Choose React Native if your team already works with JavaScript and React, or if your app needs to share code with a web front end. Choose Flutter if you want top performance, smooth animations and one identical look across all platforms. React Native has a larger ecosystem and ties into web knowledge. Flutter delivers better performance and pixel-perfect consistency because it does its own rendering. For most companies the available team is the decisive factor: build with the language your developers already know.
React Native and Flutter are both mature frameworks for building one codebase for iOS and Android. The choice between the two is rarely about which is "better", and almost always about which team you have and what your app needs to do. Below is the honest comparison.
React Native uses JavaScript and React, and bridges to the real native components of the operating system. Flutter uses Dart and draws every pixel itself through its own rendering engine. That difference explains most of the pros and cons.
For most business apps both perform more than well enough. The difference becomes noticeable with graphically heavy apps, complex animations or lots of simultaneous interaction.
Flutter wins on raw UI performance and animations. React Native wins on integration with existing native code and on sharing logic with your website.
If you have an app with lots of animation, a game-like interface or heavy visualizations, Flutter gives an edge. If you build an app around forms, lists, accounts and API calls, you will barely notice the difference in practice.
For most companies this is the decisive factor.
At NedDev we work primarily in the React world with Next.js 16 and React 19. For clients who already have a web product with us, React Native is often the logical choice: shared knowledge, shared components, one team that understands everything.
Choosing a framework your team does not master means either hiring or paying a learning curve. For an SMB that weighs heavier than a few percent of performance difference. The cheapest app is usually the one in the language your developers already know.
Sometimes a cross-platform app is not even the right solution.
Many clients who want "an app" actually need a good mobile web experience. That can save tens of thousands of euros. We always discuss that trade-off before we build.
Run through these questions:
Building a mobile app costs between €18,000 and €70,000, depending on complexity and the number of platforms. The framework choice affects that, but your team and scope decide most. Look at our app development approach, or let us think along about whether you need an app at all.
The build cost is just the beginning. An app is software that moves along with two operating systems that change every year. Both frameworks have their own profile here.
For both, count on ongoing maintenance: an app you do not touch for a year falls behind the latest iOS and Android versions and can even drop out of the store. Budget maintenance from the start, it is not an option but a requirement.
For by far the most business apps, built around accounts, lists, forms and backend integrations, both frameworks perform more than well enough and the difference in end result is small. The deciding factor is practical: which team you have, whether you share code with a website, and who maintains the app in two years. Start there, not at a benchmark. The right choice is the one your organization can carry.
On raw UI performance and animations, yes. Flutter draws every pixel itself through its own rendering engine, which gives smooth, consistent interfaces. For most business apps around forms, lists and API calls you barely notice the difference in practice. React Native wins instead on integration with existing native code and web knowledge.
Then React Native is often the logical choice. It builds on JavaScript and React, the same basis as your website, so your team can jump straight in and you can share logic and components. You avoid the learning curve of Dart, the language of Flutter, and keep everything in one familiar ecosystem.
Many companies that want "an app" actually need a good mobile web experience. A PWA is an installable website without an app store, cheaper and faster to update. If you have no heavy hardware integration or strict performance demands, a PWA often saves tens of thousands of euros. We always discuss that trade-off before we build.
