What problem does it solve? Releasing a mobile app to the iOS App Store and Google Play involves complex credential management, version numbering, store metadata, and submission tooling. This Skill guides the full EAS build-and-submit pipeline so Expo apps reach production stores without manual portal work. ## Core Features & Use Cases - Store Builds & Submissions: Run eas build and eas submit with production profiles for iOS App Store, Google Play, and TestFlight. - Configuration Management: Set up eas.json build and submit profiles, remote version source, auto-incrementing build numbers, and store credentials. - Metadata & ASO: Manage App Store listing metadata, keywords, localization, and release strategy via EAS Metadata and store.config.json. - Use Case: You are ready to ship your Expo app. Use this Skill to configure eas.json, produce production builds for both platforms, submit to TestFlight for beta testing, and push localized store metadata before release. ## Quick Start Ask the assistant to build and submit your Expo app to TestFlight and the Google Play internal track using EAS production profiles.
