Why cross-platform app development with MaibornWolff is worthwhile

For us, cross-platform app development means more than just a shared code base. We ask the right questions about your requirements and provide you with technology-neutral, expert advice—so that the end result is a solution that is perfectly tailored to your specific context.

Your business first

We work as if we were part of your company: responsibly, proactively, and with clear focus.

Autonomy & responsibility

Our experts independently decide on the right architecture and use GenAI to maximum effect. Close coordination with our customers is a matter of course for us.

Tailor-made quality

No off-the-shelf solutions: We develop software that is as unique as your business model.

Proactive & committed

We think proactively, identify risks early on, and act quickly before problems and unnecessary costs arise.

I am really positively surprised by the cross-platform solution: it works well and runs smoothly. No compromises in terms of security, performance, or stability. The budget is significantly below the planned figure for native development.

Quality check for your app: focus on performance & accessibility

If your cross-platform app is already in use, it's worth taking a closer look at its stability, security, expandability, and user-friendliness. Our App Health Check comprehensively analyzes your application, from security vulnerabilities and stability issues to unnecessary complexity. 

We also check whether your foundation is truly capable of supporting future enhancements. You will receive clear recommendations on how to improve modularity and code quality; we can implement these changes for you upon request. This ensures that your app remains efficient, robust, and future-proof. 

Equally important: accessibility. Since June 2025, B2C apps must meet the requirements of the BFSG. We analyze your app specifically, provide pragmatic advice, and give clear recommendations for implementation. If you commission us, we will of course also take care of this. This ensures that your app reaches everyone and remains legally compliant.

FAQ: Frequently asked questions about cross-platform app development

  • What is the difference between multiplatform and cross-platform?

    Cross-platform refers to the development of an app with a uniform code base for several platforms such as iOS, Android or the web.

    In contrast, multi-platform usually describes the parallel use of different technologies for each platform.

    If required, we can also assist you with our native development expertise.

  • Which language is used for cross-platform app development?

    Frameworks such as Flutter (Dart) or React Native (JavaScript/TypeScript) are used for cross-platform app development. The choice depends on the requirements of your project.
