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.
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.
| Detail | |
|---|---|
| Maintainer | Meta and the open-source community |
| Language | JavaScript / TypeScript |

| Tooling | Expo, React Native CLI |
| Best for | Business, commerce and SaaS companion apps |
| Watch-outs | Keep versions and dependencies current |
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.
| 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?

- 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.
| 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.
| 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.
