React Native powers apps used by millions — Facebook, Instagram, Shopify, Discord, and Microsoft Teams all use React Native in production. It lets your web React team build native iOS and Android apps without learning Swift or Kotlin, while sharing business logic, API clients, and even UI components with your web frontend. With the New Architecture (Fabric renderer + JSI), React Native's performance gap with native has narrowed dramatically.

Why It Matters

Key benefits for your business

🔧

JavaScript & TypeScript Familiarity

Your existing React web developers can build production mobile apps without hiring dedicated iOS and Android engineers. TypeScript catches bugs at compile time across both platforms.

🔗

Code Sharing with Web React

Share Redux stores, React Query hooks, TypeScript types, validation logic, and even UI components between your React web app and React Native mobile app — one team, two platforms.

📦

Massive npm Ecosystem

Access to 1.5 million npm packages plus a thriving React Native community on GitHub. Navigation, forms, animations, payments, maps, camera — there's a battle-tested package for everything.

🔄

OTA Updates via CodePush

Push JavaScript bundle updates to users instantly via CodePush — no App Store or Play Store review required for bug fixes and minor feature updates. Critical fixes reach all users in minutes.

⚡

Faster Iteration Cycles

Hot reloading, a shared JavaScript debugging environment, and Jest-based unit testing mean faster feedback loops. Features ship to both iOS and Android in the same sprint.

🏢

Meta + Microsoft Backing

React Native is maintained by Meta's open-source team with significant contributions from Microsoft (Windows support), Shopify, and Callstack. Long-term stability is well-funded.

Our Process

How we deliver results

01

Architecture & Tech Stack Decision

We define whether to use Expo or bare React Native, choose state management (Redux Toolkit vs React Query vs Zustand), and architect the project structure for scalability and web code sharing.

02

UI Design & Component Library

Figma designs with a shared component library. We map components to React Native primitives early to ensure designs are implementable without platform-specific hacks.

03

TypeScript Development

Development with TypeScript strict mode, ESLint + Prettier, Jest unit tests, and Detox E2E tests. Native module bridging in Swift/Kotlin only where npm packages fall short.

04

EAS Build, Testing & Store Submission

Expo Application Services or custom Fastlane pipelines for automated iOS and Android builds. Device testing, store submission, and CodePush configuration for post-launch updates.

FAQ

Frequently asked questions

React Native vs Flutter vs native — how do I choose?
React Native is best when your team knows JavaScript/TypeScript, you have a React web app to share code with, or you need OTA updates. Flutter is better for pixel-perfect custom UI across 6 platforms with a smaller team. Native (Swift/Kotlin) wins for maximum performance, deep OS integration, or apps with very high animation complexity.
What is the New Architecture and should I use it?
The New Architecture replaces the asynchronous JS bridge with JSI (JavaScript Interface) for synchronous native calls, and the Fabric renderer for a concurrent-mode-compatible UI layer. We enable it for all new projects — it delivers meaningfully better performance and is the future of React Native. Legacy apps can be migrated incrementally.
When does React Native make business sense?
React Native delivers best ROI when: (1) you have JavaScript developers you want to leverage for mobile, (2) you have a React web app to share code with, (3) you need OTA hotfixes (financial apps, marketplace apps), (4) you're building an MVP and want iOS+Android in one sprint.
Does React Native have performance limitations I should know about?
The main limitations: (1) computationally intensive tasks should run in native modules or worklets, not the JS thread; (2) very large lists need FlashList not FlatList; (3) complex gesture-driven animations need Reanimated worklets; (4) startup time needs Hermes + inline requires. We build around all of these by default.
How do OTA updates work with CodePush?
CodePush hosts your React Native JavaScript bundle. When you push an update, the app silently downloads the new bundle on next launch and applies it — no App Store/Play Store submission needed. We use this for bug fixes, copy changes, and minor features. Major changes (new native modules, app icon changes) still require a full store release.
Do you use TypeScript in all React Native projects?
Yes — TypeScript strict mode on every project. We type API responses with Zod for runtime validation, use typed React Navigation for compile-time route safety, and type Redux state and thunks fully. Untyped React Native code is a maintenance debt we refuse to create.
