools used daily by professionals (Slack, Notion, Figma, linear), high DAU relative to seat count validates product-market fit — users are integrating the tool into their daily workflow. For business intelligence or reporting tools used weekly or monthly by intent, targeting high DAU/MAU is less appropriate.

Real-time DAU dashboards are standard infrastructure for consumer tech teams, enabling rapid response to engagement changes caused by product releases, outages, or competitive events.
