  "account": "A single over-the-air update reaching all users simultaneously is a single point of failure that creates a dangerous risk. Fixing a typo on the checkout screen and publishing the update can result in a crash dashboard filled with red errors, which is only fixable after all users have downloaded the update. Staged rollouts address this issue by releasing updates to a small segment of users first, monitoring crash and behavior data, and then gradually expanding the rollout based on the results. This approach is similar to the discipline web teams have learned with canary deployments, tailored for Expo OTA updates where feedback is slower and the consequences of a bad push are more severe.\n\nTo implement staged OTA rollouts with EAS Update channels and branches, there is a recommended ramp sequence consisting of four stages. The first stage involves internal testing, where the update is published to an internal channel consumed by team devices and internal builds. This stage allows for manual testing and catching any embarrassing bugs before real users are involved. The internal dwell period is at least one working session.\n\nIn the second stage, a small canary group of users (1-5%) receives the update. This stage should be monitored for 24 hours to account for diurnal mobile usage patterns. Crash-free sessions and specific screens touched by the update should be closely watched during this stage.\n\nThe third stage expands to early majority users (25-50%), allowing for further testing while catching larger device-fragmentation issues. This stage is crucial for identifying any problems that may have been missed in the previous stages. The full production rollout (100%) should only occur after monitoring for an additional 48 hours to catch any long-tail issues, such as expired cached assets or users who launch the app infrequently.\n\nTo ensure a successful staged rollout, it's essential to keep an eye on three key metrics at each gate: crash-free sessions (compared to a baseline cohort), release health specifically related to the touched flows (e.g., checkout completion and error rates), and other general release-health monitoring for AI-built apps. By following this disciplined approach, teams can minimize the risk associated with all-at-once OTA updates while maintaining the speed and efficiency provided by tools like EAS Update.",
  "summary": "An over-the-air update that reaches every user at once is a single point of failure wearing a shipping shortcut as a disguise. You fix a typo in the checkout screen, tap publish, and ten minutes later your crash dashboard is a wall of red — on an update you can roll back, but only after everyone already downloaded it. Staged rollouts fix this. Instead of publishing an EAS Update to your whole…",
