App churn rate
What is churn rate? App churn rate is the percentage of users who uninstall or stop engaging with an app over time. App churn can also be used interchangeably with abandonment rate. This app metric is typically measured at 30 days, 7 days, and 1 day after users first install the app. App churn rate is the exact opposite of app retention rate. Whereas app retention rate reveals how loyal a user base is over a period of time, app churn rate shows app developers exactly when in the app lifecycle users begin dropping off.
How to calculate churn
To understand why users churn, app developers can usecohorts, which enables them to leverage user behavioral data to better understand drop off points in their in-app experience, and address them in order to retain app users. Churn rate is calculated by this formula:
Churn rate = 1 - (# of monthly active users / # of monthly installs)
