Expo specialists for your dedicated team.

When an app needs Expo skills.

Expo is the standard way to start a React Native app today, and React Native's documentation recommends a framework like it. The harder case is an older app. It's a bare React Native project several versions behind, with native folders edited by hand and upgrades that take weeks. Moving it to Expo's prebuild model with config plugins makes the next upgrades routine.

Release speed is another reason. If a one-line fix needs three days to reach users because of builds and store review, EAS Update can deliver JavaScript changes within the hour.

Small teams gain the most. With EAS Build, the team doesn't need a Mac kept on the right Xcode version to produce the iOS binary.

What our Expo developers ship in a sprint.

• SDK upgrades Taking the app to the current Expo SDK and its React Native version. That includes the move to the New Architecture and replacing libraries that don't support it.
• Navigation Building screens with Expo Router: file-based routes, deep links and typed navigation that also runs on the web.
• Native features Adding push notifications, camera, biometrics or in-app purchases through Expo modules and config plugins. Where no library exists, they write a small Swift or Kotlin module with the Expo Modules API.
• Build and submit Setting up EAS Build profiles for development, preview and production, with EAS Submit sending builds to TestFlight and Google Play from CI.
• Over-the-air updates Configuring EAS Update channels and runtime versions so a JavaScript fix only reaches binaries it is compatible with, with staged rollout and rollback.
• Testing Running Jest and React Native Testing Library on every commit, and end-to-end flows in Maestro or Detox on development builds.

An app is never finished, because iOS, Android and the stores change every year. Companies that hire mobile developers through us get React Native developers who stay on one app, full time. They're managed by us, and you pay the same fee every month.

Expo mistakes that reach your users.

The serious one is an over-the-air update that expects native code the installed app doesn't have. The JavaScript loads, calls a module that isn't there, and the app crashes on start. Runtime versions tied to the native build prevent it. A careful developer also tests each update on the oldest binary still in the stores.

Staying on Expo Go too long is a slower problem. It only contains Expo's own native modules, so the first third-party SDK forces a change of workflow. Starting with development builds from day one avoids the detour.

Skipped SDK releases add up. Expo ships several SDKs a year and supports each for a limited time, while Apple and Google raise their build requirements every year. One upgrade per release is a small job, and three at once is a project.

What buyers ask about Expo.

• Is Expo good enough for a production app? Yes. The old limits are gone. Development builds and config plugins let an Expo app use any native library, and you can still open Xcode or Android Studio when needed.
• Do we still need native iOS and Android skills? Less often, but yes. Somebody on the team should be able to read a crash log from Xcode, write a config plugin and sort out signing certificates. We look for React Native developers with that depth.
• Can over-the-air updates skip app store review? For JavaScript and assets, yes, within the stores' rules: an update can't change what the app is for. Anything that touches native code, permissions or the SDK version needs a new binary and a normal review.
