App Agency

Cross-platform development makes it possible to create an app for both iOS and Android using a single codebase. Frameworks such as Flutter or React Native are used, which generate native code and therefore enable performance and user experience that are nearly identical to native apps. This approach shortens development time and reduces costs without making major compromises in performance.

Hybrid app development is based on web technologies such as HTML, CSS, and JavaScript and runs inside a native shell (WebView). This allows apps to be used across different platforms, but with certain limitations in performance and access to device-specific features. Hybrid apps are particularly suitable for software with low hardware requirements or for simple business and content apps that are intended to work both on mobile devices and on the web.

Whether cross-platform or hybrid – choosing the right solution depends on the requirements for performance, budget, and target audience.

The Internet of Things (IoT) connects physical devices with the digital world, enabling seamless control, monitoring, and automation. IoT apps serve as a central interface for managing device networks via smartphones, tablets, or web applications and for analyzing real-time data.

Whether in smart homes, Industry 4.0, healthcare, or logistics, IoT apps communicate with sensors, machines, and cloud infrastructures to streamline workflows. A secure agent ensures encrypted communication between IoT devices and backend systems. Through reliable connectivity, intelligent automation, and an intuitive user experience, innovative solutions are created that deliver real value for businesses and end users.

Augmented reality (AR) and virtual reality (VR) apps expand the possibilities of mobile software and create completely unique forms of interaction. AR apps overlay virtual content onto the real world, while VR apps create entirely virtual environments.

Whether interactive product visualisation, immersive training, AR-assisted navigation or virtual reality experiences in gaming and industry – modern AR and VR apps provide companies with innovative solutions for marketing, training, e-commerce and more. Thanks to powerful hardware and intelligent software integration, smartphones, tablets and wearables become gateways to augmented and virtual worlds.

Mobile software is created specifically for operating systems such as iOS and Android and must be installed on the device. Unlike web systems, many mobile applications also work offline because they are stored locally on the smartphone or tablet.

To ensure that the application is intuitive to use, it needs a touchscreen-optimised interface that adapts to different display sizes. Depending on the framework conditions, a native, cross-platform or hybrid variant may be suitable. While native systems offer maximum performance and device access, cross-platform and hybrid approaches enable faster implementation for multiple device environments simultaneously.

From business tools and e-commerce to IoT and AR, they are essential for modern technology-driven business models and successful user experiences.

A web application runs directly in the browser and does not need to be installed on the device. This enables cross-platform applications that work on desktops, tablets and smartphones. Modern web programming relies on technologies such as HTML, CSS and JavaScript to provide a responsive and touch-optimised user interface.

Unlike mobile apps, they are always online and access information from the cloud. Progressive web apps (PWAs) can even work offline and offer features such as push notifications. They are particularly suitable for business software, customer portals and SaaS solutions where easy maintenance and quick updates are crucial.

Wearable application development brings virtual worlds to smartwatches, fitness trackers, AR glasses and other wearable devices. Applications for Apple Watch (watchOS), Samsung Galaxy Watch (Tizen, Wear OS), Fitbit, Google Pixel Watch or AR headsets such as HoloLens and Meta Quest enable seamless interaction and open up innovative usage scenarios.

From health and fitness tracking to real-time alerts and control of IoT devices, wearables provide greater convenience, efficiency and personalised experiences. Optimised user interfaces and power-saving development make them perfectly suited to the requirements of small displays and mobile use.

Modern TV apps bring content, streaming services and interactive applications directly into the living room. Whether for Apple TV (tvOS), Android TV, Fire TV, Tizen (Samsung) or LG webOS, platform-optimised applications offer users an intuitive, high-quality experience on the big screen.

From video streaming and gaming to smart home control, TV services open up new possibilities for entertainment and interactive services. Optimised user interfaces, voice control and seamless integration into the TV ecosystem ensure maximum user-friendliness.

POS and kiosk apps optimise self-service processes, automate transactions and improve the customer experience. Whether order and payment stations in restaurants, check-in terminals in hotels or ticket machines in public transport, interactive applications enable intuitive and fast use.

Modern POS cash register systems offer comprehensive options for retail and catering, including cash and card payments, receipt printing, inventory management and the export of cash register reports. Interactive touchscreens are used in service and information terminals, for example for queue management systems, customer information or product configurators.

Thanks to seamless integration with hardware and backend systems, scanners, printers, NFC/chip readers, RFID technology, and ERP, CRM, and payment services can be flexibly connected – for a smooth, networked, and future-proof solution.

Modern in-flight entertainment (IFE) systems transform long flights into a personalised entertainment experience. Whether on integrated seatback displays or personal devices, passengers have access to films, series, music, games and live map views.

In addition to traditional entertainment, IFE services also provide Wi-Fi access, duty-free orders, meal reservations and travel information – all conveniently via passengers' own phones or tablets. Airlines are increasingly relying on bring-your-own-device (BYOD) solutions, which allow passengers to access the onboard network directly via a special interface.

With offline functionality, personalised content and seamless integration into aviation IT, modern in-flight applications ensure a comfortable, digital travel experience. 

Modern car displays offer much more than navigation and media control. They are the virtual cockpit for connected vehicles. Special automotive systems enable infotainment, voice control, vehicle diagnostics and intelligent assistants directly in the on-board computer.

Thanks to Android Automotive OS (AAOS), Apple CarPlay, Android Auto and manufacturer-specific software such as MBUX (Mercedes), VW MIB or Tesla UI, we can seamlessly integrate digital functions into the vehicle. Whether music streaming, real-time navigation, smart home control or personalised driving experiences – modern software combines mobility with digital convenience.

By connecting to cloud services, sensors and IoT infrastructures, modern in-vehicle apps offer a secure, personalised and interactive driving experience – tailored to the future of connected mobility.

In principle, development can be carried out independently, with freelancers or in collaboration with a professional app agency. Independent implementation makes sense if you have sufficient technical expertise but only a limited budget. If you don't have the time, a freelancer may be a good option, as you can outsource your project to them. However, keep in mind that with a freelancer, you are usually dependent on a single person, which entails certain limitations and risks. 

Especially for larger software projects, you have a clear advantage with an app agency. Development requires expertise in project management, UX/UI design, backend architecture, and quality assurance. With an agency, companies benefit from an interdisciplinary team with experience in app internationalisation, accessibility and modern methods such as artificial intelligence (AI) and machine learning. We also take a holistic approach – from strategy to design and from development to hosting. But we are also happy to step in wherever you need us.

The costs depend on several factors, such as the range of functions, the complexity and the desired environment. In the free initial consultation, we will work with you to clarify which functions you need and put together a transparent offer that is tailored precisely to your requirements. This gives you a clear overview of the costs right from the start.

All in all, it makes sense to divide the implementation into individual project phases and thus also spread the costs. For many of our customers, we develop a basic version in Step#1, which we then expand step by step. With this so-called MVP, you not only reduce the costs of the first project phase, but also your time to market. A win-win situation. 

The duration of implementation depends on the scope and complexity of the project. A simple application with basic functions can be completed within 4 to 8 weeks. For larger and more complex projects, we usually plan 3 to 6 months for the first version. 

We work in an agile manner throughout the entire process, which means that you are always informed about the current status and can provide feedback, and we can respond flexibly to changes. Together, we ensure that your app is completed on time and to the highest quality standards.

Structured app project planning ensures that development, quality assurance and launch run smoothly. Using agile methods such as Scrum, we employ a flexible, multi-step process:

• Concept & strategy: Definition of target group, functions and business model. Decision on app development frameworks and interfaces.
• Technical planning: Selection of the app development environment and ensuring stable interface development for CRM, ERP or other systems.
• Design & prototyping: Creation of interactive wireframes to optimise the user experience (UX).
• Development & testing: Iterative programming with code reviews, quality assurance and continuous integration & deployment for error-free releases.
• Launch & optimisation: App Store submission, adaptation to App Store guidelines and use of App Store keywords to increase visibility.
• Operation & further development: app maintenance, troubleshooting and regular app updates to ensure long-term success.

Careful planning minimises risks and ensures that the application is developed efficiently and optimised sustainably.

Absolutely! Thanks to agile project management methods, we can work on designs and features flexibly. What's more, prototyping and MVP development allow you to see and test an interactive version of your software early on, before it is fully programmed. Just let us know if your requirements change. This gives you full control over progress and ensures that your app meets your exact specifications. Features such as geolocation services or AI-supported features can be integrated and optimised step by step. App localisation also allows it to be adapted to different markets. Regular updates and prototypes give you insight into the development process and allow you to initiate adjustments at an early stage, saving time and money.

Even after launch, we won't leave you on your own. Our goal is to support you in the long term and ensure that your software remains a success.

Before it goes live, it goes through an approval process in Google Play and the Apple Store. We take care of the submission, ensure that all guidelines are met, and optimise the listing for maximum visibility.

After release, we take care of app maintenance, bug fixing and further development. This includes regular app updates, performance optimisation, adaptation to further guidelines and markets through app internationalisation, and optimisation of app accessibility for better usability. With the help of app continuous integration & continuous deployment, we ensure stable, error-free updates without downtime. This ensures that it always remains stable, secure and state-of-the-art.

Yes, we can seamlessly connect your application to existing infrastructures, such as databases, ERP, CRM or other backend software.

Our developers are well-versed in API integrations and interfaces. This allows us to ensure that your app interacts optimally with your existing workflows and tools. This saves you time and makes your business even more efficient. If your existing solution does not have an API, we can also help you implement one.

A well-placed application in the App Store and Google Play Store requires App Store Optimisation (ASO). We analyse App Store keywords, categories, features and optimisation tools to increase visibility. To do this, we perform regular app updates, optimise performance and adapt to new guidelines. App Store submission and promotion help to improve App Store ratings and reviews and retain users in the long term. App store reviews are also a valuable source of user feedback. It is worth reading them regularly and incorporating them into further development.

Successful app user acquisition combines app store promotion, advertising integration and virality strategies. To increase app retention and reduce churn rate, we rely on push notifications, personalised content and continuous improvements through app feedback collection.

High app quality requires code reviews, quality assurance and version control. Through comprehensive testing, we identify potential weaknesses at an early stage and continuously optimise. With App Store Analytics, we monitor performance, identify potential for improvement and ensure smooth integration into existing systems. An AI agent automates workflows, analyses data and supports data-based decisions to make them even more efficient. And if an update is necessary – whether for new features, performance optimisation or placement adjustments – we accompany you through the further development process.
