React Native vs Flutter vs native: which should you choose?

Every app needs to run on iOS, Android, or both, and there are three common ways to get there. None of them is universally better. The right choice depends on your app, your budget, and your timeline, not on which technology is trending this year.

React Native: one codebase, two platforms

React Native lets a team write one codebase that runs as a real, native app on both iOS and Android. It is the most widely used cross-platform framework, backed by Meta and used by apps like Instagram and Shopify. For most apps, an ecommerce app, a booking platform, a content app, a fintech dashboard, this is the fastest and most cost-effective path to a native-feeling app on both platforms at once.

The trade-off is that a small number of very platform-specific features (deep hardware integration, certain background processing, some AR features) may need a native module written specifically for that platform. In practice this affects a small minority of apps.

Flutter: Google's alternative, similar trade-offs

Flutter takes a similar approach to React Native, one codebase for both platforms, but uses its own rendering engine instead of each platform's native UI components. This gives Flutter apps very consistent visuals across iOS and Android, which is a strength for highly custom, design-heavy interfaces. The trade-off is that Flutter apps can feel slightly less “native” in how they integrate with each platform's own conventions, and the pool of available developers is smaller than for React Native or native development.

Fully native: Swift and Kotlin

Building separately for iOS (in Swift) and Android (in Kotlin) gives you full access to every platform feature the moment it ships, and the deepest possible integration with each operating system. This is the right choice when an app depends heavily on things like Live Activities, complex widgets, ARKit, or background processing that pushes the limits of what the platform allows. The cost is real: building and maintaining two separate codebases roughly doubles the ongoing development and testing effort compared to a single cross-platform codebase.

How to actually decide

Ask three questions about your idea:

• Does it depend on deep platform-specific features? If yes, especially on iOS, native development is often worth the extra cost. If no, cross-platform is almost always the better starting point.
• What is the budget and timeline? Cross-platform frameworks reach both app stores faster and cheaper. If budget or speed to market is a real constraint, this usually settles the question.
• Will the team need to maintain it for years? One codebase is simpler to maintain, test, and hand over to a new team later than two. This matters more than it seems at the start of a project.

In our experience building and shipping our own apps, React Native covers the large majority of real-world app ideas well, which is why it is our default recommendation unless a project has a specific, concrete reason to go native. The technology is a means to an end. What actually matters is whether the app works well, launches on time, and stays affordable to maintain.
