What problem does it solve? Releasing mobile apps to the Apple App Store and Google Play involves complex signing, versioning, submission, and review steps. This Skill guides the full EAS build-and-submit pipeline so releases reach TestFlight, the App Store, and Google Play without manual portal guesswork. ## Core Features & Use Cases - EAS Build & Submit Pipelines: Configure eas.json profiles, run production builds, and submit binaries to App Store Connect and Google Play with auto-submit or explicit build IDs. - Store-Specific Guidance: Detailed references for TestFlight beta testing, iOS App Store review and release, Google Play tracks and staged rollouts, and App Store metadata/ASO via store.config.json. - Native iOS Support: Covers SwiftUI/UIKit apps without a React Native runtime, including archive verification, CFBundleVersion troubleshooting, and icon alpha-channel checks. - Use Case: A team with an Expo app needs its first production release. Use this Skill to configure eas.json, build for both platforms, submit to TestFlight and the Play internal track, then complete App Review and a staged rollout. ## Quick Start Use the eas-app-stores skill to configure eas.json and build and submit my app to TestFlight and Google Play.
