Unlike the static score, a dynamic score will vary based on the device specs. If you don't know where to start, use a low-end device and work on improvements from there.</p> <h3 id="assess_dynamic_score_variability" data-text="Assess dynamic score variability" tabindex="-1">Assess dynamic score variability</h3> <p>It's possible that your dynamic score changes across multiple observation periods, without you changing your code. This could be due to inherent variability in the app performance or other system activities happening on your device. If you notice that your score is highly variable, we recommend testing multiple times in sequence and noting the most common behavior.</p> <p>Your static score should remain stable unless you change your code.</p> <h3 id="use_scores_separately_if_needed" data-text="Use scores separately if needed" tabindex="-1">Use scores separately if needed</h3> <p>If you don't have the time or capacity to calculate both the dynamic and static score, you can use each alone as well. Any improvement to your dynamic or static score will still benefit your users.</p> <h3 id="supplement_with_other_monitoring_metrics" data-text="Supplement with other monitoring metrics" tabindex="-1">Supplement with other monitoring metrics</h3> <p>The App Performance Score is a quick, high-level way to assess app performance. To get more detailed performance insights, consider exploring other data sources such as <a href="https://play.google.com/console/about/vitals/">Android Vitals</a>, <a href="https://firebase.google.com/docs/perf-mon">Firebase Performance Monitoring</a>, and <a href="/topic/performance/benchmarking/benchmarking-overview">benchmarks</a>.</p> <h2 id="how_to_improve_your_score" data-text="How to improve your score" tabindex="-1">How to improve your score</h2> <p>In general, if both your static and dynamic scores are subpar we recommend taking actions to maximize your static score before troubleshooting the dynamic one. Addressing shortcomings in the static score will likely improve the dynamic score as well, so it's helpful to optimize the former as a first step to improving your app performance. The static score is based on concrete values or settings in your app code, whereas the dynamic metrics usually take longer to investigate and identify the root cause of.</p> <p>Within each segment, the App Performance Score provides actionable steps to improve your app.</p> <h2 id="recommended_for_you" data-text="Recommended for you" tabindex="-1">Recommended for you</h2> <ul> <li>Note: link text is displayed when JavaScript is off</li> <li><a href="/topic/performance/benchmarking/macrobenchmark-metrics">Capture Macrobenchmark metrics</a></li> <li><a href="/topic/performance/baselineprofiles/overview">Get started with Baseline Profiles</a></li> <li><a href="/topic/performance/baselineprofiles/dex-layout-optimizations">Create Startup Profiles</a></li> <li><a href="/topic/performance/measuring-performance">Overview of measuring app performance</a></li> <li><a href="/topic/performance/vitals/frozen">Frozen frames</a></li> </ul> </devsite-recommendations> <devsite-hats-survey class="nocontent" hats-id="VxqvKSur40kxBYCLVTd0SSGykbno" listnr-id="5207477"></devsite-hats-survey> </div> <devsite-recommendations display="in-page" hidden yield> </devsite-recommendations> <devsite-thumb-rating position="footer"> </devsite-thumb-rating> <devsite-recommendations id="recommendations-link" yield></devsite-recommendations> <div class="devsite-floating-action-buttons"> </div> </article> <devsite-content-footer class="nocontent"> <p>Content and code samples on this page are subject to the licenses described in the <a href="/license">Content License</a>.
