Which mobile platforms does this skill support?

This skill provides implementation patterns and measurement points for iOS (using os_signpost), Android (using Activity/Fragment hooks), and React Native (using React Navigation).

Can this skill help debug slow deep links?

Yes, it specifically includes triggers and patterns for measuring the time from a deep link event to the target screen being fully ready for the user.

What is Navigation Latency in mobile apps?

Navigation Latency is the total time elapsed from the moment a user taps a navigation element (like a button or tab) until the destination screen is fully rendered and interactive.

How does this differ from simple view-appear metrics?

Unlike simple view-appear metrics, Navigation Latency includes the data loading phase, ensuring the measurement reflects when the user can actually interact with the content.

What are the recommended performance thresholds?

Ideally, navigation should complete in under 400ms for a 'Good' rating. Transitions taking longer than 1 second are generally considered 'Poor' and should be optimized.

Mobile Development

Measures and optimizes mobile application screen transition times from initial user tap to a fully interactive state.

关于

The Navigation Latency skill empowers developers to monitor and improve the perceived performance of mobile applications by tracking Time to Interactive (TTI) during screen transitions. It provides structured guidance for measuring the complete navigation lifecycle—from the source tap through view initialization and data loading—to the final interactive state. By implementing specific thresholds and platform-native measurement points for iOS, Android, and React Native, this skill helps identify performance bottlenecks in deep links, tab switches, and list-to-detail transitions to ensure a fluid user experience.
