React Native App Development Company: React Native Application Development Services

Updated September 2026 · Written and maintained by the Progression Agency strategy team

React Native lets one team build real iPhone and Android apps with React and TypeScript. Progression Agency is a React Native development company that builds, publishes and maintains React Native apps for businesses across the US and worldwide: from new products and MVPs to companion apps for existing web platforms and migrations from separate native codebases.

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.

How does React Native work on iOS and Android?

How does React Native work? Your React code runs in a JavaScript engine, and React Native turns it into real platform views, UIKit views on iOS and Android Views on Android, instead of a web page inside an app shell. In the New Architecture, a JavaScript Interface lets JavaScript call native code directly without the old asynchronous bridge. That is why React Native iOS and Android apps can share most logic and interface code while still using each platform’s own controls. React Native cross platform development works best when you plan for the places the platforms differ, such as permissions, navigation gestures and push notifications.

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.

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. What is Expo React Native? The React Native documentation describes Expo as a production-grade framework with tooling such as file-based routing and a standard library of native modules, and it recommends starting new apps with a framework. Your React Native development environment then needs little beyond Node.js and a phone or simulator; the official setup guide walks through 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 price band, 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.

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.

React Native app development services, agency and company: how to compare

Searching for a React Native app development service, a React Native app development agency or a React Native mobile app development company usually means you are comparing the same few things. Ask who writes the code, whether the team has released React Native apps in both app stores, and how they handle native modules when a library falls short. React Native mobile app development services should include release, crash reporting and upgrades after launch. If you are also weighing a native mobile app development company, ask for the trade-offs on cost, speed and device features in writing. A React Native development agency should show shipped apps on both stores; when you compare React Native development agencies, ask who writes the native modules and who maintains the upgrades.

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.

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.

Our default

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