Hire React Native developers to ship iOS and Android from one codebase

Dware's senior React Native developers build iOS and Android apps in TypeScript with Expo, so you launch on both stores with one team. We set up EAS builds, over-the-air updates and native modules where your app needs them. If you already have a React web app, we share code with it instead of starting again.

  • One TypeScript codebase for iOS and Android
  • Expo, EAS Build and over-the-air updates set up properly
  • Native Swift and Kotlin modules when JavaScript is not enough

Overview

Why companies choose React Native developers

React Native lets you build real iOS and Android apps with React and TypeScript. It is not a website wrapped in an app. Your components render as true native views, so lists scroll, keyboards behave and gestures feel the way users expect. Because one codebase drives both platforms, one team can ship features to iPhone and Android users on the same day, and you maintain one set of business logic instead of two.

The framework has matured a lot. The New Architecture, with Fabric rendering and TurboModules over JSI, is now the default, and the Hermes engine makes apps start faster and use less memory. Expo, which the React Native team itself recommends for new apps, adds file-based routing with Expo Router, a large set of maintained native libraries, and EAS for cloud builds, store submission and over-the-air updates. Our developers build on this modern stack, not on patterns from five years ago.

React Native is a strong fit when you already use React on the web. Your web developers can read and review the mobile code, and we can share TypeScript types, API clients, validation schemas and business rules between your website and your app in one monorepo. Bugs get fixed once. Features stay consistent. Hiring is easier too, because React and TypeScript skills are common.

It still takes real mobile skill to do well. Good React Native developers know when a screen needs Reanimated for smooth animation, when a list needs FlashList, how to write a native module in Swift or Kotlin, and what Apple will and will not accept in an over-the-air update. They read Xcode build logs and Gradle errors without panic. That mix of React depth and native knowledge is what we vet for.

What we build

React Native development services

We cover the full life of a React Native app, from the first prototype to years of updates.

  • New React Native apps with Expo

    We start new apps with Expo, Expo Router and TypeScript, using development builds rather than Expo Go so any native library can be added later. You get a clean project structure that new developers can understand on day one.

  • Sharing code with your React web app

    We set up a monorepo with pnpm or Yarn workspaces and Turborepo, with shared packages for types, API clients, Zod schemas and business logic. Where it makes sense, Expo Router and React Native Web let some screens run on the web as well.

  • Native modules in Swift and Kotlin

    When a feature needs a platform API or a vendor SDK with no React Native package, we write the native module ourselves with the Expo Modules API or a Turbo Native Module. Config plugins apply the native setup automatically, so builds stay reproducible.

  • EAS Build, Submit and Update pipelines

    We configure EAS profiles for development, preview and production, manage signing credentials, and connect builds to GitHub so every merge can produce a test build. EAS Submit uploads to App Store Connect and Google Play without manual steps.

  • Over-the-air updates

    We set up EAS Update with channels, runtime versions and staged rollouts, so JavaScript and asset fixes reach users within hours. We also define what must go through store review, keeping you inside Apple's and Google's rules.

  • Upgrades and New Architecture migration

    We upgrade old React Native and Expo SDK versions step by step, replace abandoned libraries, and move apps to the New Architecture and Hermes. Each step ships as a tested build, not one risky big-bang change.

  • Performance tuning

    We profile slow screens with React Native DevTools and the native profilers, then fix the cause: unnecessary re-renders, heavy lists, oversized images or work on the JavaScript thread that belongs on the UI thread.

  • Payments, push and device features

    We implement in-app subscriptions with RevenueCat, physical-goods payments with Stripe, push with Expo Notifications or Firebase, plus camera, maps, biometrics and background location, all tested on real devices.

Our process

How our React Native developers build your app

Here is the path from idea to both stores, with the React Native specific work at each step.

  1. 1

    Discovery and a native capability check

    We list your features and check each device capability against the React Native ecosystem. Most needs, like camera, maps, push and payments, have mature Expo or community libraries. Anything without one, like a niche hardware SDK, gets flagged early with a plan for a custom native module. We also confirm React Native is the right choice for your app and say so if it is not.

    What you get

    • Feature and library map
    • Native module plan
    • Fixed quote and timeline
  2. 2

    Design for both platforms

    We design in Figma with a shared component set, then decide where iOS and Android should differ, such as navigation headers, date pickers, sheets and back gestures. We define a design token file that maps straight into the app's theme, and, if you have a web app, into the web codebase too. You test a clickable prototype before development starts.

    What you get

    • Figma prototype
    • Shared design tokens
    • Platform difference notes
  3. 3

    Architecture and project setup

    We create the Expo project with TypeScript in strict mode, Expo Router for navigation and a clear folder structure. We pick state tools to suit your app, typically TanStack Query for server data and Zustand or Redux Toolkit for local state, with MMKV or SQLite for offline storage and SecureStore for tokens. EAS profiles, environment variables and signing are set up in your Apple and Google accounts in week one.

    What you get

    • Repository with CI
    • EAS build profiles
    • Architecture notes
  4. 4

    Building features in sprints

    We build in two-week sprints. Every pull request runs type checks, ESLint and Jest in CI, gets a senior code review, and can produce a preview build or EAS Update you open on your phone. Native code is kept small and isolated in modules with typed interfaces. You see working features on real devices every week, not screenshots.

    What you get

    • Preview builds per sprint
    • Reviewed pull requests
    • Sprint demo and notes
  5. 5

    Testing on real iPhones and Android phones

    We write unit and component tests with Jest and React Native Testing Library, and end-to-end tests for key flows with Maestro or Detox. Then we test by hand on physical devices: a recent iPhone, an older iPhone, a flagship Android and a low-end Android, because performance on cheap Android hardware is where React Native apps are most often judged. We use release builds with Hermes for this, since debug builds behave differently.

    What you get

    • Automated test suite
    • Device test report
    • Performance baseline
  6. 6

    TestFlight and Google Play internal testing

    EAS Submit sends builds to TestFlight and to Google Play's internal and closed testing tracks. Your team and beta users install them like any app. For newer personal Google Play accounts, we run the required closed test with at least 12 testers for 14 days. Sentry captures crashes with source maps, so every error points to the real line of TypeScript.

    What you get

    • TestFlight and Play test tracks
    • Crash reporting with source maps
    • Beta feedback fixes
  7. 7

    Store release

    We prepare listings, screenshots, Apple privacy labels and Google's Data safety form, including the data collected by every library in the app. We submit, respond to review notes and release with phased rollout on iOS and staged rollout on Android. The production EAS Update channel is tied to the exact runtime version of the store build, so later updates only reach compatible installs.

    What you get

    • Approved store builds
    • Store listings
    • Production update channel
  8. 8

    Over-the-air updates and long-term upkeep

    After launch, JavaScript and asset fixes ship through EAS Update, first to a small percentage of users, then to everyone. Changes to native code or permissions go through a normal store release. We upgrade React Native and the Expo SDK on a regular schedule, so you never fall years behind, and we test against each new iOS and Android release.

    What you get

    • OTA release process
    • Scheduled SDK upgrades
    • Post-launch support

Technical expertise

React Native development expertise that matters in production

Many React Native apps work in a demo and struggle in the real world. These are the areas our developers focus on.

Over-the-air updates done safely

Over-the-air updates can only change JavaScript and assets, not native code. If an update expects a native module the installed app does not have, it crashes. We prevent that with runtime versions or fingerprint checks, separate channels for preview and production, and gradual rollouts with a quick rollback. We also keep updates to fixes and improvements that do not change the app's main purpose, which is what Apple's guidelines allow.

Smooth performance on low-end Android

We use FlashList for long lists, expo-image for cached images, and Reanimated with Gesture Handler so animations run on the UI thread. We memoise expensive components, avoid passing new objects to every render, and keep heavy work off the JavaScript thread. We measure start-up time and frame rates in release builds on budget devices.

Native modules and config plugins

We follow Expo's Continuous Native Generation approach: the ios and android folders are generated from app config, and every native change lives in a config plugin. This keeps upgrades simple, because there are no hand-edited native files to merge. When we write a module, we use Swift and Kotlin with a typed TypeScript interface.

Code sharing with a web app

We share the parts that should be identical, like types, API calls, validation and pricing logic, and keep UI separate where web and mobile users expect different things. A shared package with tests means a rule changed once is changed everywhere. This is often the biggest long-term saving of choosing React Native.

Security and secrets

Anything in the JavaScript bundle can be read by a determined user, so we never ship secret API keys in the app. Sensitive calls go through your backend. Tokens live in the iOS Keychain and Android Keystore via SecureStore, and we add certificate pinning or jailbreak checks when your risk level calls for it.

FAQ

Hire React Native developers: frequently asked questions

Is React Native good enough for a serious production app?

Yes, for most apps. Large consumer and business apps run on React Native in production. With the New Architecture and Hermes now the default, performance is close to native for typical screens. It is less suited to apps built around heavy 3D graphics or the very newest platform APIs on day one. In those cases we may suggest native, or React Native with a few native modules.

Should we use Expo or bare React Native?

For nearly every new app we recommend Expo, and the React Native team recommends it too. The old limits are gone: with development builds and config plugins you can use any native library or write your own native code. You also get Expo Router, EAS Build and EAS Update. We only skip Expo for some brownfield cases, where React Native screens are added to an existing native app.

How much does it cost to hire React Native developers?

It depends on the number of screens and features, the integrations you need, whether we build the backend, how much code we can share with your web app, and your timeline. One React Native codebase usually needs less effort than two native apps for the same features. After a short call we send a free, fixed quote so the cost is clear before we start.

Can you share code between our Next.js website and the mobile app?

Yes. We set up a monorepo where the website and app import shared packages for types, API clients, validation schemas and business rules. UI is usually kept separate, because people use phones and desktops differently, but some screens can be shared through React Native Web and Expo Router where it helps. This keeps logic in sync and lets your web developers work on the app too.

Are over-the-air updates allowed by Apple and Google?

Yes, within limits. Both stores allow updates to the JavaScript and assets of an app as long as they do not change its main purpose or sneak in features that would need review. Native code, new permissions and big new features still go through the store. We set up EAS Update to follow these rules, with staged rollouts and rollback.

We used CodePush. What now?

Microsoft retired App Center, including CodePush, in 2025. We move apps to EAS Update, which works with bare React Native as well as Expo. The migration means adding the expo-updates library, setting runtime versions so updates only reach compatible builds, and shipping one store release with the new update client. After that, your team deploys updates with one command or from CI.

Our React Native app is several versions behind. Can you upgrade it?

Yes. We first audit the project: React Native and Expo versions, every library, and which ones are abandoned. Then we upgrade in steps, one or two versions at a time, replacing dead libraries and fixing native build changes along the way. Each step is tested and shipped, so the app keeps working during the upgrade. We finish with the New Architecture enabled.

How do you test React Native apps?

We use Jest and React Native Testing Library for logic and components, and Maestro or Detox for end-to-end flows such as sign-up and checkout, run in CI. Then we test release builds on real devices, including a low-end Android phone, because that is where performance problems show. Sentry with source maps tracks crashes in test builds and production.

What if we need a feature React Native does not support?

Then we write the native part ourselves. With the Expo Modules API we wrap a Swift or Kotlin SDK, or a platform API, in a typed TypeScript interface your app calls like any other function. Config plugins add the required native setup, such as permissions or Info.plist entries, so the build stays automated.
