Daily Active Users (DAU)

Daily active users (DAU) is a metric that measures the total number of users that log in and engage with your product daily. An “active user” refers to one unique user logging in.

What are Daily Active Users?

The daily active users of your app are all the people who use it in a day or within a given time. Firms that develop applications for frequent use, including gaming apps, regularly check this metric. An active app user has installed or downloaded the app and also uses it actively. Still, the interpretation of an active interaction may change from one business or industry to another.

More personal information about users is used to identify them through PUID IDFA, email, user ID, cookies, or similar approaches if the others do not work. An action in an online banking app could be explained as a transfer, while for an e-commerce app, it may be a person putting items in a shopping cart. The use of the software and the way it operates are considered the main measures of activity in a SaaS business.

How to Calculate Daily Active Users (DAU)

At first, DAU appears to be very easy, but the main problem is figuring out what we mean by an ‘activity.’ To help you manage this process, try to go step by step:

1. Set Your Definition of an Active User

Make sure you’ve defined what would be an action taken by the user within the system. This might be as easy as pushing a button or more precisely, scrolling your app.

2. Determine the Frequency of Engagement

Daily user engagement is what we need to look at in this case, so you should review how many users engage on a daily basis.

3. Collect and Analyze the Data

With the click of a button, check the activity of all users who were active during that day and include only the unique ones to find the number of users involved in that interest.

Let’s put this into perspective with an example:

  • Active User Definition: A user who performs certain actions – clicks, swipes, or scrolls.
  • Frequency: Daily (Daily Active Users).

Here’s what happens on a given day:

  • User 1 clicks a button, closes the app, then logs back in to the app and clicks it again.
  • User 2 opens the app and does nothing more to it.
  • User 3 enters and interacts – they scroll, swipe, or click a button.


The Result:

Our daily active users (DAU) count for the day is 2. Here’s why:

  • User 1 is treated as an active user (although it has been listed only once), but if they have multiple actions, they will be recorded only once.
  • User 2 does not qualify as ‘active’, therefore, is not included in the numbers.
  • User 3 falls under the category of active user, hence is considered.

The way you define your daily active users (DAU) will change based on your company’s targets and the kind of app you are constructing. The way forward for one company could be based on something totally different than what would work for another and this is okay. Create your definition of active users according to your beliefs about growth and being successful.

Why Should You Use It?

The value of DAU cannot be minimized since it accurately mirrors the condition of your app or product’s health. Here’s why tracking DAU can make a big difference:

  • Engagement Indicator: DAU demonstrates how useful and liked your app is by reflecting how often users come back. If many users interact with your app every day, this is a sign of a healthy app, but low DAU suggests there might be problems.
  • Identifies Trends: Tracking DAU helps you notice trends related to adding a feature or seeing changes in how users interact, so you can make better choices.
  • App Stickiness: DAU allows you to see if your app is able to keep users engaged over the long run. Together, MAU and DAU give an idea of how often users keep using the app.
  • Guides Strategy: DAU defines product and marketing plans and helps boost user experience, bring more engagement, and increase your earnings.
  • Business Health: The DAU metric helps you assess how much your app can develop and attracts investors by measuring its activity, making it very important for your business’s performance.

How DAU (Daily Active Users) Relates to Other Metrics

DAU vs. MAU: Comparing (DAU) daily active users with (MAU) monthly active users allows you to see how regularly your app is being used by users during a whole month.

Stickiness Ratio: User loyalty and retention are indicated by the ‘DAU/MAU’ ratio, which is also called the stickiness ratio. If ratio is higher, it means users are using the app more often.

Churn Rate: With DAU, it becomes possible to identify users who stop using the service. An obvious sign of user disengagement is when DAU declines, which helps you handle retention problems right away.

Challenges in Measuring DAU

  • Defining “Active” Users: Because every app has a different goal, defining an active user is not easy and can vary a lot.
  • User Behavior Variations: Different user behaviors (e.g., passive vs. active users) can skew (DAU) daily active users numbers if not accounted for properly.
  • Data Accuracy: Verifying that all data about users is correct, mainly for those who use smartphones and other devices or various platforms to prevent counting people twice or less than they actually should.

Limitations of DAU

  1. Limited View of Engagement: DAU misses information on long-term engagement and different levels of interaction a user could have.
  2. Skewed by Irregular User Patterns: (DAU) daily active users may not give an accurate picture when users use the app irregularly and in short periods.
  3. Overlooks Passive Users: It doesn’t include people who don’t use certain features but are still useful to the platform (for example, those who look at content or check notifications).
  4. Varying Definitions of “Active”: How “active” is defined can change, which can result in wrong user-count totals if the criteria is not well chosen.
  5. Short-Term Fluctuations: Because (DAU) daily active users can vary day by day, it is hard to catch general trends in users’ activity.
  6. Doesn’t Identify Churn: Because DAU lacks drop-off details, it is tough to address issues with user retention without using other metrics.
  7. Lack of Context: It is not enough to use DAU; app’s performance can be seen in better context when you also consider MAU or retention rates.

The DAU/MAU Ratio

Once you calculate MAU, the DAU/MAU ratio can point out how much of your monthly active users log in and open your app daily.

With this metric, you can predict the upcoming success and possible income, and also find out how important your product is by observing the number of users who come back. Strong user retention and real value to your app’s users are highlighted by a DAU/MAU ratio that is higher than average.

This is how the calculation is done:

daily active users ratio



If you consider August, your app was used by 3,500 DAUs and 12,000 MAUs. Therefore, your stickiness ratio for the month is 29% for the month.

Being in this position is the right choice. Twenty percent is considered decent, but anything higher than 25% is really outstanding for this ratio. A 29% ratio indicates that your app has good engagement, so users revisit it very often.

How to Increase DAU?

You can increase your Daily Active Users (DAU) by coming up with methods that get them involved and invite them to use your app on a daily basis.

  • Deep linking: With deep linking, you can direct people to particular features inside your app, which makes it simpler and quicker for them to get involved. Deep links can guide users to your app through emails, SMS, or any other marketing approach.
  • Email and SMS: Email and SMS campaigns help increase acquisition as well. Reminding people about your app through emails or SMS may encourage them to come back and use it. Special messages that are aimed at specific customers will catch their eyes and inspire faster action.
  • In-app messages: Engaging users is possible through using in-app messages. Providing timely and relevant material or rewards when users are within the app will help them continue using the app. No matter if there is a new feature to find out or a task to complete, in-app messages give users reminders without interrupting what they are doing.
  • Push notifications: Push notifications can help let users of your app know they haven’t been using it lately. Updates or information about unique promotions delivered through notifications prompt users to access the app regularly. We must keep our notifications controlled so that users do not decide to quit using the app.
  • User engagement campaigns For example, if a business launches challenges, loyalty programs, or promotions, users will be motivated to take part again and again. Because of these campaigns, users are more likely to come back often to collect prizes or stay informed about new things happening.
  • Creating a sense of community within your app can help drive DAU. Features like forums, social sharing, or user-generated content allow users to interact with each other, building loyalty and engagement. When users feel like they belong to a community, they are more likely to return daily.

Conclusion

You can increase (DAU) daily active users by developing methods of getting our users to come back daily. In case users are still active on the app, they will log-in every day. It is significant to make DAU use regularly so that the numbers can continue growing. 

One of the ways to make them feel they belong is to use personalized information based on the activity of each user. This involves valuable messages and updates posted to the app. The app gets updated with new features, which make it interesting and the users tend to explore the new features quite frequently.

The incorporation of daily missions or collectable points or special content can encourage the user to open the app every day. The content and social tools made up by users can motivate people to be loyal and continue to be engaged. Due to these measures, the users stay united with the platform and continue to visit it.
