App-Entwicklung: React Native App Development

React NativeApp Development

React Native combines the best of both worlds: a shared codebase and real native UI components. The result are apps that feel native on iOS and Android, are faster to build and cheaper to maintain than two separate native projects. We develop React Native apps from architecture to store release – with a focus on performance, clean TypeScript code and long-term maintainability.

Start a React Native project

Challenges you'll recognise

You need iOS and Android but have neither the budget nor the team for two separate native developments.
Your existing hybrid app feels like a website in an app shell – users complain about stuttering lists and unnatural interaction.
You want to ship features quickly, but every release means double the effort for two separate codebases.

Services in detail

Good to know

Real native components
React Native does not render a WebView but drives real native UI elements. As a result the app behaves like a native app for scrolling, gestures and animations – a key difference from pure WebView hybrid approaches.
TypeScript as the foundation
We build React Native apps consistently in TypeScript. Static typing catches errors early, keeps the code readable for follow-up teams and significantly reduces regressions during further development.
Over-the-air updates
A major practical advantage: many JavaScript changes can be shipped directly to devices without a renewed store review. Critical fixes therefore reach users considerably faster.

Frequently asked questions

What is the difference between React Native and Flutter?

Both are mature cross-platform frameworks. React Native uses real native UI components and JavaScript/TypeScript – ideal when your team already comes from the React world or when web and app should share common logic. Flutter renders the UI in its own engine and delivers maximum visual consistency. We recommend the framework based on your requirements, not on preference.

Is a React Native app as fast as a native app?

For the vast majority of apps – business apps, marketplaces, social networks, content apps – the performance difference is not noticeable to users when the app is built cleanly. For extremely graphics-intensive applications such as elaborate 3D games or compute-heavy real-time processing, native development can have advantages. We clarify that honestly upfront.

Can I migrate an existing native app to React Native?

Yes, often step by step. React Native can be integrated into an existing native app, so individual screens can be migrated gradually instead of rebuilding everything at once. We analyze your existing app and develop a migration strategy that minimizes risk and effort.

Do large companies use React Native?

Yes. React Native is used in production by numerous well-known apps and is actively developed by Meta and a large open-source community. That means long-term maintenance, a stable ecosystem and a large talent pool – an important factor for the future-proofing of your app.

Do you also handle publishing to the app stores?

Yes. We handle publishing to the Apple App Store and Google Play Store including store listing, review process and technical requirements. The developer accounts run under your name so you always keep full sovereignty over your app.
