Crash reporters tell you when the binary died. They stay quiet when an OTA makes the home screen take three seconds longer on mid-range Android. That gap is where most "the app feels worse" tickets come from — and where release blame usually dissolves into guesswork across three native builds and two JavaScript updates.

This post is the production wiring guide for EAS Observe (expo-observe): install it, call markInteractive() honestly, read release markers next to cold/warm launch and TTI, and keep Sentry (or similar) for mature crash triage.
