Automating performance auditing for an Expo React Native app involves running a multi-tiered workflow that includes static analysis, bundle composition checks, and on-device measurement. This provides detailed reports on startup time, runtime jank, and memory usage.

A mobile app publishing readiness check validates app metadata, configuration, and permissions for store submission. It also assesses performance benchmarks and checks for security vulnerabilities to ensure compliance with store guidelines before release.

Yes, you can measure startup time and runtime jank using tools like xcrun simctl and flashlight for on-device measurement. The Skill uses these specific tools to capture CPU efficiency and memory usage metrics for React Native apps.

Analyzing bundle composition in a React Native project uses source-map-explorer to inspect the generated bundle. This identifies large dependencies and inefficient imports that impact app startup time and overall runtime performance.

Yes, the mobile performance audit includes a security assessment that checks for security vulnerabilities and best practices compliance. This runs alongside the performance analysis during the static analysis phase.

Automating mobile app performance testing requires access to the app source code and specific local tools like tree-sitter and maestro. It is tailored specifically to Expo React Native apps and cannot audit other mobile frameworks.
