The number of users in your product on a specific day. Often used alongside WAU (Weekly active users) and MAU (Monthly active users) to determine product improvement over time.

More context on Daily Active Users

Daily Active Users (DAU) is a metric that measures the number of unique users who engage with a product or service at least once a day. For B2B SaaS companies with free trials or a free offering, tracking DAU is important because it provides insights into the daily engagement of their users.

For example, a customer relationship management (CRM) software would track their DAUs to understand how many users are using the platform as a part of their daily workflow.

Facebook's DAU in 2021 was reported to be around 1.8 billion users, showing that the platform had a high level of engagement from its users. Similarly, gaming apps like Candy Crush and PUBG have a high DAU as they are played by millions of users worldwide every day. While not every SaaS company should have the rate of DAU that Facebook and games do, users should likely be logging in at least once a week (WAU).
