Use the App Performance Score to calculate your overall performance score and discover opportunities for improvement. The App Performance Score provides a standardized framework to measure performance with minimal in-depth technical tasks.

It guides engineering and product teams to assess technical performance of any given Android app. After the assessment is complete, an evaluation and recommended actions help to identify and prioritize the most important areas for performance improvement.
| **Preview:**This page contains the first iteration of the App Performance Score.
|
| - Scoring, evaluation and recommendations are likely to change in the future.
| - Recommendations and guidance provided has curated with performance impact in mind.
| - Tools and guidance in the recommendations are stable and can help to improve app startup and rendering performance.

### Introduction

The App Performance Score provides app developers with static and dynamic assessments. Both can be conducted individually and provide unique insights into an app's performance behavior. These insights are coupled with actionable recommendations which can help to improve the status quo and elevate the app's performance.

A score between 0 and 100 is provided to help gauge the overall performance. A lower number means more room to improve.

Use the score and recommendations for each item to direct engineering efforts into areas where high performance gains can be achieved. When recommendations have been applied, take the assessment again and see how the score has improved.

| The application's runtime behavior is used to assess performance characteristics. The dynamic performance score is a direct reflection of how well an app performs on a specific device. | The application is statically assessed to evaluate performance predictors based on use of best practices and tooling adoption. The static performance score highlights tools with high impact on app performance. No runtime evaluation is needed for this score. |

## Dynamic App Performance Score

During dynamic assessment of the App Performance Score, runtime data are used to evaluate an app's performance on a specific device.

The dynamic assessment requires a physical device for a realistic performance evaluation. The score will vary depending on the device's capabilities. Assess the performance on multiple devices to get a better understanding how users are impacted by performance shortcomings.
| **Tip:** Use lower end devices to exaggerate performance issues. This will result in an overall lower score and emphasize areas that can be improved.

The current dynamic app score categories and assessment criteria are outlined in the following table.

|       Category        |                                                                     Assessment criteria                                                                     |

| Application startup   | Measured duration between app startup and the app becoming interactive[TTFD](https://developer.android.com/topic/performance/vitals/launch-time#time-full). |
| Rendering performance | Percentage of slow and frozen frames for scrolling, animating and full screen renders.                                                                      |

| **Instructions to measure app startup performance**
|
| - Always test cold startup time.
| - Ensure the app is killed between tests.
| - We recommend one of these methods to calculate performance metrics
|   - Use the[macrobenchmarks](http://developer.android.com/topic/performance//topic/performance/benchmarking/macrobenchmark-overview)for fully automatable and highly accurate results.
|   - Profile app launch time using[system tracing](http://developer.android.com/topic/performance/tracing)for accurate results.
|   - Manual testing will yield imprecise results that should be refined later.
| **Tip:**Repeat the measurement for more accurate results. Kill the app between tests.

Static App Performance Score

(0/7 questions answered)

## Tips for evaluating your app

Here are some tips when measuring your App Performance Score.

### Choose a representative device

When measuring your dynamic score, we recommend using the same type of device as your user base. 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.

### Assess dynamic score variability

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.

Your static score should remain stable unless you change your code.

### Use scores separately if needed

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.

### Supplement with other monitoring metrics

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[Android Vitals](https://play.google.com/console/about/vitals/),[Firebase Performance Monitoring](https://firebase.google.com/docs/perf-mon), and[benchmarks](https://developer.android.com/topic/performance/benchmarking/benchmarking-overview).

## How to improve your score

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.

Within each segment, the App Performance Score provides actionable steps to improve your app.
