Mobile App CI/CD
Ship mobile apps with confidence
We automate your mobile build, test, and release pipeline with Expo, EAS Build, and GitHub Actions. One push to main builds iOS and Android, uploads to the stores, and delivers over-the-air updates to your users.
Mobile CI/CD capabilities
From local builds to fully automated App Store deployment, all managed through GitHub.
Expo and EAS Build pipelines
We configure Expo Application Services (EAS) Build to produce iOS and Android binaries from a single React Native codebase. Profiles for development, preview, and production control signing, versioning, and optimisation automatically.
App Store and Google Play submission
EAS Submit automates uploads to App Store Connect and Google Play Console. Metadata, screenshots, and release notes are version-controlled alongside your code. No more manual uploads or missed fields.
Over-the-air (OTA) updates
EAS Update delivers JavaScript bundle updates to users without an app store review cycle. Critical bug fixes and content changes reach users in minutes, not days. Update channels let you target specific user groups.
GitHub Actions integration
Mobile builds and submissions trigger from GitHub Actions workflows. Pull requests build preview APKs/IPAs for QA. Merges to main trigger production builds and store submissions automatically.
Code signing and credentials
EAS manages provisioning profiles, certificates, and keystores. No more sharing signing credentials over email. Credentials are stored securely and rotated when needed.
Testing and QA distribution
Internal distribution builds for iOS (ad-hoc) and Android (APK/AAB) go directly to testers. TestFlight and Google Play internal testing tracks are configured for staged rollouts before public release.
From manual builds to automated releases
We assess your current process, automate the pipeline, and get your first automated release shipped.
Pipeline assessment
We review your existing mobile build process, app store presence, code signing setup, and release cadence. You receive a clear plan for automating your mobile CI/CD pipeline.
Build and submit setup
We configure EAS Build profiles, set up code signing, and wire up EAS Submit to your App Store Connect and Google Play Console accounts. GitHub Actions workflows are created for automated builds on push.
OTA and distribution
We configure EAS Update channels for over-the-air updates and internal distribution for QA. Preview builds are linked to pull requests so testers can validate changes before merge.
Go live and iterate
Your first fully automated release goes through the pipeline. We validate the end-to-end flow and iterate on build times, caching, and notification hooks. Ongoing support is available through our managed support service.

Frequently asked questions
What is Expo?
Expo is a platform built on top of React Native that simplifies mobile app development. It provides a managed workflow (no Xcode or Android Studio required for most tasks), a suite of pre-built native modules, and EAS (Expo Application Services) for building, submitting, and updating apps in the cloud.
Can Expo handle enterprise requirements?
Yes. Expo supports custom native modules, private npm registries, environment-specific configurations, and enterprise-grade code signing. EAS Build runs on dedicated infrastructure, and builds can target specific SDK versions and native dependencies.
How do OTA updates work?
Over-the-air (OTA) updates replace the JavaScript bundle in your app without requiring a new app store submission. When a user opens the app, it checks for updates and downloads the new bundle in the background. This works for UI changes, bug fixes, and content updates, but not for native module changes (which still require a new binary).
How long does an EAS Build take?
A typical iOS build takes 10-20 minutes and an Android build takes 5-15 minutes on EAS Build. Build times depend on the size of your native dependencies and caching configuration. We optimise caching and build profiles to minimise wait times.
Do you support bare React Native (non-Expo)?
Yes. While we recommend Expo for most projects, we also work with bare React Native and can set up Fastlane-based build and submission pipelines for teams that need full native control. We can also migrate bare projects to Expo if the benefits outweigh the migration effort.
Can we automate App Store screenshots and metadata?
Yes. We version-control app store metadata (descriptions, keywords, screenshots, release notes) alongside your code. EAS Submit uploads this metadata during submission. Changes to store listings go through the same pull request review process as code changes.
