Native app or cross-platform – which is better for my project?

Native apps (Swift/Kotlin) offer maximum performance and access to all device features. Cross-platform solutions (Flutter/React Native) enable faster development for iOS and Android with one codebase and lower costs.

What does a website or app cost?

Depends heavily on scope. A professional website starts at 5,000-10,000 €. Web apps and mobile apps typically range from 20,000-80,000 €. We provide a transparent quote after the requirements analysis.

How long does app development take?

Website: 4-8 weeks. Web app: 2-4 months. Mobile app: 3-6 months. We work agile with regular releases – you see results early.

Can my app also work offline?

Yes, we develop apps with offline functionality that store data locally and automatically synchronize when connected to the internet. This is particularly important for field service apps or applications in areas with poor network coverage.

Frequently Asked Questions

FAQ about Web & Mobile Development

Technology & Platforms

Native or cross-platform – what do you recommend?

Native (Swift/Kotlin) for maximum performance and platform features. Cross-platform (Flutter/React Native) saves development time with one codebase. We advise based on your requirements and budget.

Which web frameworks do you use?

React and Next.js for most projects – stable, performant, well maintainable. Angular for complex enterprise applications. Vue.js when a lighter framework is preferable. Backend: Node.js, .NET, or Python.

Development Process

How does a typical project work?

Conception → UX/UI Design → Development in sprints → Testing → Launch → Support. You receive regular updates and can give feedback continuously.

Can we see the progress during development?

Yes, we work in sprints and provide access to a test environment. You see the app grow and can give feedback early – no surprises at the end.
