What we do01
Mobile app development for Berlin companies
Berlin is one of Europe's most dynamic tech cities. As an app agency based right here, we build fast, clearly and without unnecessary complexity – with our finger on the pulse of the Berlin scene.
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 app development for early-stage startups to complex platforms: every project starts with a business analyst, and we deliver a clear product structure. For iOS and Android, we rely on Flutter – one codebase, both platforms. We also routinely handle mobile app development in Berlin for more complex requirements.
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 keep improving the product.
Location02
App development in Berlin: startups, scale-ups and the public sector
01
What shapes the location
Berlin is Germany's largest start-up hub. Products in e-commerce, fintech, health, mobility and business software are built here — often with an international team and English as the working language. Add federal authorities, associations and cultural institutions with their own demands on accessibility and procurement.
02
Typical projects
Founders need an MVP that reaches users in two to three months and carries a funding round. Growing companies need reinforcement for an existing product or the move from a builder to custom code. Berlin is our base: workshops, acceptance and quick alignment are possible in person here too. More on the solutions for startups page.
Our process03
How we work with our Berlin clients
This is how your app comes to life – step by step, transparent and easy to follow.
Free initial consultation
We dive into your idea together, 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 process 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 day one.
Design
From wireframes to a complete design concept and interactive prototype – clean visuals, a smooth flow and a consistent UI kit.
Development
We use FlutterFlow for fast core features and extend it 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.
Collaboration04
Working with companies in Berlin
Our team is based in Berlin. We coordinate requirements, decisions, and progress with your team through a clear shared delivery process.
A Berlin-based development team
Xmethod is based in Berlin. Project discussions, workshops, and reviews can take place online; we agree on the most useful format at the start.
Your first consultation
We start with your business goals, users, existing systems, and main requirements. Together, we determine the right next step for the project.
In-person meetings
If an in-person workshop would benefit the project, we discuss availability, location, and arrangements in advance.
Discovery and sprint reviews
Discovery helps us map user journeys, integrations, and release priorities. Sprint reviews let your team see completed work and give feedback on what comes next.
Your project contact
A designated project lead coordinates communication, tracks open questions, and keeps you informed about progress and decisions that need your input.
Testing during development
Your team receives test builds, records feedback, and agrees necessary changes with us before the app is released.
Support after launch
Before launch, we agree on the support your application needs. Depending on scope, this can include bug fixes, compatibility updates, monitoring, and further development.
