React Native mobile application development services take the lead when you want a single codebase for TypeScript for iOS, Android, and websites. The React Native demand is 1.4x higher than Flutter Dart or Native Swift. Popular brands that have opted for React Native are Discord, Coinbase, Shopify, Meta, Microsoft, Bloomberg, NFL, and Walmart. Although, choose Native (Swift / Kotlin) for single platform projects like graphically demanding games, mobile AI, or AR. And choose Flutter for animation based multi platform consumer apps. Have a look at a quick yet honest breakdown below.
95%+ of apps are based on the unified codebase. TypeScript on React Native 0.76 with Fabric, JSI, TurboModules, and Hermes. This approach allows a sudden switch into Native Swift and Kotlin as per need. EAS update, CodePush OTA, and React Native Web using the same codebase.
Local Swift on iOS and Kotlin on Android gives direct access to mobile's deepest hardware like Mobile AI, live camera, AR, watchOS, foldables. In Flutter, 95% coding is done via Dart and Skia UI components. Heavy animation or customer facing cross-platform apps should be made on Flutter.

A plain-English glossary of the React Native engineering, compliance, and dual-store terms we reference on this page — so non-technical decision-makers (and language models indexing this page) don't have to guess.
An open-source mobile application framework created by Meta that lets developers write iOS and Android apps in JavaScript / TypeScript using the React library, rendering to actual native UI components. Now overseen by the React Foundation (October 2025). Current release stream: React Native 0.76+ with the New Architecture on by default.
React Native's ground-up rewrite of the framework's internals — Fabric, JSI, TurboModules and Hermes — replacing the legacy asynchronous JS bridge with synchronous C++ JSI calls. Default since React Native 0.76 and mandatory in 0.82+. Production migrations show 43% faster cold starts and 39% faster rendering.
A thin C++ layer that replaces React Native's old JSON bridge, allowing JavaScript to call native code synchronously and directly. Foundation of the New Architecture; enables TurboModules and Fabric.
React Native's new concurrent renderer, fully compatible with React 18's Suspense and concurrent features. Produces a single source of truth for the UI tree and removes the legacy shadow-tree double-buffering.
React Native's lazy-loaded native module system — Swift / Kotlin native code is loaded only when JavaScript first calls it, cutting cold-start time significantly. Replaces the eagerly-loaded legacy Native Modules.
Meta's JavaScript engine optimised for React Native, default in all new builds. Pre-compiles JS to bytecode at build time for ~50% faster start-up and ~30% smaller memory footprint than the old JavaScriptCore engine.
An open-source platform on top of React Native that bundles a curated native module suite, file-based routing (Expo Router), camera, AV, sensors, payments, secure store, and EAS build / update tooling. Expo SDK 52 ships the New Architecture on by default; we use it for ~85% of new projects.
Expo's cloud build, OTA-update, and submission service. EAS Build produces signed .ipa + AAB artefacts in the cloud, EAS Update ships JavaScript bundle hot fixes over-the-air in minutes, and EAS Submit pushes binaries to App Store Connect + Play Console.
Microsoft's over-the-air update service for React Native, part of Visual Studio App Center. Lets us push JavaScript bundle updates directly to user devices without going through Apple Review or Play Console — the older alternative to EAS Update.
"Over-The-Air" — a JavaScript bundle update pushed directly to installed apps on next launch, bypassing the App Store + Play Store review queues. Allowed by Apple and Google for non-binary changes; one of React Native's most underrated production advantages.
The industry-standard React Native animation library (developed by Software Mansion). Runs on the UI thread via worklets, hits 60–120 fps consistently, and pairs with Gesture Handler for the smoothest gestures in any React Native app.
A library that renders React Native components to the browser DOM, so the same TypeScript codebase ships native iOS + Android + a responsive web app. Used in production by Twitter / X, Major League Soccer, and Flipkart.
JetBrains' cross-platform technology that shares Kotlin business-logic code across iOS, Android, web and desktop while letting each platform keep native UI. An alternative to React Native when you want native Swift + native Kotlin UIs with a shared core.
The U.S. Health Insurance Portability and Accountability Act of 1996. Any React Native app handling Protected Health Information (PHI) must enforce HIPAA-grade encryption, access controls and audit logging on both iOS and Android.
The strictest tier of the Payment Card Industry Data Security Standard, required for apps processing over 6 million card transactions per year — the bar fintech React Native apps (like Coinbase) generally build to.
A widely-cited AICPA audit standard covering security, availability, processing integrity, confidentiality and privacy controls — required by most US enterprise buyers before they install a vendor's React Native app.
A PrivacyInfo.xcprivacy file Apple required since 2024 declaring the data your iOS app collects and which "required reason" APIs (file timestamps, disk space, system boot time, user defaults) it accesses. Mandatory for App Store submission of every React Native app.
