Mobile apps

Mobile app development for iOS and Android.

We develop mobile apps that users enjoy using and that are reliably connected to your data, back-end systems, portals and processes. Whether it’s a customer app, an internal application, a field service tool or a digital platform: a good app must work quickly, intuitively and reliably whilst on the move.

What is it for?

An app has to be more than just an extra screen.

Many apps start out as good ideas, but quickly lose their appeal in everyday use. They look modern, but are fiddly to use, too slow, not properly integrated, or simply not relevant enough for users.

A successful app is created when real-life usage scenarios are understood: Which task should be made easier whilst on the move? What data needs to be available? When is offline capability required? Which functions need to be particularly quick to access? And how can the app be maintained in the long term?

  • Mobile apps for iOS and Android
  • Cross-platform development with an efficient codebase
  • User-friendly UX and UI design
  • Secure connection to back-ends, APIs and data sources
  • Offline capability and synchronisation
  • Push notifications and real-time updates
  • Suitable for long-term maintenance and expansion

Services From the initial idea to the app in the app store.

We support app projects from the initial design stage right through to launch and further development. 

User guidance & app structure

We develop clear app workflows, intuitive functional logic and easy-to-understand interface structures to ensure the app remains easy to use in everyday life.

Cross-platform development

An efficient technical foundation for iOS and Android, ensuring your app works reliably on both platforms.

Back-end and API integration

A secure connection to your data, systems, portals, databases or external services.

Offline capability and synchronisation

Functions and data remain available even if the internet connection is temporarily poor or unavailable.

Push and real-time features

Notifications, status updates and the latest information reach users exactly when they are relevant.

Store launch and maintenance

We support the launch on the Apple App Store and Google Play Store, as well as ongoing maintenance, updates and further development.

Key factors for apps

Mobile apps must be easy to understand, reliable and useful.

An app is used differently from a website or a portal. Users expect short navigation paths, clear functions and an interface that works intuitively even on small screens. At the same time, the app must be technically well integrated to ensure that data remains up to date and processes run reliably.

Mobile usability for real-world scenarios

We design apps so that users can quickly find what they’re looking for, even when on the move. Our focus is on clear navigation, uncluttered interfaces, intuitive interactions and sensible prioritisation of functions.

Data where it’s needed

An app realises its full potential when it is connected to the right systems. We integrate back-ends, APIs, databases, portals and external services so that users can access relevant information and functions on the go.

Stability even with a poor connection

Mobile applications, in particular, must be able to cope with changing network conditions. Where appropriate, we develop offline functions, local caching and synchronisation to ensure the app remains reliable even when on the move.

How we work

From an app idea to a robust mobile application.

We develop apps based on specific use cases and technical requirements. What matters most to us is the task the app is designed to perform, the data it requires, and how reliably it integrates with existing systems.

1

Concept & Requirements

We identify target audiences, use cases, core functions, data sources and technical requirements. In doing so, we also assess which functions are truly essential and where the app should deliberately remain streamlined.

2

Structure & Functional Logic

We translate the requirements into a clear app structure: What sections does the application need? Which processes need to work seamlessly? What data is displayed or synchronised, and when?

3

Development & Integration

We develop the app across multiple platforms and integrate it with the necessary back-end systems, APIs, databases and portals. In doing so, we ensure stable data flows, clean interfaces and a technical foundation that is easy to maintain.

4

Testing, Launch & Further Development

We test usability, performance, synchronisation and typical usage scenarios across various devices. We then support the app’s launch, updates and long-term development.

Frequently asked questions about app development.

Good to know.

In many projects, we opt for cross-platform development because it allows us to efficiently develop for iOS and Android using a shared technical foundation. Native development is the best approach when there are specific requirements regarding performance, device functionality or platform behaviour.

Yes. Integrating with back-end systems, APIs, databases, portals or external services is a key part of our work. This enables the app to access relevant data and make processes accessible on mobile devices.

Where appropriate for the use case, we develop offline functions with local storage and subsequent synchronisation. This is particularly important for field staff, service teams, events, travel or when internet connectivity is unreliable.

Yes. We oversee the release on the Apple App Store and Google Play Store and provide support with the necessary technical and organisational steps.

Yes. An app should be regularly maintained, updated and improved after its launch. We provide support for updates, technical adjustments, new features and long-term maintenance.
