Time spent in app (also known as session time) is a key performance indicator (KPI) that measures the total amount of time that a user spends using a mobile app over a specific period of time. This metric can be useful for tracking the engagement and usage patterns of your app’s users.

To calculate time spent in app, you will need to track the duration of each user session within your app. You can then sum the total session time for all users over a specific time period (e.g., a day, a week, or a month) to get the total time spent in app.

Here’s the formula for calculating time spent in app:

Time spent in app = Sum of all session times

For example, if your app had 500 sessions with a total of 1000 minutes of session time in a given time period, the time spent in app would be 1000 minutes.

Tracking time spent in app can provide valuable insights into how much time your app’s users are spending using your app, and can help you understand how well your app is retaining and engaging users over time. By comparing time spent in app to other metrics, such as average session length or average daily sessions per user, you can get a more complete picture of your app’s usage patterns.
