Flutter app development – one codebase for iOS, Android, Windows and Mac.
You need an app that works equally well on every device – without paying parallel teams for iOS and Android? With Flutter we build your application from a single codebase: that saves development time, keeps maintenance lean and delivers the same well-crafted interface on every platform. From first concept to store launch – or from whatever point you need us.
New apps
From MVP to finished product – including UI/UX design and store launch.
Existing apps
Feature development, modernization, bug fixing and ongoing support.
Individual workstreams
Project management, design, architecture consulting or code audits as standalone services.
What we develop for you.
Whether it's a brand-new app, further development of your existing app, or support in a single workstream – we join exactly where you need us.
New App Development
From idea to launch: concept & requirements analysis, UI/UX design, cleanly structured development, quality assurance on real devices and submission to the App Store and Google Play.
Request a new appMVP Development
The smallest meaningful version of your app: the core feature done really well, genuinely usable rather than a throwaway prototype, measurable from day one. Invest modestly, expand deliberately.
Discuss your MVP ideaFeature Development & Maintenance
New features, updates for new OS versions, bug fixing, technical modernization and ongoing support – including apps we didn't originally build.
Request maintenanceApp Design (UI/UX)
User flows, wireframes, visual design and a design system – tightly interlocked with development so your design lands in the finished product without friction.
Request designFlutter Migration
Two separate native apps or an outdated cross-platform solution? We move your app step by step onto a shared Flutter codebase – low-risk, while it keeps running.
Evaluate a migrationConsulting & Tech Audit
Technology choice, architecture, code audit or a second opinion – an honest, well-founded assessment without sales pressure.
Request consultingWhy Flutter is the foundation.
Flutter is an open-source framework by Google for building apps for multiple platforms from one codebase. For your project, that means:
- One codebase, multiple platforms – iOS, Android, Windows and macOS from the same project – instead of separate builds per system.
- Faster time to market – Code is written and maintained once – updates ship on all platforms at the same time.
- Consistent look – Flutter's own rendering engine draws your app on every device exactly as designed.
- Native performance – Release builds are compiled to native machine code – smooth, not a “website in a wrapper”.
- Established & future-proof – In production at Google Pay, BMW, Nubank, eBay and Alibaba – actively maintained by Google.

Is Flutter the right fit for your project?
That's exactly what the first call is for – free and straight to the point. Describe your app idea in a few sentences and we'll reply with an honest technology assessment.
Flutter app development, proven in the store.
We don't just build for clients – we run our own Flutter app and know the entire lifecycle.
Pauly – dictate your shopping list
Pauly, our voice-controlled shopping list app, was built with exactly the process we offer you: MVP first, then data-driven expansion with automatic categorization, store walking-order sorting and real-time sharing. One codebase, both stores, in ongoing operation.
How we work.
Intro call & goal setting
We understand your project, your target audience and your technical constraints.
Concept & proposal
You get a clear assessment of scope, approach and timeline.
Design & development
Your app takes shape in short, manageable steps – you see visible results early.
Launch
We publish to the app stores or deliver the desktop version.
Operations & evolution
On request, we support your app after launch with maintenance and new features.
The process is in place – all that's missing is your project.
The sooner we know what you're building, the sooner your app is in the stores. A short description is all it takes for an initial assessment within 24 hours.
Frequently asked questions about Flutter app development.
Can't I just build a Flutter app myself with AI?
For a prototype: yes. For a product that survives App Store review, scales and stays maintainable: rarely. AI generates Dart code, but not the architecture, state management, store compliance and the many details that decide success. We are AI-first ourselves and use AI in every Flutter app development project – faster, but with the experience of running our own app in the stores. That combination is what you get when you have your app built with us.
How much does Flutter app development cost?
The feature scope decides: a focused MVP costs far less than an app with a backend, accounts and integrations. The Flutter advantage: iOS and Android come from one codebase – you don't pay for double development. After the initial call you receive an itemized, traceable estimate.
How long does development take?
Depending on scope, an MVP is often testable within a few weeks; complete apps with a backend and store launch take correspondingly longer. Hot reload and the shared codebase make Flutter projects measurably faster than separate native builds.
Do you also take over existing Flutter apps?
Yes. We work our way into existing code methodically, run an audit to map its state and risks, and propose a realistic path – careful evolution or targeted refactoring.
When is Flutter not the right choice?
For very deep integration with platform-specific hardware or specialist frameworks, native code can be the better base – though a native module inside the Flutter app is often enough. We give you that assessment honestly before the project starts.
Which well-known apps are built with Flutter?
Among others: Google Pay, the My BMW App, eBay Motors, Nubank, Alibaba's Xianyu and apps from Toyota – plus our own app Pauly, which you can test yourself.
