Mobile application retention rate refers to the percentage of users who continue to use a mobile application after a certain period of time. It is a measure of the app’s ability to retain its users and keep them engaged. A high retention rate indicates that the app is successful in retaining its users, while a low retention rate may suggest that the app is not meeting the expectations of its users. Factors such as user experience, app updates, and competition can all impact the retention rate of a mobile application. A strong retention rate is crucial for the long-term success and growth of a mobile app.
