App-Entwicklung: Cross-Platform Development

Cross-PlatformDevelopment

Developing iOS and Android as separate native apps costs twice as much — double the team, double the code, double the maintenance effort. With cross-platform development based on Flutter or React Native you deliver a high-quality, native-feeling experience to users on both platforms from a single shared codebase. This saves budget, accelerates launch and simplifies long-term development without compromising quality or performance.

Build Once for Both Platforms

Challenges you'll recognise

You need to serve iOS and Android simultaneously but don't have the budget for two separate native development teams.
Your iOS and Android apps were developed separately and have diverged in features over time — users on one platform have been complaining about missing functionality for months.
You're unsure whether a cross-platform app can deliver the same quality as two native apps for your product — and you don't know how to evaluate that.

Services in detail

Good to know

Flutter vs. React Native
Flutter renders all UI elements in its own engine, independent of native components — delivering visually consistent results across platforms. React Native uses actual native components instead, making it a natural fit for teams already working in the JavaScript/TypeScript ecosystem.
Shared codebase, platform-specific details
Cross-platform development does not mean everything is identical. Platform-specific differences — such as navigation patterns, permission dialogs, or haptics — are deliberately handled per platform so the app feels like an iOS app on iOS and an Android app on Android.
Maintenance halves
The greatest long-term advantage of cross-platform development lies in maintenance: security patches, feature updates, and OS compatibility adjustments only need to be implemented once and tested once — not separately for each platform.

Frequently asked questions

When does cross-platform development make sense and when should I go native?

Cross-platform makes sense when you want to reach both platforms quickly with a limited budget and have no extreme platform-specific requirements. Native pays off when your app is deeply integrated with hardware features (AR, Bluetooth, complex camera use) or you need maximum performance for graphics-intensive applications. We help you make this decision based on your concrete requirements.

Does a cross-platform app look as good as a native app?

With modern frameworks like Flutter — yes. Flutter renders all UI elements itself, independent of the native UI framework, achieving visual quality that is barely distinguishable from native apps. React Native uses real native components, further strengthening platform conformity. Careful design and platform-specific adaptations are the decisive factor.

Can cross-platform apps access all native device features?

Most of them — yes. Camera, GPS, push notifications, biometric authentication, Bluetooth and in-app purchases are accessible through well-maintained packages for both Flutter and React Native. For very specific or new hardware features we write custom native modules that integrate seamlessly into the cross-platform app.

What does a cross-platform app cost compared to two native apps?

Typically, the development effort for a cross-platform app is around 60-70% compared to two separate native apps. The exact difference depends on scope: the more platform-specific features are required, the closer the effort approaches that of native development. We estimate the effort for both options before you decide.

How are updates deployed simultaneously on iOS and Android?

With a shared codebase we develop and test an update once and submit it to both stores simultaneously. Apple and Google review times may differ, but development and quality assurance run in parallel. This saves time, reduces coordination overhead and prevents iOS and Android users from permanently having different feature states.
