A session is a period of time where a user interacts with an app. Session time is a primary measure for user engagement as it records the length and frequency of end-user.

Similarweb slices sessions metrics in several ways:

  • Sessions Per User: The average number of sessions for a user in a day. 

  • Avg Session Time: The average session length for a user in a day.

  • Total Session time: The average total session time a user spends in the app in a day.


At Similarweb, a session is triggered by the opening of an app. A session ends when a user closes the app or moves to another app.

Sessions Per User = Total number of Sessions / Number of active users (calculated daily)  

Avg Session Time = Total session time / number of sessions (calculated daily) 

Total Session time = Total session time / Number of active users (calculated daily)

Using these metrics

These metrics help our customers answer the critical questions needed to build a highly successful engagement strategy.

By combining analysis of session metadata (e.g., avg sessions time) and then analyzing behavior across a user base, app businesses can identify opportunities or problems within their apps that can be optimized for improved user retention and user engagement.
