Why We Build All Our Mobile Apps with React Native

Every client building a mobile app asks the same question: native or cross-platform? After shipping over 40 apps across fintech, health, e-commerce, and logistics — I have a clear answer: React Native, with native for edge cases. Here's exactly why.

The State of React Native in 2025

React Native has matured enormously since its early days of performance complaints and the "bridge" bottleneck. The New Architecture (Fabric + TurboModules + JSI) — now the default since RN 0.74 — eliminates the asynchronous bridge entirely, enabling synchronous communication between JavaScript and native code. The result: buttery 60fps animations, sub-100ms response times, and a development experience that's genuinely excellent.

The Commercial Case

• <strong>~50% lower development cost.</strong> One team, one codebase, two app stores. For a typical £60K native dual-platform project, React Native brings this to ~£35K.
• <strong>Shared code with your web team.</strong> If you already have React developers, they can contribute to the mobile app immediately.
• <strong>Faster iteration.</strong> Hot reload + single codebase means bug fixes and features ship to both platforms simultaneously.
• <strong>Expo ecosystem.</strong> Expo's managed workflow handles builds, OTA updates, and app store submissions — eliminating most DevOps overhead.
• <strong>Meta's backing.</strong> React Native is used in production by Meta, Microsoft, Shopify, and Coinbase. It's not going anywhere.

Where React Native Excels

React Native is the right choice for: CRUD-heavy business applications, e-commerce apps, fintech apps (payments, dashboards), social apps, content consumption apps, and any app where the primary interface is forms, lists, and screens. The UI/UX parity with native apps is now indistinguishable to end users for 95% of use cases.

import { useCallback } from 'react';
import { FlatList, StyleSheet } from 'react-native';
import { useProducts } from '../hooks/useProducts';
import { ProductCard } from '../components/ProductCard';

export function ProductScreen() {
  const { products, isLoading, fetchMore } = useProducts();

  const renderItem = useCallback(
    ({ item }) => <ProductCard product={item} />,
    []
  );

  return (
    <FlatList
      data={products}
      renderItem={renderItem}
      onEndReached={fetchMore}
      onEndReachedThreshold={0.5}
      removeClippedSubviews
    />
  );
}

When to Choose Native Instead

Native iOS or Android makes sense when you need: ARKit/ARCore with frame-level access, real-time audio/video processing, complex custom animations that depend on native gesture recognisers, deep OS integration (widgets, custom keyboards, Watch apps), or when performance profiling shows React Native genuinely can't hit your targets (rare, but possible for game-like UIs).
