Stickiness in a product refers to how frequently users return and engage with it over time. A common metric for measuring stickiness is the **[[Daily Active Users (DAU)|DAU]]/[[Monthly Active Users (MAU)|MAU]] ratio** (AVG Daily Active Users / Monthly Active Users). This ratio indicates how often users engage with the product within a given period. A higher percentage suggests stronger habitual usage and user retention. #### Formula for Stickiness: > [!formula] > $\text{Stickiness} = \frac{\text{AVG DAU}}{MAU}$ > > This formula expresses stickiness as a percentage, where *a higher value implies that users engage with the product more frequently*. >[!important]- Theory to create a habitual use > The **Hook Model**, explains how products build habit-forming loops through triggers, actions, variable rewards, and investments. This cycle helps products integrate into users' routines, making them more likely to return repeatedly. > See
