In plain words: what is this page about?

This page is about apps for phones and the web. We can build an app for one type of phone. We can also build one app that runs on many phones. A web app that works like a phone app is a third way. The page shows how we plan, design and test your app. Tell us your app idea and we will talk it through.

Definition

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 high 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.

Our App Development Services

From native development to long-term maintenance – everything from a single source.

iOS & Android

Native App Development

High performance and full access to all device features. We develop native apps with Swift for iOS and Kotlin for Android – optimized for each platform.

  • Swift / SwiftUI (iOS)
  • Kotlin / Jetpack Compose (Android)
  • Full Hardware Access
  • Optimal Store Performance
One Codebase

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
  • SEO-Friendly

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
Long-term

App Maintenance & Support

After launch, the journey continues: regular updates, OS compatibility, performance monitoring and feature extensions keep your app up to date.

  • OS Compatibility
  • Performance Monitoring
  • Feature Extensions
Use Cases

Which Projects Benefit from an App?

Typical scenarios for mobile applications across different industries.

B2B Apps

Field service tools, ordering systems and customer portals for business clients – with ERP integration and offline functionality.

E-Commerce Apps

Mobile shopping experiences with push notifications, wishlists and seamless payment integration for higher conversion rates.

Internal Company Apps

Digital workflows, time tracking, inventory management and communication tools – custom-built for your internal processes.

IoT & Connected Apps

Apps for controlling and monitoring connected devices – from smart home to industrial control with Bluetooth, MQTT and REST APIs.

Customer Loyalty Apps

Loyalty programs, stamp cards and personalized offers that reach your customers directly on their smartphones.

Dashboard Apps

Real-time data, KPIs and reports available on mobile – for management decisions on the go with interactive charts and filters.

FAQ

Frequently Asked Questions About App Development

Costs depend heavily on the scope of features, platform and design. A simple app is considerably smaller in scope than a complex application with backend integration for multiple platforms. We provide an individual quote after a requirements analysis.

Native apps typically 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) is usually developed after a few weeks. Full apps with complex backends, authentication and multiple platforms typically require several 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 keeps your app 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.
