Professional App Development
From idea to finished app: We develop native iOS and Android apps, cross-platform solutions with React Native and Flutter, and Progressive Web Apps – performant, secure and user-friendly.
What is App Development?
The different paths to mobile applications – and when which approach is the right one
Native vs. Cross-Platform vs. PWA
App development encompasses the conception, design and programming of applications for mobile devices and the web. There are three fundamental approaches:
Native apps are developed specifically for one platform (Swift/Kotlin) and offer maximum performance and full access to all device features. Cross-platform apps use frameworks like React Native or Flutter to cover both platforms with a single codebase. Progressive Web Apps run directly in the browser and can be installed like native apps.
The Right Approach for Your Project
The choice of development approach depends on several factors: budget, timeline, required device features and target audience. A native app is ideal for performance-critical applications or when deep hardware integration is needed.
Cross-platform is excellent for business apps and MVPs where fast time-to-market and consistent experience on iOS and Android are the priority. PWAs are ideal for content-driven applications and as a cost-effective alternative to the app store.
What Your App Could Look Like

Cross-Platform Apps
With React Native and Flutter, we develop apps that excel on both iOS and Android – with a single codebase for faster development and lower costs.
- React Native
- Flutter / Dart
- Shared Codebase
- Faster Time-to-Market
Progressive Web Apps
Web apps that feel like native apps: offline functionality, push notifications and home screen installation – no app store needed, for all devices.
- Offline Functionality
- Push Notifications
- No App Store Required

Backend & API Development
Performant backends and RESTful APIs form the foundation of every app. We develop scalable server architectures with Node.js, Laravel or Firebase.
- Node.js / Express
- Laravel / PHP
- Firebase / Supabase
- RESTful & GraphQL APIs
UI/UX Design
Thoughtful design determines the success of your app. We create intuitive user interfaces that delight – from wireframes through prototypes to the final design.
- Wireframing & Prototyping
- Material Design / iOS HIG
- Usability Testing
- Design System
App Maintenance & Support
After launch, the journey continues: regular updates, OS compatibility, performance monitoring and feature extensions keep your app up to date.

Frequently Asked Questions About App Development
Costs depend heavily on the scope of features, platform and design. Simple apps start in the low five-figure range, while complex applications with backend integration and multiple platforms can be significantly higher. We provide an individual quote after a requirements analysis.
Native apps offer the best performance and full access to device features. Cross-platform frameworks like React Native or Flutter enable faster development for iOS and Android simultaneously with slightly reduced native depth. The choice depends on your requirements, budget and target audience.
An MVP (Minimum Viable Product) can be developed in 8-12 weeks. Full apps with complex backends, authentication and multiple platforms typically require 4-6 months. After the concept phase, we create a realistic timeline.
Yes, we accompany the entire process from development through store optimization (ASO) to publication in the Apple App Store and Google Play Store. We handle guidelines compliance, screenshots, descriptions and the review process.
Yes, we offer long-term maintenance contracts with regular updates, bug fixes, OS compatibility updates and feature extensions. This ensures your app stays current and functional.
A PWA is a web application that behaves like a native app – with offline functionality, push notifications and home screen installation. PWAs don't require an app store and work on all devices with a modern browser.
