React Native vs Flutter: Which Should Your Business App Use?

For most business apps, React Native and Flutter are both good enough, and the framework matters less than the team building the app. React Native suits teams that already work in JavaScript and React, and it is the more widely advertised skill in the UK. Flutter suits products with a custom interface that must look identical on iOS and Android. Native Swift and Kotlin apps win only when the product depends on one platform’s hardware or features.

This article compares React Native vs Flutter the way a buyer would, on cost, hiring, performance, web reuse and upkeep, with UK job-market figures from ITJobsWatch. Our own published example, Adinkra, is a React Native build, so weigh our view with that in mind. The framework is one decision inside an app build, which starts from £15,000, and it is rarely the decision that sets the price.

Key takeaways

• React Native and Flutter both build one app for iOS and Android from a single codebase. React Native is maintained by Meta and uses JavaScript. Flutter is supported by Google and uses Dart.
• The framework rarely sets the price. Scope does, and sharing one codebase across both platforms saves more than choosing between the two.
• In the six months to 23 October 2026, UK adverts citing React Native outnumbered Flutter’s by more than eight to one for permanent roles and more than three to one for contracts. Median day rates were similar.
• Flutter’s own documentation says text-rich content such as blog articles suits the document-centric web better, so a marketing website should be an ordinary website either way.
• Choose native Swift or Kotlin only when the product depends on hardware or features specific to one platform.

React Native vs Flutter: what is the difference?

Both frameworks let one team build an app for iOS and Android from a single codebase. They differ in who maintains them, the language you write and how the screens are drawn.

React Native is Meta’s framework. Meta released it in 2015 and has maintained it since, with contributions from individuals and companies around the world (React Native). You write JavaScript with React. Its components render to the platform’s own interface controls, so the app uses the same native platform APIs as any other app.

Flutter is an open-source framework that Google supports and uses. You write Dart, and Flutter’s site says you can deploy from a single codebase to mobile, web, desktop and embedded devices (Flutter). Its documentation says Flutter paints its own interface instead of translating it into the platform’s controls (Flutter docs).

	React Native	Flutter
Backed by	Meta, plus community	Google, plus community
You write	JavaScript with React	Dart
Screens	The platform’s own controls	Painted by Flutter itself
Other targets	Windows, macOS and web, via community projects	Web, desktop and embedded, per its site

Both produce installed apps for the App Store and Google Play. If you are not yet sure an installed app is the right format, our guide to web app vs website vs native app covers that first.

Is React Native or Flutter cheaper to build and run?

Usually neither. Scope sets the price of an app far more than the framework does. Features, integrations, design depth and the backend decide the number, as our guide to app cost in the UK explains. The bigger saving comes from building one cross-platform codebase instead of two native apps, which both frameworks offer.

Build cost

One of our projects shows the size of that saving. Adinkra is a React Native app for iOS and Android, built for Aflé Bijoux. The development phase took under a month, at roughly half the cost of building separately for each platform. That compares one codebase with two, so it says nothing about React Native against Flutter. It is also a single small app.

Our own app build starts from £15,000 whether it is iOS, Android or cross-platform, and the final figure depends on scope. App design and validation starts from £5,000 and takes two to four weeks.

Developer rates are close too. Advertised UK contract rates had a median of £500 for React Native and £494 for Flutter in the six months to 23 October 2026 (ITJobsWatch, below). With day rates that close, any cost difference comes from how many days the work takes and how easily you can find people.

Upkeep after launch

Neither framework removes upkeep. Both keep releasing and phone operating systems keep changing, so a live app needs updates for as long as it runs.

React Native publishes a support policy. It gives the latest stable release the most attention, continues to maintain the previous two minor versions, and says no new releases should be expected for an unsupported version. It recommends that codebases on an unsupported version upgrade as soon as possible (React Native releases). Planned upgrades are therefore part of owning a React Native app.

Flutter’s documentation says Impeller ships inside each app. That lets a developer pick up the latest performance improvements by updating the app, even if the phone has not had a new Android version (Flutter docs). It does not remove the upgrade work either, since the app itself still has to be rebuilt and released.

Plan the upkeep as a running cost whichever you choose. Our ongoing maintenance and support starts from £400 a month.

Which is easier to hire for in the UK?

React Native is the more widely advertised skill in the UK, by a wide margin. ITJobsWatch counts the job adverts that cite a skill. In the six months to 23 October 2026 it found 192 permanent adverts citing React Native against 23 citing Flutter, and 77 contract adverts against 23.

UK, 6 months to 23 Oct 2026	React Native	Flutter
Permanent adverts citing it	192	23
Median permanent salary	£90,000 (137 quoted)	£75,000 (13 quoted)
Contract adverts citing it	77	23
Median contract day rate	£500 (55 quoted)	£494 (20 quoted)

Read the table with three cautions. The figures count job adverts, so they measure employer demand rather than the supply of people. Adverts can cite more than one skill, so the two counts overlap. Flutter’s salary figure rests on 13 quoted salaries, too few to read much into.

The counts also move from year to year. React Native permanent adverts were 137 in the same period of 2025 and 244 in 2024, and Flutter’s were 41 and 53.

If you plan to build an in-house team, the wider market for React Native points to more people with the skill, although adverts cannot prove it. If a supplier builds and maintains the app, you are choosing a team rather than a framework. Our guide to hiring an app developer compares freelancer, agency and in-house routes, with employer costs.

Is Flutter faster than React Native?

In our view, both run a typical business app well. We quote no benchmark numbers, because a test app says little about a booking, payments or content app.

The design of each framework is better evidence than a speed contest. React Native’s documentation says its New Architecture removes the asynchronous bridge between JavaScript and native code and replaces it with the JavaScript Interface (JSI). It has been enabled by default in all React Native projects since version 0.76 (React Native). Any comparison that predates it describes an older design, so check the date on what you read.

Flutter compiles release builds directly to machine code and renders with Impeller (Flutter docs). Because Flutter paints its own interface, a custom design looks the same on both platforms, and animation-heavy or graphics-heavy screens are a natural fit. Because React Native renders to the platform’s own controls, its screens feel like the rest of the phone.

That is the practical difference to choose on. If the product is built around a distinctive custom interface, Flutter’s approach fits. If it is made of standard forms, lists and screens that should behave like the platform’s own, React Native’s approach fits.

Can you reuse the code for a website?

Partly, with limits worth knowing before you plan around it. Flutter’s documentation says its web support suits complex standalone web apps that are rich in graphics and interactive content, and gives existing Flutter mobile apps a browser-based delivery model. It also says text-rich, flow-based, static content such as blog articles suits the document-centric web better than a UI framework like Flutter (Flutter docs).

React Native reaches the web through community projects, and its site names React Native Web among them (React Native).

In both cases the useful split is the same. An app-like product, with logins and interactive screens, can share work between mobile and browser. A marketing site or a blog is better built as an ordinary website.

Some products need all three surfaces. Connect by CoCentric runs on iOS, Android and the web, with team chat, voice and video. Deciding early which surfaces share code, and which are built separately, is part of scoping the project.

When is a native app the better call?

A native app is written separately for each platform, usually in Swift for iOS (Apple) and Kotlin for Android (Android Developers). That means two codebases to build and maintain, so it needs a reason.

The reason is usually hardware or a platform-specific feature that the product is built around. NicheCom, a prototype we built for property surveyors, is a native iPad app because it works with laser-measuring hardware. It remains a prototype, not a live product.

Choosing a cross-platform framework does not lock you out of the platform. React Native’s site says its apps use the same native platform APIs as other apps. Flutter documents platform view widgets, AndroidView and UiKitView, for embedding native content (Flutter docs). A product with one or two hardware-heavy screens can still use a framework for the rest.

How to choose between React Native and Flutter

Start with who will build and maintain the app, then the interface you need. The table maps common situations to a starting point.

If this is true	Lean towards	Why
Your team already writes JavaScript and React	React Native	Same language and ideas as the web
You plan to hire in-house in the UK	React Native	Far more UK adverts cite it
One custom design must look identical on both platforms	Flutter	It paints its own interface
You want screens that feel like the phone’s own	React Native	It uses the platform’s controls
The product depends on one platform’s hardware	Native	Built for that platform alone
You need a marketing site or a blog	Neither	Build an ordinary website

If no row settles it, the framework is not the risky decision. A team that has shipped apps to both stores and a scope you can afford matter more. Our guide to how to choose an app development company lists what to check.

What to do next

Write down the platforms you need, the three things a user does in the app and who will maintain it after launch. With those, a framework choice usually takes a conversation rather than weeks of research.

If you are not sure an app is the right format at all, a one-to-two-week discovery sprint from £4,000 settles that first (product discovery). If you want the app tested before you fund the build, app design and validation takes two to four weeks and starts from £5,000. The build itself starts from £15,000.

Scope and price are fixed and agreed before work starts, you pay as each stage is delivered, and all code and IP are yours once the work is delivered and paid for. On a build, you can cancel within the first 21 days and get your money back in full.

Tell us what you are building and we will say which approach we would use, including native or a web app if that fits better.
