Digitalization has long been more than just a technical trend — it is an economic necessity. In Kiel, too, more and more companies recognize the potential of digital solutions to optimize processes, tap into new target groups and remain competitive in the long term. An individually developed app can be a central component of this. Whether as a digital customer portal, an internal tool or a mobile product — apps offer numerous opportunities to expand business models or make them more efficient. In a diverse business location such as Kiel — characterized by maritime industry, science, tourism and healthcare — this creates industry-specific opportunities that we use together with our customers.

Our team designs, designs and develops individual apps that are precisely tailored to the requirements of your target group and industry. We support you from the initial idea through technical implementation to long-term support for your application. Whether native app for iOS or Android, progressive web app or hybrid solution — we deliver tailor-made products that not only work, but also create real added value.

App development in Kiel:
‍Step by step to a successful app

Strategic planning and UX-oriented design

Each app starts with a thorough analysis: Who are the users? Which problems should the app solve? Which functions are essential? In workshops and requirement analyses, we jointly lay the basis for a successful project. Tools such as Figma are then used to create interactive prototypes that simulate the subsequent user experience. Our UX/UI designers pay attention to intuitive operation, clear structures and modern aesthetics. User feedback, usability tests and iterative optimization create an interface that is not only beautiful but also logical. Early visualization enables quick feedback and reduces subsequent adjustment costs — an advantage that our customers from Kiel particularly appreciate.

Development with a focus on scalability

For technical implementation, we rely on modern frameworks, clean code and agile methods such as Scrum. Depending on the project requirements, we develop natively (with Swift or Kotlin), hybrid (e.g. with Flutter or React Native) or as a progressive web app (PWA). Our dev teams work in short sprints, regularly coordinate with customers and continuously test new features. The result: a stable app that can be flexibly extended and maintained over the long term. Through automated tests and code reviews, we ensure that every version of your app is error-free, performant and secure — on all devices and operating systems.

Cloud-based backend architecture

The backend is the technical backbone of every app. We develop scalable and secure server structures with cloud services such as AWS, Firebase or Supabase. Our systems are based on frameworks such as Node.js, Django or Spring Boot — modular, efficient and low-maintenance. We value performance, data protection and expandability. Databases such as PostgreSQL, MongoDB or Firestore ensure stable and high-performance storage of your data. We develop interfaces based on REST or GraphQL to connect your app with internal tools or external systems. The use of serverless architecture enables flexible load distribution and reduces operating costs — ideal for companies in Kiel that want to grow quickly.

Visibility through strategic app marketing

An app can only be successful if it is also found. That is why we offer comprehensive support in digital marketing: from App Store Optimization (ASO) to SEO and social media campaigns. We analyse competition, identify relevant keywords and optimize titles, screenshots and descriptions of your app. This is complemented by targeted advertising measures — such as Google Ads, Instagram campaigns or influencer collaborations. We also use retargeting strategies to retain existing users in the long term. This makes your app a success not only technically but also commercially.

Digital app innovation in Kiel Progress through technology

PWAs

Progressive web apps — the universal solution in the browser

Progressive web apps (PWAs) offer companies in Kiel the opportunity to have a mobile presence — completely without a classic app installation. These browser-based applications combine the best of web and native app: They run offline, send push notifications, store data locally and offer high loading speeds. For companies with a limited budget or clearly defined use cases — such as booking systems, information portals or customer services — PWAs are ideal. They work across devices and platforms, are easy to update and do not require an app store. For many Kiel SMEs, this means: less effort, faster time-to-market and lower operating costs. Our PWAs are based on modern technologies such as React, Vue or Angular and are designed in such a way that they remain maintainable, scalable and secure over the long term. They're a particularly good fit for companies that want to deliver digital services quickly and efficiently — without sacrificing performance or user experience.

Hybrid apps

Multi-platform capable with one code base

Hybrid apps make it possible to operate Android and iOS at the same time — with just one set of codes. For companies in Kiel, this is a major advantage: shorter development time, simplified maintenance and reduced costs with a high reach. Frameworks such as Flutter or React Native enable high-performance apps that work natively on both operating systems. The user interface is consistent, functions can be controlled centrally, and updates are rolled out synchronously. The result: less effort for your team, faster iterations and a consistently positive user experience. For many Kiel companies that want to scale a digital product quickly or reach different target groups at the same time, this solution is the ideal compromise between flexibility, speed and quality.Our hybrid projects integrate modern interfaces, databases, animations and security logic — all developed on one platform but ready for use on many devices.

Tailored digital applications

Standard solutions often quickly reach their limits. Especially in a city like Kiel, where the maritime economy, energy, science and tourism come together, companies need digital products that are precisely tailored to their processes. We do not develop “off-the-shelf” software, but tailor-made applications that digitally map and optimize individual processes. We start with a thorough analysis of your existing infrastructure and business goals. Together, we identify bottlenecks, develop a clear range of functions and design a digital product that fits seamlessly into your daily processes. Our app solutions adapt flexibly, can be expanded modularly and grow with your company. Whether it's a customer portal, sales app or an internal tool — we bring your project into a scalable and powerful app architecture.

Long-term support and development

Publishing an app is not an end point, but the start of a digital life cycle. That is why we support Kiel companies even after the launch — with a holistic support model that ranges from continuous maintenance and updates to strategic development. Our aim is that your app not only works, but remains successful in the long term. We regularly carry out performance analyses, update security protocols and adapt functions to new technological standards or market requirements. Automated test systems, monitoring tools, and structured release plans keep your applications stable, secure and competitive. On request, we can train internal teams so that they can independently manage new content or make minor changes. This allows you to remain technically independent and yet well looked after.

Digital transformation as a strategic advantage

Digitalization is not a short-term project, but a profound change in corporate strategy. We help Kiel companies to use digital technologies in a targeted manner to automate internal processes, create new services or expand existing business models. Together with you, we develop a digital strategy that fits your industry, resources and corporate culture. In doing so, we analyse your existing data structures, workflows and customer interfaces and show where technology can create real added value — whether through real-time communication, networked data flows or AI-based decisions. This makes your app more than a digital product: it becomes an integral part of your entrepreneurial success.

Innovative technologies for modern App development in Kiel

Efficient prototypes with Figma

The success of an app starts in the design phase. With Figma, we create clickable prototypes that realistically represent design, user flow and functionality — long before actual programming. These prototypes enable stakeholders to provide early feedback and make adjustments before time and budget flow into code. We use iterative design processes where each new version is based on user feedback from the last. The result: a visual and functional framework that is convincing even before launch — and reduces subsequent changes to a minimum. Figma offers maximum transparency and efficiency in the development process, especially for complex projects in Kiel.

Optimized front-end technologies

The frontend is the face of your app — and decisively responsible for user satisfaction. We use modern frameworks such as Vue.js, Svelte or Astro to create visually appealing, high-performance and modular user interfaces. These technologies enable us to load interactive content at lightning speed, develop responsive designs and implement individual UX concepts with technical precision. Our front ends are not only visually convincing, but also future-proof: They can be easily extended, adapted and combined with new features. Through the targeted use of component-based code, your applications remain structured and maintainable even as complexity grows.

Secure and scalable backend systems

In the background, a strong backend ensures smooth processes. We develop backend structures based on Node.js, Django, Spring Boot or serverless architectures such as AWS Lambda. These systems are highly available, fail-safe and scalable — ideal for companies in Kiel with increasing numbers of users or data-intensive applications. Our databases — such as PostgreSQL, MongoDB or Firestore — are flexible and GDPR-compliant, while APIs (REST/GraphQL) ensure seamless connections with third-party services or existing internal systems. Security is always paramount: Encryption, access control and continuous monitoring processes are an integral part of our infrastructure.
