App stickiness refers to the ability of a mobile app to keep users engaged and using the app over an extended period of time. A sticky app is one that provides a valuable and enjoyable user experience that keeps users coming back. There are many factors that contribute to app stickiness, including ease of use, useful features, personalised content, and push notifications. An app’s stickiness can also mean high retention rates, with users returning to the app multiple times during a specific time. For app developers, improving stickiness is a key goal, as it can lead to increased user acquisition, higher customer lifetime value, and better overall app performance.
