Google Play Console: the meaning of "Active Users"
The 'Active Users' on Google Play Console is defined as: "The number of users who have your app installed on at least one device that was active in the preceding 30 days".
Is the phrase "that was active" refer to the app usage or just the device activity?
In other word, can I use this metric to measure if the users are using/opening my app? or it is just an indication on how many active devices have my app installed but not necessarily using it.
If this definition doesn't help in indicating how many time the app was used, how can I measure that?
Below is a screenshot of the Active User reporting UI, where we can find the definition of "Active Users":
It means how many active devices have your app installed but not necessarily using it. If you want to find out how many people are using it daily, you have to implement analytics. Here is a guide on how to do it: https://developers.google.com/analytics/devguides/collection/android/v4/
