How to Use This Tool
Average DAU divided by monthly active users gives a simple stickiness ratio. Keep the app, identity definition and calendar window consistent.
Why App DAU/MAU needs more than a raw total
DAU and MAU must use the same identity and activity definition; mixing devices with accounts invalidates the ratio. Use the ratio to compare recurring daily activity against monthly reach. It is an engagement metric, not a retention rate or a stand-alone product quality score.
The exact App DAU/MAU formula
DAU/MAU stickiness equals average daily active users divided by monthly unique active users × 100. The visible fields are Average daily active users and Monthly active users. Match the app, identity definition and calendar window. Average DAU should not exceed monthly unique users when both measures use a consistent definition.
Interpreting dau/mau stickiness
Compare the same app, identity definition and calendar window; do not treat this ratio as retention. The ten-percent comparison is deliberately narrow: it tests the influence of daily active users and is neither a forecast nor a confidence interval. Preserve the values used, their dates and the resulting decision so a later reviewer can reproduce why App DAU/MAU supported the choice.
What this App DAU/MAU model leaves out
The ratio is not retention, does not reveal visit frequency distribution and can be distorted by seasonality. DAU must remain less than or equal to MAU under the same definition. That is where App DAU/MAU stops being trustworthy. If an excluded factor could reverse dau/mau stickiness, extend the model explicitly or use the authoritative account system instead of hiding the factor inside an unexplained adjustment.
Evidence and independent verification
The reference reviewed for App DAU/MAU is Apple Developer — App Store Connect Analytics. Apple Developer — App Store Connect Analytics supports the named definition or rule but does not supply private values for dau/mau stickiness. Before acting on the result, reconcile the worked example with the relevant dashboard, invoice, export or measurement.
Private, reproducible calculation
App DAU/MAU runs its arithmetic in the current browser tab and requests no login or API key. That keeps the App DAU/MAU inputs away from the site's calculation server, while leaving the user responsible for detecting stale data or a changed platform rule. When an assumption changes, reopen Apple Developer — App Store Connect Analytics and rerun the saved App DAU/MAU scenario.
