App downloads
The number of app downloads is the initial indicator of interest and visibility. High download figures suggest strong marketing, appealing app store listing optimization (ASO), and effective promotion. However, downloads alone don’t guarantee active use; they serve as the starting point in the engagement funnel.
While not all downloaded apps are used regularly, tracking download trends helps you understand the effectiveness of your acquisition strategies. From there, analyzing subsequent behaviors such as active sessions and retention rates paints a clearer picture of your app’s actual popularity and stickiness.
Daily Active Users (DAU) and Monthly Active Users (MAU)
Daily Active Users (DAU) reflect the number of unique users engaging with your application each day, while Monthly Active Users (MAU) measure engagement over a longer period. The ratio of DAU to MAU reveals how often users return, indicating the level of app “stickiness” and habitual use.
A high DAU/MAU ratio suggests your app provides consistent value, fostering regular interaction. Monitoring these metrics over time helps identify trends, seasonal effects, and the impact of new features or updates on user engagement.
Session length and session interval
Session length measures how long a user stays active during a single interaction, providing insights into content engagement and app usability. Longer sessions often indicate a compelling user experience.
Session interval tracks the time between consecutive app visits. Shorter intervals imply users find your app valuable enough to revisit frequently, reinforcing engagement and user loyalty.
Retention rate
Retention rate is the percentage of users who return to your app after their initial visit within a specified timeframe. High retention signifies that users find your app useful and engaging, which is essential for long-term success. Focusing on improving retention can lead to increased lifetime value and reduced dependency on constant new user acquisition.
Mobile app performance metrics
Technical metrics are the backbone of app performance evaluation, directly impacting user experience and device resource management.
Load time
Load time is the duration from app launch to full readiness for interaction. Ideally, this should be under two seconds; longer load times tend to increase bounce rates and frustrate users. Optimizing startup processes, minimizing initial data loads, and preloading essential resources can significantly improve load times.
Crash rate
The crash rate indicates the stability of your app by measuring the percentage of sessions that terminate unexpectedly. Keeping this below 1% is generally considered acceptable, as frequent crashes damage user trust and lead to negative reviews.
API latency
API response time influences how quickly your app fetches data from servers. Lower latency results in a more responsive experience, with response times ideally under one second. Efficient backend infrastructure and optimized network requests are key to minimizing delays.
