How is your app actually doing in production
summary
A concrete observability stack for React Native: an open-source client called Observe that sends startup metrics (launch time, bundle load, time to render, time to interactive) to an EAS Observe Collector, shows per-release and per-screen TTI comparisons, flags oversized images with URL and expected vs actual sizes, and offers an AI agent that correlates slow events with commits, builds, and packages. Crash reporting, traces, and alerts are in beta and tied to upcoming SDK 57/58 releases.
