You can shorten the path from a working React Native project to a testable app by keeping the first release small, setting up signing and store accounts early, and automating builds and uploads. Expo Application Services (EAS) is one option—even for projects not originally created with Expo. But faster builds do not guarantee a public launch in days: store listings, testing, review, and release decisions still take time and remain partly under Apple’s and Google’s control.
Start with the smallest useful release
Choose a clear vertical slice: the minimum set of features that makes the app useful and can be built, installed, tested, and reviewed. Defer optional native integrations unless they are essential. Each one can add configuration and testing work, so adding them late can undermine an otherwise simple release.
Decide who owns the release tasks as well as the code. Someone needs to prepare the store listing, screenshots, metadata, and release notes, select the build, respond to issues, and submit for review. These jobs can run alongside development rather than waiting for the binary to be finished.
Choose a development loop that fits your project
Expo defines an “Expo app” as a React Native app that uses Expo tools; it does not have to start with create-expo-app. EAS Build supports projects made with other common bootstrappers, including npx react-native, create-react-native-app, and Ignite. Using Expo tools does not by itself require rewriting the application. See Expo’s first-build guide.
#1 Best Overall
Use a development build for iteration
Expo describes a development build as a debug app that includes expo-dev-client. It supports a flexible development loop and is intended for rapid iteration. You can create one with EAS Build in the cloud or follow Expo’s documented local build route. Internal distribution can also help you share a build with testers before public release; see Expo’s development workflow overview.
Keep development and production artifacts distinct
A development build is for working on and testing the app; a production build is a release artifact. A successful production build or store upload is not equivalent to a store-approved public release. Keep the testing loop moving while someone prepares production metadata and release steps.
Set up store accounts and signing before release week
Store developer accounts and signing credentials are prerequisites for store builds and submissions. EAS CLI can help manage signing credentials, but it does not replace the accounts. Expo’s production-build documentation, accessed October 7, 2026, lists a one-time USD 25 Google Play Developer membership fee and a USD 99 Apple Developer Program membership requirement for production builds for Apple’s App Store. Fees and account requirements can change, so check the current platform and Expo documentation before budgeting or starting enrollment: Build your project for app stores.

Waiting until the app is ready to test can turn administrative setup into a release blocker.
Build the production binary
With EAS CLI configured, Expo documents these platform commands:
eas build --platform androidbuilds for Android.eas build --platform iosbuilds for iOS.eas build --platform allbuilds for both platforms.
Android store submissions generally use an Android App Bundle (.aab); iOS distribution uses a signed .ipa. Builds can also be made locally, and Expo says production builds can use any CI service capable of compiling Android and iOS apps. For setup and production options, see Expo’s build guide.
Rank #3
Expo says builds for a small app trigger within a few minutes. That is Expo’s estimate for build triggering, not a guarantee of total build time, successful processing, store approval, or public release. Build duration and end-to-end release timing are different questions.

Automate the upload, then follow the platform’s release path
EAS Submit can upload correctly signed binaries, including binaries built outside EAS Build. Expo documents eas build --auto-submit as an option to build and automatically upload binaries. It reduces manual handoffs; it does not submit all metadata, secure approval, or publish the app by itself. The platform-specific outcomes differ:
| Platform | What upload does | What remains |
|---|---|---|
| Android | EAS Submit sends the .aab to a selected Google Play Console track. For a brand-new app, the default can create an internal testing release. |
Complete the Play Console listing and setup, test the release, and promote it beyond internal testing when ready. |
| iOS | EAS Submit sends the signed .ipa to App Store Connect. After processing, the build becomes available in TestFlight. Expo gives a usual processing estimate of 10–15 minutes; it is not an App Review or launch estimate. |
Complete metadata and screenshots, select the build, and submit it for App Review. The default automated submission goes to TestFlight, not App Store review; promotion to review remains a manual step. |
See Expo’s submission guide and submission automation guide for the documented behaviors. An iOS upload available in TestFlight is not automatically an App Store review submission.
Choose EAS, local builds, or existing CI
| Route | Useful when | What your team still owns |
|---|---|---|
| EAS Build plus EAS Submit | You want cloud builds, signing assistance, store uploads, and integration with Expo workflows or CI. | Store accounts, listing and screenshot preparation, testing, and platform-controlled review and release. Android track selection and iOS TestFlight-to-review steps differ. |
| Local or native builds with manual upload | You want direct control or already have a native release process. | Platform tooling, signing, and upload. React Native documents an iOS route using Xcode’s Release scheme, an archive, App Store Connect upload, required information, and review submission. |
| Existing CI with an Expo build workflow | Your team already operates CI and wants compilation to remain in that system. | Build configuration, signing, store access, listing work, and release operations. |
EAS is optional, not a requirement for React Native. For the direct iOS route, follow the React Native publishing guide, last updated August 12, 2026. For EAS’s current service scope, see Expo Application Services.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Test and prepare the listing in parallel
Use development or internal builds to get feedback before public launch. Create a release checklist that assigns an owner to each of these items:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Tester access and a process for collecting and triaging feedback.
- Store listing text, screenshots, and required app metadata.
- Release notes and the production build to submit.
- Play Console track selection and any needed promotion from testing.
- App Store Connect build selection and App Review submission.
EAS Submit handles binary uploads, not store listing metadata or screenshots. Keep those tasks visible in the schedule instead of treating an upload as the finish line.
Launch, monitor, and update carefully
After release, plan how the team will notice crashes and other production problems. Expo’s workflow overview names crash reporting and analytics as monitoring categories and lists Sentry and BugSnag as possible crash-reporting options; it does not compare their costs or performance.
Expo also describes expo-updates and EAS Update as ways to deliver JavaScript updates to production apps. Do not assume every change can bypass store review: native-code, entitlement, and store-policy changes may require a new store build and must follow the applicable platform process. See Expo’s workflow overview and EAS documentation.
What “days, not months” can—and cannot—mean
The controllable work is the project’s scope, development and testing loop, account readiness, build process, and upload handoffs. EAS or a capable CI service can automate parts of compilation and submission, while store preparation and testing proceed in parallel. None of that establishes a reliable number of days from a working project to public availability: build triggering, upload processing, review, testing, and rollout are separate stages, and no guaranteed end-to-end timeline is established here.
