The short answerReact Native application development uses Meta’s open-source framework to write a mobile app once in JavaScript or TypeScript and render genuine native interface components on iOS and Android. It suits business, commerce and SaaS companion apps, especially when you already have a React web app. A React Native business app commonly takes 3-5 months and, as a US planning range, costs $60,000-$160,000 for both platforms.

Framework details reflect the React Native and Expo documentation as of September 2026. Cost ranges are planning figures, not quotes.

What is React Native application development?

React Native application development is building mobile apps with React Native, an open-source framework from Meta that uses React components written in JavaScript or TypeScript to render native iOS and Android interface elements from a single codebase.

Unlike a web view wrapped in an app shell, React Native draws real platform controls, so apps feel native. Platform-specific features are reached through native modules written in Swift or Kotlin.

RN — New React Native apps. iOS and Android from one codebase..

MVP — React Native MVPs. Fast route to both stores..

Web — Companion apps. Share logic with a React web app..

Move — Native-to-RN migration. Consolidate two codebases..

Up — Upgrades and rescue. Update stale RN projects..

Mod — Native modules. Camera, Bluetooth, payments..

Mobile app development with React

If your product has a React web app, React Native lets the same team, the same language and much of the same business logic, validation and API code carry over to mobile.

React Native vs Flutter vs native: when to choose React Native

Choose React Native when you have React or TypeScript skills, want to share logic with a web app, or rely on the npm ecosystem. Choose Flutter for highly custom, identical UI; choose native for graphics-heavy or hardware-intensive apps. The full comparison is on our cross-platform app development page.

React Native at a glance
	Detail
Maintainer	Meta and the open-source community
Language	JavaScript / TypeScript
Rendering	Native platform components
Tooling	Expo, React Native CLI
Best for	Business, commerce and SaaS companion apps
Watch-outs	Keep versions and dependencies current

How we build a React Native app — Keeping React Native versions current is the single most important maintenance habit.

Our React Native development services

New React Native apps

Full apps from discovery to both stores, with backend and admin.

Expo and bare workflows

We use Expo for faster builds and over-the-air updates where it fits, and a bare workflow when custom native code demands it.

Native modules

Swift and Kotlin modules for camera pipelines, Bluetooth, payments and platform features React Native does not cover out of the box.

Upgrades and rescue

Stale React Native projects accumulate breaking changes. We upgrade versions, replace abandoned libraries and restore reliable builds.

Migrating native apps to React Native

Two native codebases can be consolidated screen by screen into React Native to cut maintenance cost.

How much does React Native app development cost?

As a US planning range, a React Native MVP commonly costs $40,000-$90,000 and a full business app $90,000-$160,000 for both platforms, typically less than two separate native builds.

React Native cost ranges (planning figures)
Scope	Typical range	Timeline
MVP (iOS + Android)	$40,000-$90,000	10-16 weeks
Business app	$90,000-$160,000	4-6 months
Upgrade / rescue project	$10,000-$40,000	2-6 weeks

Why choose Progression Agency for React Native?

TypeScript-first React Native teams with native module experience.
Honest framework advice — we also build Flutter and native.
Builds on both stores every sprint.
App Store and Google Play launch handled.
You own the code. Headquartered in New York City.

The React Native New Architecture

React Native’s New Architecture became the default in version 0.76. It replaces the old asynchronous bridge with direct, synchronous communication between JavaScript and native code, which improves responsiveness and makes native modules faster to call.

What the New Architecture changes
Component	What it does
JSI (JavaScript Interface)	Lets JavaScript hold references to native objects and call them directly
Fabric	The new rendering system, supporting concurrent React features
TurboModules	Native modules loaded lazily and called without the bridge
Codegen	Generates type-safe glue code between JavaScript and native modules

Details from the React Native architecture documentation. We build new apps on the New Architecture and migrate older apps library by library.

Expo or bare React Native?

The React Native documentation now recommends starting with a framework, and Expo is the most widely used. We choose per project.

Expo vs bare React Native
Factor	Expo	Bare React Native
Setup and builds	Managed cloud builds with EAS Build	Local Xcode and Android Studio builds
Native code	Supported through config plugins and development builds	Full direct control
Over-the-air updates	Built in with EAS Update	Requires a third-party service
Routing	File-based with Expo Router	Choose a navigation library
Best for	Most business and consumer apps	Apps with heavy custom native integrations

Our default

Most projects start on Expo with development builds, which keeps full native access while removing most build maintenance.
