Both Flutter and React Native are mature, production-proven ways to build one app for iOS and Android. Choose Flutter when you want a highly custom, pixel-consistent UI across platforms and one codebase that can also target web and desktop. Choose React Native when your team already works in React and TypeScript, or you want the app to use each platform's native UI components.
Disclosure: Anekant Tech builds most of its mobile apps in Flutter. We've tried to keep this comparison fair; both frameworks are good choices for most business apps.
How each framework works
Flutter, created by Google, uses the Dart language and draws every pixel of the interface itself with its own rendering engine (Impeller). Your app looks the same on iOS and Android because Flutter doesn't rely on the platform's built-in UI components.
React Native, created by Meta, uses JavaScript or TypeScript and React. It renders real native iOS and Android components. Its New Architecture (Fabric and JSI) is now the default and removed much of the old communication overhead between JavaScript and native code.
Side-by-side comparison
| Factor | Flutter | React Native |
|---|---|---|
| Language | Dart | JavaScript / TypeScript |
| UI approach | Own rendering engine; identical UI on every platform | Native platform components |
| Custom, animated UI | Excellent, full control of every pixel | Very good, often with extra libraries |
| Native look and feel | Provided by Material and Cupertino widgets | Automatic, because components are native |
| Web and desktop | Official support for web, Windows, macOS and Linux | Web via React Native Web; desktop via community projects |
| Hiring pool | Smaller but growing | Large, thanks to the React ecosystem |
| Code sharing with a React website | Limited | Strong (logic, types, sometimes components) |
| Over-the-air updates | Via third-party services | Mature options such as Expo EAS Update |
Performance
For typical business apps (forms, lists, dashboards, maps, payments) users won't notice a performance difference between a well-built Flutter app and a well-built React Native app. Flutter has an edge for heavy custom animation and graphics because it controls the whole rendering pipeline. In both frameworks, the quality of the engineering matters far more than the framework.
When Flutter is the better choice
- Your brand needs a distinctive, highly animated UI that must look identical everywhere.
- You want one codebase for mobile, plus a web or desktop app later.
- You're starting fresh with no existing React investment.
- You need consistent rendering on low-cost Android devices.
When React Native is the better choice
- Your team or agency already works in React and TypeScript.
- You want to share business logic and types with a React or Next.js website.
- You want each platform's native components and behaviour by default.
- Over-the-air updates for quick fixes are important to you.
Questions to ask before you decide
- Who will maintain the app in three years, and what do they know today?
- How custom is the design: standard platform UI or a strong brand look?
- Do you need web or desktop versions from the same codebase?
- Which native features (Bluetooth, NFC, background location) are critical, and do mature plugins exist for them?
