The number of app launches per day is a key performance indicator (KPI) that measures the number of times a mobile app is launched (or opened) by users on a given day. This metric can be useful for tracking the engagement and usage patterns of your app’s users.

To calculate the number of app launches per day, you will need to track the number of times that the app is launched by users on a daily basis. This can typically be done through analytics tools or through in-app tracking mechanisms.

Tracking the number of app launches per day can provide valuable insights into how often your app’s users are interacting with your app, and can help you understand how well your app is retaining and engaging users over time. By comparing the number of app launches per day to other metrics, such as average session length or time spent in app, you can get a more complete picture of your app’s usage patterns.
