App solutions that can do more.
A world without apps? Hardly imaginable anymore. They organize everyday life, simplify processes, and bring brands closer to their target audiences. At the same time, the demand is growing: To be successful in the app market today, you need more than just a good idea. As an app agency with strategic foresight and technical excellence, we turn app concepts into digital products that work - and have an impact. Whether it's conception, UI and UX design, programming, or marketing: We accompany companies throughout the entire journey from vision to a market-ready app.
Apps need more than just code.
If you want a strong app, you need a partner who thinks of all disciplines - from the idea to the marketing. As an app agency with a digital focus, we combine strategy, design, development, and marketing under one roof. We do not deliver individual parts, but holistic solutions. Our project teams work closely together - with fixed contact persons, short distances, and high impact. This saves time, reduces costs, and ensures results that really work.

Our services - from the app idea to the app development
1. Strategy consulting & app conception
Together, we analyze company goals, target groups, and the market environment - and develop a sustainable concept for the app vision. We provide advice on the appropriate technology (native app, hybrid app, or PWA) and help to plan the project optimally.
2. UX Design & UI Development
We design intuitive interfaces with a clear focus on user experience. From information architecture to visual implementation, a design is created that not only inspires but convinces - on all devices.
3. App development for iOS, Android & PWA
Our developers program high-performing, secure, and scalable apps using modern tech stacks. Whether it's native app or cross-platform development, we find the right solution.
4. Backend Development & Interfaces
We develop custom backends, APIs, and databases that connect the app with the existing infrastructure. This creates a seamless digital ecosystem with efficient data exchange.
5. App Testing & Go-Live
Through systematic testing, we ensure quality and functionality - for a smooth user experience. We support the launch in app stores and also take over app store management upon request.
6. Support & Further Development
Even after the release, your app remains in motion. We take care of support, monitoring, updates, and continuous development - agile, reliable, scalable.
What makes an app successful
Behind every successful app is more than just good technology. It requires strategic clarity, an excellent user experience - and the right agency by your side. We accompany app projects holistically - with expertise, foresight, and a clear focus on impact.
What really matters:
Clarity of purpose instead of feature overload
Every app needs a razor-sharp goal - for users and for the business. Only those who know what the app should achieve can make the right decisions.
Market Understanding & Target Audience Knowledge
Good ideas are just the beginning. What is crucial is what the market needs. We analyze trends, competitors, and user behavior - data-driven and targeted.
UX & UI Design that inspires
Whether it's design or flow: Those who should stay must not get lost. We develop interfaces that work intuitively and bring joy.
Strong architecture & stable performance
Apps must run fast, securely, and reliably - on all devices. We rely on scalable architectures and performant code.
Agile development with a forward-looking perspective
Our developers think ahead - so that the app not only works today, but will be even better tomorrow.
Marketing with a plan
We develop the appropriate launch and marketing strategy - from app store optimization to social media.
Scalability & Further Development
What is an MVP today, can be an ecosystem tomorrow. We think modular - and develop apps that can grow with you.
Community & User Engagement
Returning users are worth their weight in gold. We help to build relationships - with clever features, push strategies, and content.
Foresight instead of flash in the pan
Success requires perseverance. That's why we don't think of apps as individual projects, but as digital building blocks of a strong brand.
Native app or PWA? The right solution for the right purpose.
Mobile apps and Progressive Web Apps (PWA) follow different approaches - and each has its strengths. Native apps are specifically developed for iOS or Android and offer maximum performance, full device access (e.g. camera, GPS), and a particularly smooth user experience. On the other hand, PWAs are web-based applications that feel like an app - without the need to download from the store. They run directly in the browser, are platform-independent, capable of working offline, and quicker to implement. The choice of which solution is suitable depends on the use case, budget, and user requirements. We provide transparent advice and develop the app that truly fits.
Digital solutions with depth
As a digital agency, the development of high-quality websites is our core business - from the initial idea to the final bit. But we think further for our clients: As an interdisciplinary team of strategists, UX designers, developers, and online marketing specialists, we bring together all digital disciplines under one roof. We not only develop software projects, we solve digital crises for brands. Preventive, acute, sustainable. Whether it's an app, platform, e-commerce, or content strategy: What we do follows a clear goal - creating digital impact that lasts.

FAQ - Frequently asked questions for an App Agency
How much does an app cost?
The costs for developing an app depend on many factors - for example, the desired functionality, the number of platforms (iOS, Android, Web), the design complexity, and whether a custom backend or interfaces to existing systems are needed. As an experienced app agency, we first analyze your requirements to create a tailored and transparent offer based on them. This way, you will receive a realistic assessment of budget, resources, and time required.
How long does an app project usually take?
The project duration depends on the scope and complexity of the app. A simple MVP (Minimum Viable Product) can often be implemented in 3-4 months. More extensive mobile applications with multiple features, complex logic, and backend integration require 6-12 months or more. Our agile working method ensures that you regularly see functioning interim results, can provide feedback, and that the project can be flexibly adapted to new requirements.
What advantages does a mobile app offer for companies?
A custom-made app strengthens the digital brand presence, optimizes internal processes, facilitates access to services, and creates new possibilities for customer interaction. Companies also benefit from direct user feedback, push communication, higher conversions, and a mobile experience that stands out significantly from the competition. As an app agency, we develop exactly these solutions - tailored to the market, target audience, and business model.
Is it worth having your own app for small and medium-sized enterprises (SMEs) as well?
In any case. Especially SMEs can accelerate digital processes, tap into sales potential, or strengthen customer loyalty with their own app - for example, through service portals, ordering solutions, or mobile product catalogs. Our team develops app projects that are both functional and economically viable - individually planned, efficiently implemented.
What happens after the app goes live?
The launch is not the endpoint - but the beginning of long-term support. As a full-service app agency, we offer hosting, maintenance, monitoring, regular updates, and targeted further developments. We also provide consulting and operational support on topics such as app store optimization, user feedback analysis, or new feature releases.
