What Is React Native, and Is It Right for Your App?
React Native is like a translator at a meeting. Your team speaks one language, JavaScript, and the translator passes each instruction to Android and iPhone in their own native words.
What React Native is
Meta (the company behind Facebook and Instagram) released React Native in 2015. It grew out of React, a very popular tool for building websites. The idea: if web developers already know React, let them build real phone apps with the same skills.
React Native is open source and free. Apps are written in JavaScript or, more often today, TypeScript, a safer version of JavaScript.
How React Native works
This is the key difference from Flutter. Flutter paints its own buttons. React Native instead uses the phone's real, built-in building blocks. When your code says "show a text box", React Native asks iOS for an iOS text box and Android for an Android one.
So apps tend to feel at home on each phone, because they are using the same parts as the phone's own apps.
In recent versions, React Native moved to a rebuilt core called the New Architecture, now on by default. In simple terms, it made the link between JavaScript and the phone faster and more direct, which helps smooth scrolling and quick responses.
Many teams build React Native apps with Expo, a set of tools and services that make setup, testing and app store builds much easier. React Native's own docs recommend starting new apps with a framework like Expo.
What React Native is good for
- Companies with web developers who know React and want to reuse their skills.
- Android and iOS apps on one budget, especially content, social, shopping and service apps.
- Sharing code with a React website, such as business rules and data handling.
- Fast fixes: with the right setup, some JavaScript-only updates can be sent to users without a full app store release, within the stores' rules.
When React Native is not ideal
- Heavy graphics, games or advanced camera work, where native code or a game engine does better.
- Pixel-identical custom design everywhere. Because it uses native parts, small look differences between Android and iOS are normal.
- Many specialist native features. Each one may need native code in Swift or Kotlin, which shrinks the "one codebase" benefit.
- Old, unmaintained libraries: React Native relies on many community add-ons, and some fall behind updates.
React Native vs Flutter
| React Native | Flutter | |
|---|---|---|
| Made by | Meta | |
| Language | JavaScript / TypeScript | Dart |
| How screens are drawn | Uses each phone's native parts | Draws its own parts |
| Look across phones | Matches each platform | Identical everywhere |
| Best team fit | Web / React developers | Mobile-focused teams |
One more practical point: a React Native app and a React website can be built by the same people. If you already pay a web team, that can make React Native the cheaper option to run, even when the build costs look similar on paper.
Both are solid, mainstream choices. The decision usually comes down to your team's existing skills and how custom your design is.
What React Native means for cost and timeline
Like other cross-platform tools, React Native means one codebase and usually one team, which tends to cost less than two native apps. If you already have React web developers, onboarding them can be quick.
Budget for upkeep. React Native and its add-ons update often, and skipping updates for too long can make later upgrades bigger jobs. A small, regular maintenance plan is cheaper than a big catch-up project.

Our default cross-platform choice is Flutter, but we will talk you through React Native honestly if your team already works in React. Either way, you get a fixed-price written quote within 24 hours and full ownership of your code. Start on our app development page, or read the official React Native docs.
Common questions
Is React Native the same as React?
Not quite. React is for building websites. React Native uses the same ideas and much of the same way of writing code, but it builds real Android and iOS apps instead of web pages. Developers who know React can learn React Native fairly quickly.
Is React Native still a good choice?
Yes. It is maintained by Meta and a large community, has been rebuilt for better speed with its New Architecture, and is widely used for production apps. It is a strong pick when your team knows JavaScript or React. Flutter is the main alternative to compare it with.
What is Expo in React Native?
Expo is a set of tools and services built around React Native. It makes it easier to start a project, test on real phones, use device features and create app store builds. Many new React Native apps use Expo from day one.
Can React Native apps be updated without the app store?
Some changes can. Updates that only change JavaScript code can be pushed to users through services like Expo's updates, as long as they follow Apple and Google rules. Changes to native code, or big new features, still need a normal store release.
Is React Native free?
Yes. React Native is open source under a permissive license, so it is free for commercial apps. Optional services around it, such as Expo's cloud build and update services, have free tiers and paid plans.
