Session Length
Session length measures the average time users spend in your app per session. Longer sessions generally indicate higher engagement and can positively influence app store rankings.
Session length reflects how engaged users are once they open your app. While the optimal session length varies by app category (games vs. utilities), consistently longer sessions indicate a valuable user experience.
App stores use engagement signals including session length to assess app quality. Apps that keep users engaged tend to receive better placement in recommendations and search results.
