Daily Active User
DAU is the percentage of users who take a particular action within your app. Gauging the success of your mobile app is one of the key aspects of your growth. It’s not the daily users, but the number of regular active users that create value to your business day in and day out. Use this metric to understand how your users experience the app.
To calculate your DAU, divide your total number of daily app sessions with the total number of daily unique users.
DAU = Total # of Daily App Sessions / Total # of Daily Unique Users
For example, if your app has 20000 sessions in a day with 200 unique users, then your daily active users are 100 (20000/200)
