DAU
Daily Active Users
Definition
The number of unique users who engage with a product on any given day, a key metric for measuring app engagement and product health.
Why it matters
DAU tells you how sticky your product is. A high DAU/MAU ratio means users are returning frequently. Investors watch DAU trends as a signal of retention and growth.
Example
A habit-tracking app has 10,000 MAU and 5,000 DAU, a 50% DAU/MAU ratio, indicating strong daily engagement.
