syntaqxThe phone app builds for Android on EAS from a workflow, so testers install it from a QR code before Google Play. mobile-build.yml runs by hand (preview, the default, or development) and on main when the app's native side changes; its summary links the build's page on expo.dev, whose QR code installs the APK, and the APK itself. Preview is g1t (beta), a standalone signed APK anyone with the link can install; code changes reach it over the air on the preview channel.39342daHistory
