Release Architecture

Three Services. Three Stages. One Continuous Model.

Stage 01 • Compilation

EAS Build

Creates the native binary in Expo's cloud infrastructure from your repository and build profiles.

Output: Native IPA & AAB binaries
Stage 02 • Distribution

EAS Submit

Automates store delivery to App Store Connect and Google Play using stored secure credentials.

Target: Apple & Google Review
Stage 03 • Continuous Fixes

EAS Update

Delivers compatible JavaScript bundles and assets to active binaries without review cycles.

Velocity: Can be delivered quickly; rollback timing varies by device

Build and Submit govern the native binary shell. EAS Update creates a fast, independent second highway for the JavaScript layer.
