App performance doesn’t improve by accident. You need the right data, the right tools—and the right metrics to track. During this webinar, we break down the five core performance metrics that every React Native team should be monitoring.

Mind you, this session goes beyond theory. You’ll get definitions, real-world examples, and practical measurement methods for each metric, along with tips on how to interpret and act on the data. Whether you’re troubleshooting dropped frames or planning a performance audit, this is the technical insight your team needs.

What you'll learn about performance metrics and why they matter

Poor performance hurts more than user satisfaction Iit affects retention, revenue, and brand trust. Tracking the right metrics can help you spot issues early, prioritize improvements, and make the case for performance work across your team.

Metrics that reveal performance problems before users complain

• What FPS (frames per second) really means for React Native apps, and why 60 isn’t always enough.
• How to track JavaScript and native thread performance separately.
• Why time to interactive (TTI) matters, and how to reduce it with lazy loading, Hermes, and real-time monitoring tools.

Tools and techniques for reliable performance measurement

• How to use Flipper, Xcode Instruments, Android Studio Profiler, and Shopify’s React Native Performance library.
• What to know about JavaScript bundles vs. app bundles, and how to reduce both.
• When to use real user monitoring tools like Sentry or Firebase to gather production data.

Real-world optimization strategies with measurable impact

• How Callstack helped a sports betting app cut TTI in half by switching runtimes and removing bottlenecks.
• What Dream11 did to reduce memory pressure and improve chat UX on low-end Android devices.
• How image compression, smarter caching, and dependency audits led to smaller builds and better load times.
