The goal of the Overview page is to provide you with the key metrics about your app users. This includes their devices, location, activity, and engagement. This allows you to answer questions such as:

  • What are the main devices being used?
  • Can I remove support for an old OS version?
  • Should I translate my app into a new language?
  • Are my users adopting my latest version?

All the data in the Overview page can be filtered by time range and app version, so you can further drill down into your charts. The app version needs to follow the Semver 2.0 format.

Active users

Represents the number of unique app installations that launched the app in the last:

  • 1 calendar day for the "daily"
  • 7 calendar days for the "weekly"
  • 28 calendar days for the "monthly"

A new day starts at 12am UTC.


Engagement measures the daily sessions per user and session duration.

A session is defined as the time from the app coming to foreground to the last event before going to the background. If no custom events are identified within 5 minutes in a session, the session won't be counted.

Analytics will offer you the following information:

  • Daily sessions per user: Daily average number of sessions per user.
  • Total sessions: Total number of sessions.
  • Average sessions per day: Number of sessions per day averaged over the time range.
  • Session duration: Distribution of the number of sessions over a few duration intervals.
  • Average session length: Average of all the session durations in the selected time range.

Devices and OS

The Devices panel gives information about the users' devices:

  • Device model distribution: Shows the count and percentage of the top most used device models.
  • OS distribution: Shows the relative percentage of the top most used OS versions.

Active Users per Version

The Active Users per Version panel shows how many users are using a given version. It will show the latest 20 versions only.

Countries and Languages

The Countries and Languages panel displays information about devices geographical location and language settings in the device.

The country/region is determined by the carrier country/region and requires the device to have a SIM card. If you're using a simulator or another device with no SIM card such as a tablet, the country/region will be "unknown" or inaccurate.

The language is the one defined at the OS level by the user.
