For teams developing scalable mobile applications, efficient delivery is paramount. As mobile development becomes increasingly complex, many teams find themselves relying on manual workflows for deployment.
While this approach might be sufficient in the early stages, it can quickly lead to a range of challenges like slower release cycles, inconsistent results across Android and iOS platforms, delays in hotfixes or updates, and bottlenecks in QA testing.
As the need for faster and more reliable deployments intensifies, traditional manual processes are no longer feasible.
This is where Expo Application Services (EAS) comes into play. By integrating EAS into a React Native workflow, teams can significantly streamline the deployment process. Expo EAS enables faster builds, reduced release times, and modern CI/CD practices that automate the entire delivery pipeline.
In this blog post, we’ll walk through a typical deployment journey, showcasing how Expo EAS transforms the process. From manual operations to fully automated delivery, this solution not only addresses the common pain points of mobile deployment but also enhances the overall efficiency of the development pipeline.
The Challenge: Manual Workflows Hinder Delivery
Many mobile development teams start their journey with manual workflows, handling each step of the deployment process manually. While this may seem like a manageable solution in the early stages, it quickly becomes clear that manual workflows present significant challenges as projects scale.
Teams often face a number of roadblocks, including:
Slower Release Cycles
The reliance on manual processes for triggering builds, testing, and deployments creates delays at each stage of the workflow. Teams must wait for individual approvals, handle tasks manually, and troubleshoot any issues, all of which add unnecessary time to the release cycle.
Inconsistent Results Across Android and iOS Platforms
Without automation, the same build process might be executed differently on Android and iOS. This can lead to inconsistencies in app performance and behavior, making it harder to ensure that the app delivers a seamless experience across all platforms.
Delays in Deploying Hotfixes or Updates
When urgent issues arise, manual workflows can make it difficult to quickly deploy hotfixes or updates. The need for manual intervention can delay the process, causing teams to miss critical windows for quick fixes or updates.
Limited Integration with CI/CD Pipelines
Teams may lack the tools or infrastructure to integrate their build and deployment processes with CI/CD pipelines. This lack of automation means that each step, including build, test, and deploy, must be handled separately, resulting in inefficiencies and potential errors.
Bottlenecks in QA Testing and Feedback Loops
In a manual workflow, QA teams are often dependent on manual build submissions. This slows down the feedback loop, making it harder to catch bugs early in the process. As a result, issues might not be discovered until later in development, affecting the overall quality of the app.
The Solution: Streamlined Delivery with Expo EAS
Adopting Expo Application Services (EAS) provides a scalable solution to the challenges faced by teams relying on manual workflows. Expo EAS integrates seamlessly into the React Native development process, offering a modern approach to app delivery that eliminates the bottlenecks and inefficiencies of traditional methods.
By incorporating tools like GitHub Actions, EAS enables fully automated, cloud-based workflows, ensuring that teams can deploy apps with greater speed, reliability, and consistency.

CI/CD Integration
Expo EAS integrates with GitHub Actions, enabling automatic build triggers. This eliminates the need for manual intervention at every stage, reducing the time it takes to go from development to deployment. Automated workflows ensure faster and more efficient updates, ensuring that your app is always up-to-date.
-
Cloud-Based Builds
With Expo EAS, there’s no need to rely on local machines to generate builds. Cloud-based builds enable teams to access faster, more scalable resources, ensuring that builds are created consistently without the constraints of local environments. This approach minimizes the risk of errors due to machine inconsistencies.
-
Over-the-Air (OTA) Updates
Expo EAS allows teams to deploy instant patches without waiting for the app store review process. OTA updates ensure that bug fixes or minor updates can be delivered immediately, improving the user experience and speeding up response times to critical issues.
-
Environment Profiles
With Expo EAS, teams can set up separate dev, staging, and production environments. This allows for more precise control over builds, ensuring that the right configurations are used at each stage of the deployment process. Separate profiles help prevent issues related to mismatched environments during development and testing.
-
Seamless App Store Deployment
Expo EAS allows for the direct submission of builds to TestFlight and Google Play. This integration streamlines the process, removing the need for manual steps to distribute builds. Teams can submit builds quickly and easily to both Apple TestFlight (iOS) and Google Play Console (Android), enabling faster testing and release cycles.
Seamless Deployment to TestFlight and Google Play
One of the most powerful capabilities of Expo EAS is the ability to submit builds directly to Apple TestFlight and Google Play Console using the eas submit command.
This drastically simplifies and accelerates mobile app distribution, reducing the friction between development and testing, and improving feedback loops across platforms.
Below are the supported distribution channels.
TestFlight (iOS)
- With direct integration, internal and external testers can receive new builds within minutes.
- The process of pushing updates for review or QA becomes seamless, and because feedback loops are much tighter before public release, teams can iterate faster.
- Expo EAS enables smoother and faster iOS testing, eliminating the need for manual uploads through Xcode or Apple’s Transporter tool.
Google Play Console (Android)
- Expo EAS supports the submission of .aab (Android App Bundle) builds directly to various Google Play tracks (Internal, Closed, or Production).
- This enables controlled rollouts, early feedback collection, and automated delivery.
- Developers no longer have to manage APK generation or log into the Play Console manually, saving time and reducing errors.
This direct integration into both app ecosystems helps developers streamline mobile CI/CD even further. With eas submit, your team can confidently automate the final leg of deployment, from build generation to store delivery, ensuring faster releases, less manual work, and greater reliability in your mobile delivery pipeline.
Credentials and Signing Made Easy
Managing credentials and app signing can be one of the more cumbersome and error-prone aspects of mobile app deployment. From provisioning profiles to signing keys, developers must ensure all credentials are correctly configured to successfully submit apps to the App Store or Google Play.
Expo EAS streamlines this complex process, offering both automatic and manual credential management options, so teams can focus on building apps, not managing secrets.
iOS Credentials
Expo EAS supports a range of iOS credentials, including .p12 certificates, provisioning profiles, and App Store Connect API keys.
With EAS, developers can automate the generation, upload, and management of these credentials, removing the need for manual configuration through Xcode or the Apple Developer Portal.
- Automated iOS credential management ensures that the right certificates and provisioning profiles are always used for builds, reducing the risk of errors during deployment.
- App Store Connect API keys can be automatically configured to interact with EAS, allowing for smoother interactions with the App Store Connect platform.
Android Credentials
For Android, Expo EAS simplifies the process by supporting the upload of signing keys and Google Play JSON service account credentials. EAS handles the encryption and secure storage of these credentials, ensuring that app signing is managed in a secure, efficient manner.
- Automatic key management for Android helps eliminate the possibility of misconfigurations that might otherwise delay the submission process.
