React Native vs Flutter: a buyer's view

From a buyer's seat, React Native and Flutter are both sound choices, and the technical gap between them matters less than three practical questions: will you be able to hire people or find a vendor to take over the code, will the app fit with your existing tools, and do you actually need a mobile app rather than an installable web app? React Native runs on JavaScript and TypeScript, which most developers know; Flutter runs on Dart, less common but consistent from end to end.

This article does not settle a developer debate. It gives the criteria a founder, an operations lead or a project owner can check before signing off on the framework a vendor proposes.

Two frameworks, two philosophies

Both tools solve the same problem: one codebase for iPhone and Android instead of two separate native apps.

React Native was released by Meta in 2015 and is still maintained by it. Apps are written in JavaScript or TypeScript with React. According to the official site, it is "written in JavaScript, rendered with native code": a React Native button is a real iOS or Android button. Meta and Microsoft (Office, Outlook, Teams) use it in production, along with many consumer apps. The documentation now recommends starting with a framework such as Expo, which supplies navigation, hardware access and release tooling.

Flutter is backed by Google and written in Dart. Its architectural overview explains that Flutter has its own implementation of every UI control rather than using the system's, and that release builds compile to machine code. Flutter also targets the web and desktop (Windows, macOS, Linux).

In practice, a React Native app naturally looks like an iOS app on an iPhone and like an Android app on Android, while a Flutter app looks the same everywhere, which suits brands that want pixel-identical screens on every device.

Side by side, from the buyer's seat

None of these rows is a deal breaker. The right choice depends on your context: the team you already have, your existing tools, how much visual consistency matters, and how long the app should live.

Hiring and handover

This is the criterion that weighs most over the years, and the one a buyer can assess without a technical background.

In the 2025 Stack Overflow Developer Survey, 66% of respondents said they use JavaScript and 43.6% TypeScript, against 5.9% for Dart (worldwide, self-reported). The 2024 edition, the latest to break out mobile frameworks, had the two neck and neck among professional developers: 9.4% for Flutter and 9% for React Native.

Two things follow. The frameworks themselves see comparable use. The language behind React Native, however, is the language of most web development: a React web developer becomes productive in React Native faster than someone new to Dart becomes productive in Flutter. For a small or mid-sized company, that means more candidates and more vendors able to take over the code when you change teams.

Flutter keeps a strong argument of its own: everything, from interface to logic, is written in one language with one toolset, which makes projects consistent and easy to read for anyone who knows Dart. The handover risk is then managed through documentation and the contract, as with any software. Our guide to avoiding vendor lock-in lists what you should be able to take with you.

Perceived performance

Benchmarks get shared a lot and matter little for a business app. Both frameworks have improved markedly:

• React Native made its New Architecture the default in version 0.76, in October 2024, cutting the overhead of communication between JavaScript and native code;
• Flutter now renders with Impeller, the only engine on iOS and the default on Android API 29 and above since release 3.27.

On a recent phone, a data entry, lookup or tracking app will feel smooth with either. What your users will experience as slowness comes from elsewhere: weak signal in the field, cluttered screens, a slow API, badly designed offline sync. That is where to judge a vendor, by asking how they handle those cases, rather than by their framework.

Flutter keeps a real edge for heavily animated or highly customised interfaces, since it draws every pixel itself. React Native keeps its edge on following each platform's conventions, which iPhone users do notice.

Ecosystem and fit with your tools

A business app rarely lives alone: it talks to an admin back office, an ERP, an invoicing tool, a company directory.

React Native benefits from the whole JavaScript ecosystem, and part of the logic (form validation, API calls, data types) can be shared with a React web application. If your back office already runs on React or Next.js, that is a concrete argument for consistency and lower maintenance costs.

Flutter has its own catalogue of packages, rich and well documented, plus strong built-in tooling. It fits well when the mobile app is the main product, with a dedicated team behind it.

Either way, ask for the list of third-party libraries the project will use and how actively they are maintained: an abandoned library is a future maintenance bill. Our guide to choosing a tech stack for business software offers a broader way to judge a stack.

The real question: do you need a mobile app?

Before choosing between React Native and Flutter, check that the app really has to go through the stores. For many business apps (field data entry, lookups, approvals, tracking), a web app installed on the home screen is enough: one codebase for phone, tablet and desktop, updates without store review, and the same code as the back office.

A mobile app is justified when people must work offline for long periods, use the hardware in depth (Bluetooth, background location, NFC), receive reliable push notifications, or find the app on the App Store and Google Play. Our comparison of web apps, PWAs and native apps covers those criteria, and our guide to mobile app development cost shows what each option adds to the budget.

Questions to ask your vendor

1. Why this framework for this project? A good answer talks about your constraints (team, tools, hardware), not about a preference.
2. Who could take over the code if we change teams? Ask how common that profile is on the market.
3. How does the app behave without a network? That is where perceived quality is won or lost.
4. Which third-party libraries, maintained by whom?
5. Who handles the updates iOS and Android force every year? They arrive whether or not you ask for anything new.

Where to start

At LPR Studio, our technical foundation is the web (React, Next.js, TypeScript): applications that work on desktop, tablet and phone. So the question "does this need to be in the stores?" comes first, before any framework choice and before any price is set. Describe your need and we will present a free visual prototype in a video call within 5 working days, wherever you are, showing how your app would look on each screen. The ways to pay for the build are on our offers page.
