What We Build with React Native

React Native renders to native UI components, not a WebView, so apps look and feel genuinely native on both iOS and Android. Your team writes JavaScript or TypeScript, and React Native bridges to the platform's native layer for real native performance.

The practical advantage is team efficiency: web developers can contribute to mobile, you share business logic between web and mobile, and the vast npm ecosystem is available. For apps with existing React web teams or shared logic, React Native frequently delivers faster time-to-market.

⚛️

JS/TS Native Apps

React and TypeScript for both platforms. Web developers can contribute directly without separate mobile specialisation.

🔌

Huge Ecosystem

The npm ecosystem plus React Native's own package library covers almost every mobile use case.

⚡

Expo Managed Workflow

Expo dramatically reduces build complexity. OTA updates, managed builds, and easy CI/CD without native toolchain knowledge.

🌐

Web Code Reuse

Share validation, state management, API clients, and business logic between your React web app and React Native mobile app.

What We Deliver

Full React Native Development Service

From TypeScript architecture to dual-store submission.

⚛️

TypeScript & React Native UI

Strict TypeScript, React hooks, functional components, and React Navigation for a clean, maintainable codebase.

⚡

Expo & EAS Build

Expo managed workflow with EAS Build for cloud-based iOS and Android builds. OTA updates to push JS changes without a store release.

🔌

State Management

Redux Toolkit, Zustand, or React Query depending on data patterns. Clean separation of UI from business logic.

💰

Payments & Subscriptions

React Native IAP, Stripe SDK, and RevenueCat for subscription management across both platforms.

📊

Performance Optimisation

Hermes engine, FlatList virtualisation, image caching, memoisation, and native modules for compute-heavy tasks.

🌐

Web & Mobile Shared Code

Shared TypeScript types, API clients, validation logic, and state management between React web and React Native apps.

Our Process

How We Build Your React Native App

From TypeScript architecture to both stores.

📝1

Architecture & Setup

TypeScript config, navigation structure, state approach, Expo vs bare workflow decision, and backend API design.

🎨2

Component Design

Design system in Figma mapped to reusable React Native components. Platform-adaptive behaviour specified per component.

⚙️3

Sprint Development

Two-week sprints. Expo Go or TestFlight / APK preview at every sprint end for simultaneous cross-platform review.

🧪4

QA Both Platforms

Functional testing on real iOS and Android devices. JS bundle performance and native module behaviour verified.

🚀5

Dual Store Launch

EAS Submit for automated App Store and Play Store submission. Both stores managed simultaneously.

Why Nine Pixels

Why Studios Choose Us for React Native

Production React Native experience across consumer and enterprise apps.

⚛️

TypeScript-First

We write strict TypeScript React Native. No JavaScript escape hatches. Type safety catches issues before QA, not after.

⚡

Expo Expertise

We've used Expo from its early versions. We know when managed workflow is the right choice and when to eject to bare workflow.

📊

Performance Engineering

We address JS thread blocking, unnecessary re-renders, and image memory proactively, not after a Play Store review flags them.

🌐

Web Team Integration

We structure the mobile codebase to let your React web team contribute. Shared packages, aligned patterns, unified TypeScript types.

FAQ

React Native FAQs

Common questions about React Native development with Nine Pixels.

React Native vs Flutter - which should I choose?+

React Native if: you have a JavaScript/React web team, want to share code with a web app, or your app uses many third-party JS integrations. Flutter if: you want maximum UI consistency and custom animation quality, or performance is the top priority. We advise based on your specific situation.

Is React Native performance as good as native?+

For most UI-driven apps, yes. The Hermes engine, JSI architecture, and Reanimated 3 deliver native-quality performance for standard app use cases. For very compute-heavy tasks, native modules bridge to platform code.

Can we use Expo for production apps?+

Yes. Expo's managed workflow is production-ready and used by major apps. EAS Build produces native iOS and Android binaries.

Can we share code between our React web app and React Native app?+

Yes. Business logic, TypeScript types, API clients, validation, and state management can be shared via a shared package in a monorepo.

Do you handle OTA (over-the-air) updates?+

Yes. Expo EAS Update allows JS bundle updates without a store release. We set up and manage the OTA update pipeline as part of the project.

Can you take over an existing React Native project?+

Yes. We review the codebase, React Native version, Expo configuration, and native module dependencies before committing.
