An app is not an accessory – it is your product

The App Store decides in seconds whether users remain. A slow, loveless app costs reviews, conversions and trust. We develop apps that run fast, feel familiar and fit your business processes – instead of off the shelf.

iOS, Android – or both from a codebase

Choose your platform and see what we work with. We find the right way together – depending on users, budget and functionality.

Native iOS apps

For iPhone and iPad, we develop natively in Swift & SwiftUI – with full hardware performance and consistently according to Apple’s Human Interface Guidelines.

  • Liquid 120 Hz animations & native gestures
  • Face ID, Apple Pay, Push, Widgets & App Clips
  • Conform to the Human Interface Guidelines
  • Smooth App Store Review & Release

Native Android apps

For the huge variety of Android devices, we develop natively in Kotlin & Jetpack Compose – modern material design, clean on every form factor.

  • Material Design 3 & Dynamic Themes
  • Biometrics, Google Pay, Push & Widgets
  • Stable over many devices & resolutions
  • Clean Play Store Release & Staged Rollout

Cross-platform

One codebase, both stores: With Flutter or React Native, we deliver iOS and Android in parallel – ideal if budget and time-to-market count.

  • A code base for iOS & Android
  • Faster delivery, lower costs
  • Nearly native performance & look
  • Native modules where necessary

What we develop for you

From the native single app to the complete product with backend – everything from a single source, with a fixed contact.

Native iOS and Android apps

Full performance, hardware access and a look & feel that feels right on any platform.

Cross-platform apps

Flutter or React Native, if both stores from a codebase should be served faster and cheaper.

UI/UX design

From the user journey to wireframes to the clickable prototype – design that increases conversion and retention.

Backend and APIs

Secure interfaces, Auth, Realtime & Cloud backend – so your app can also handle load and data.

Modernisation and maintenance

Adopt, stabilize, deliver new features and continuously adapt to store specifications.

App Store Launch

Store setup, assets, ASO basics and a smooth review at Apple & Google – including staged rollout.

Technologies with which we build

We rely on proven, future-proof stacks – both native and cross-platform – and choose the right tool for each project.

UI/UX decides on success

For mobile apps, design is not a paint, but a function. We create experiences that feel fast, clear and valuable – and thus increase ratings, usage and conversion.

Intuitive

Operation you don’t have to explain – clear paths, familiar patterns, fewer breaks.

Barrier free

Contrast, Dynamic Type, VoiceOver/TalkBack – apps that everyone can use.

Performant

60–120 fps, fast loading times and smooth transitions – Speed is part of the design.

Brand loyalty

Your brand in every pixel – a consistent design system instead of a modular look.

This is how your app is created

Structured from the first idea to the stores – with transparent steps and a fixed contact.

1

Idea and strategy

Goals, users and platform choice – we sharpen the concept before code emerges.

2

UX and Prototype

Wireframes and clickable prototype – test early before it gets expensive.

3

UI design

Visual design system in your brand – pixel-accurate for iOS & Android.

4

Development

Native or cross-platform, in visible sprints – AI-supported, technically tested.

5

Test & QA

Device testing, TestFlight/Play beta and pre-launch quality assurance.

6

Launch and operation

Store release, monitoring, updates and further development at your side.

Frequent questions about app development

It depends on your goals. Native apps (Swift or Kotlin) offer maximum performance and full access to platform features. Cross-Platform (Flutter, React Native) delivers iOS and Android from one codebase – faster and cheaper. We recommend the path that suits users, budget and functionality.
Yes. We implement both platforms – either natively per platform or cross-platform from a common codebase. So your apps appear coordinated in the App Store and Google Play.
Yes. We adopt existing iOS and Android apps, stabilize them, develop new features and keep them compliant with current store requirements.
Yes. We set up App Store Connect and Google Play Console, prepare assets and metadata, accompany the review and ensure a smooth, if necessary staggered release.
Very important – for mobile apps, the operation decides on success. We design UI/UX from the user journey to wireframes to the clickable prototype and a brand-faithful design system.
