Cross-Platform Apps

You don't always need two separate teams to build for iOS and Android. Modern cross-platform frameworks let us build high-performance, native-feeling apps that run on both platforms from a single codebase. It's faster to build, easier to maintain and better for your budget.

When Cross-Platform Makes Sense

Cross-platform development has come a long way. With Flutter and React Native, we can build applications that are indistinguishable from native ones. We share up to 90% of the code between iOS and Android, which means your features ship faster and your maintenance costs are cut in half. Whether you're a startup looking to hit both stores quickly or an enterprise needing a consistent internal tool, cross-platform is often the smartest choice.

  • You need to launch on iOS and Android simultaneously
  • Your app is primarily data-driven rather than hardware-heavy
  • Budget or timeline makes maintaining two native codebases impractical
  • You want a single engineering team that understands the whole product
  • You're building an MVP and need to validate quickly across both platforms

When to Choose Native Instead

We'll always give you an honest recommendation. Cross-platform isn't right when your app relies heavily on cutting-edge platform-specific features, when you need the absolute maximum performance (like a high-end game or intensive AR experience), or when your app deeply integrates with hardware in ways React Native doesn't support well.

How We Build Cross-Platform Apps

React Native Done Properly

We've seen the React Native anti-patterns — web views masquerading as native screens, ignored platform conventions, poor performance from JavaScript thread bottlenecks. We avoid all of them. Our React Native apps use proper navigation patterns, follow iOS and Android UX conventions separately, and optimise performance using native modules where needed.

Platform-Specific UX

A good cross-platform app doesn't look identical on iOS and Android. We apply platform-specific design patterns — iOS navigation on iOS, Material Design principles on Android — so users on each platform feel at home.

Native Modules

When React Native's JavaScript bridge isn't fast enough for a specific feature, we write native modules in Swift or Kotlin and expose them to the React Native layer. You get the benefits of a shared codebase without sacrificing performance where it matters.

Frequently Asked Questions

Clear answers to common questions about cross-platform development.

Is React Native as good as native development?

For most apps, yes. The performance gap between React Native and native has narrowed significantly with the new architecture. The apps we build in React Native are indistinguishable from native for the vast majority of use cases.

Can you add React Native to an existing native app?

Yes — this is called a brownfield integration. We've done it for clients who wanted to add new screens to an existing native app without rewriting it. It requires careful architecture but works well.

What about Flutter — do you build in Flutter?

Our primary cross-platform expertise is React Native. We can discuss Flutter for your specific project, but React Native is where our deepest experience lies.
