Churn rate is the percentage of users your product or app loses within a given time frame. Mobile app churn rate is typically measured at either one, seven, or 30 days after installation and is an essential metric for measuring user satisfaction at different points in an app’s lifecycle.
While a certain level of churn is expected for every business, mobile app teams should be doing everything in their power to keep their churn rate as low as possible. Simply put, if your app is to see any sustained growth, you must keep your user retention higher than your user churn.
