React Native

One Codebase. Two Platforms. Full Native Performance.

We build production-grade React Native apps that feel like native apps — one JavaScript codebase, iOS and Android simultaneously, at roughly 60% of the cost of building both natively.

Why It Matters

Two Platforms at Once Is Not a Compromise — If Done Right

The most common mistake with React Native projects is treating the shared codebase as a goal rather than a means to an end. Teams write a single set of components targeting neither iOS nor Android conventions specifically — no platform-adaptive navigation, no platform-specific interaction patterns — and ship an app that feels foreign on both platforms. React Native gets blamed for the result, when the real cause is treating cross-platform as 'write once, ignore both'.

This matters because iOS and Android users have fundamentally different expectations. iOS users expect swipe-back navigation, bottom tab bars following Apple's HIG, and modal sheets that match system behaviour. Android users expect back-button handling, navigation drawers in enterprise contexts, and FABs following Material Design placement conventions. An app that ignores both produces an experience that feels wrong to everyone.

React Native's correct use is 'write core logic once, render it natively on each platform'. Business logic — API integration, state management, data transformation, routing — is shared. Platform-specific UI patterns are implemented as separate component variants in the design system, switching by platform automatically. The result is an app that feels native on iOS and native on Android, built from a codebase maintained by a single engineering team.

We build React Native apps with platform-specific design systems, Reanimated 3 animations that run at 60fps on the UI thread, and the New Architecture enabled for improved bridge performance. Expo EAS Build handles the CI/CD pipeline for both platforms simultaneously. Over-the-air updates allow JavaScript-layer fixes to reach users in hours without waiting for a store review cycle.

What You Receive

Exactly What We Deliver

No vague deliverables. Every React Native Development engagement comes with a clear set of files, assets, and outputs.

Cross-Platform Codebase

A fully structured React Native codebase with platform-specific UI variants, shared business logic, and documented component architecture. The codebase follows consistent naming conventions and is organised for long-term maintainability by your engineering team.

EAS Build & OTA Pipeline

Configured Expo EAS Build pipeline producing signed iOS and Android binaries for TestFlight and Play Store distribution. Over-the-air update channels are configured for staging and production environments with rollback capability.

Performance Optimisation Report

A documented performance audit covering JS bundle size, render performance on low-end devices, list scroll frame rates, and startup time. Optimisations applied during the build are recorded with before-and-after measurements.

Native Module Integrations

Any required native module bridges — for device APIs not covered by Expo's managed workflow — are implemented, documented, and tested on both platforms. Bridge code follows React Native's New Architecture patterns for long-term compatibility.

Detox E2E Test Suite

End-to-end tests for critical user journeys — onboarding, authentication, core feature flows, and payment where applicable — running on both iOS simulator and Android emulator. Tests are integrated into the CI pipeline and run on every release build.

Dual Store Submissions

Complete App Store and Google Play submissions for both platforms with platform-appropriate screenshots, descriptions, and review compliance. We manage both review processes simultaneously and respond to any review feedback within the project scope.

Our Process

From Kickoff to Results in 4 Steps

A clear, structured process so you always know where things stand — no guessing, no surprises along the way.

Platform Strategy & Architecture

We assess your feature requirements against React Native's capabilities, decide between CLI and Expo workflows, and design the state management and navigation architecture before building.

Design System & UI

A shared design system is built in Figma with platform-specific component variants so the app feels native on both iOS and Android, not like a compromise between the two.

Build & Integrate

Development proceeds with continuous delivery to TestFlight and Google Play internal track so both platforms are testable throughout the build, not just at the end.

OTA Updates & Launch

EAS Build handles app store submissions. Over-the-air updates are configured for JavaScript-layer changes — allowing bug fixes and minor feature updates to deploy without a full store review cycle.

Common Situations We Fix

Problems We've Seen — and How We Prevent Them

These are real situations that come up. Here's how our process makes each one impossible.

React Native app is slow and animations stutter

Animation jank in React Native is almost always caused by animations running on the JavaScript thread rather than the UI thread. We audit the animation implementation and migrate to Reanimated 3 worklets that execute entirely on the native UI thread — producing true 60fps animations that are immune to JavaScript garbage collection pauses and heavy render cycles.

The app looks and feels the same on iOS and Android — wrong on both

We implement a platform-adaptive design system with separate component variants for iOS and Android UI conventions — navigation patterns, button placement, bottom sheet behaviour, and typography scaling. Platform detection switches the correct variant automatically, producing an experience that follows the conventions users expect on each platform without duplicating business logic.

Deploying a bug fix takes a week waiting for App Store review

Expo EAS over-the-air updates push JavaScript-layer fixes to all users within minutes of deployment, bypassing the App Store review cycle for qualifying changes. We configure the OTA update policy during the initial build so critical fixes can be deployed immediately to production — reducing the mean time to resolution for JavaScript-layer bugs from days to hours.

Web developers struggle to maintain the React Native codebase

We structure the React Native project to maximise overlap with React web patterns — shared hooks, identical API integration approach, the same state management library used in the web product. Platform-specific code is isolated in clearly labelled component variants and platform files. Web developers contributing to mobile features encounter only the mobile-specific differences, not a completely foreign codebase.

Why It Works

What Makes Our Approach Different

We don't just deliver a project — we make sure it actually performs for your business after launch.

Both Platforms for Less Than Two Native Apps

A shared React Native codebase can significantly reduce cross-platform development cost compared to building separate native iOS and Android apps. For startups and growing businesses, this means getting both platforms to market at a cost that previously only bought one.

Faster Updates Across Both Platforms Simultaneously

A bug fix or UI change deployed in a single commit reaches iOS and Android users at the same time. Over-the-air updates via Expo EAS push JavaScript changes without a store review cycle — so critical fixes reach users in hours, not days.

Leverage Your Existing JavaScript Team

If your engineering team already writes React for your web product, React Native requires minimal ramp-up. The component model, state management patterns, and API integration approaches carry over directly — reducing hiring complexity and allowing web developers to contribute to mobile feature development.

Native Performance Where It Matters

React Native's New Architecture — Fabric and JSI — renders UI components through the same native primitives as Swift and Kotlin apps, not a WebView. For most business application use cases, the result is indistinguishable from a native app in terms of scroll performance and animation.
