What we do01
App and web app development in Düsseldorf
Düsseldorf is a hub for demanding B2B solutions. As an app agency in Düsseldorf – from app design to the technical backend – we understand the high quality standards expected here: stable systems, clear documentation and traceable processes from day one.
UX/UI Design
Once the foundation is in place, we turn structure into experience. From wireframes to polished mobile screens with UI kits and a consistent design language.
Low-code development
From mobile apps for mid-sized companies to web apps for international clients: we build well-engineered solutions that integrate seamlessly into existing system landscapes. App development in Düsseldorf for complex requirements is routine for us.
Launch & Growth
We take your product all the way to the Apple App Store and Google Play. After go-live, we keep an eye on performance and continuously improve the product.
Location02
App development in Düsseldorf: retail, fashion and international corporations
01
What shapes the location
Düsseldorf is a location for retail, fashion, telecommunications and consulting, and home to many German subsidiaries of international companies, particularly from Japan. Decisions here are often made in alignment with headquarters abroad — in English and under corporate rules for security and brand.
02
Typical projects
In demand are customer apps with loyalty programmes, portals for dealers and partners, event apps for trade fairs and tools for sales. We deliver documents and alignment in German and English and follow headquarters' brand guidelines and approval processes. Development happens in Berlin, alignment by video. A good match: solutions for sales teams.
Our process03
Our process for Düsseldorf projects
How your app comes to life – step by step, transparent and easy to follow.
Free initial consultation
Together we dive into your idea, sketch the first user flows and show you how your product takes shape. You get structured insights and a clear plan.
Product Discovery
We define the business logic, design the database architecture and write detailed user stories. Your idea becomes a solid technical foundation.
Project estimate
The team breaks the project down into tasks. Priorities, costs and a realistic timeline – transparent and traceable from the start.
Design
From wireframes to a complete design concept and interactive prototype – clean visuals, smooth flow and a consistent UI kit.
Development
We use FlutterFlow for fast core features and extend with Flutter and Python for complex logic. You also get an admin dashboard to manage everything yourself.
App launch
Your product goes live on the Apple App Store and Google Play. We prepare the listings, set up integrations and monitor early performance.
Ongoing support
After launch, your product keeps evolving. Our team handles updates, performance checks and QA audits – so the product stays stable.

FAQ07
Questions about our App Agency Düsseldorf
Trusted by 50+ founders
The cost of mobile app development depends on the platform, feature set and integrations. On average, projects range between €15,000 and €60,000. After a free initial consultation, we give you a transparent estimate.
Yes. Alongside mobile apps, we also develop web app solutions. Many of our Düsseldorf clients need both a mobile app and a web-based admin panel – we build both as one connected system.
A typical project takes 4–12 weeks depending on scope. We work in 2-week sprints – you see progress early, test real builds and move confidently towards launch.
We develop for iOS, Android and the web using cross-platform development in FlutterFlow. One codebase, all platforms – faster launch, lower maintenance costs.
We start with people, not pixels: user stories, early wireframes, user behavior analysis. Then comes the complete design concept with a UI kit and an interactive prototype.
Yes, absolutely. Here's how it works with Xmethod in Düsseldorf: we handle the entire technical implementation – from system architecture to the store launch. You describe your goal, we deliver the product. No technical knowledge required.
We can sign an NDA on request. After that, everything you share with us stays private and protected – whether you work from Düsseldorf or anywhere else.
