An uninstall is the process of completely removing an application from a mobile device. Every uninstall is a churned customer, and contributes to your churn rate.
Tracking uninstalls is part of the process of mobile marketing. The number of uninstalls serves as a gauge of the health of your app.
The sooner you learn when and why users are uninstalling, the faster you can get them back using a winback campaign. Find out immediately when a user uninstalls and send targeted campaigns to increase engagement and thus reduce churn.
