Learn to implement user-focused performance tracking strategies for React Native applications in this 14-minute conference talk from React Universe Meetup SF. Discover why traditional performance metrics like FPS don't reflect actual user experience and explore Expensify's approach to measuring only what impacts users. Master the art of defining UX-focused metrics that provide meaningful insights, understand which KPIs Expensify tracks weekly and their rationale, and explore how they leverage StatsD and Grafana to identify performance regressions. Examine why error page counts and skeleton load durations serve as critical performance indicators, and learn how remote caching through React Native Everything Framework (RNEF) enables 90% faster deployment of performance fixes. Gain practical insights into building a performance tracking system that prioritizes user experience over vanity metrics, helping you focus engineering efforts on improvements that truly matter to your users.
