The Flutter agency with its own app in the stores.
We are a Flutter agency in the truest sense – and with Pauly we run our own Flutter app on the App Store and Google Play. That hands-on experience goes into every project: new apps, MVPs, migrations, and taking over existing Flutter codebases. One codebase, every platform, honest advice.
Flutter focus
We don't spread ourselves across ten frameworks – Flutter and Dart are our daily tools of the trade.
Our own product
Pauly: a voice-controlled shopping list app, live in both stores – from a single codebase.
Full coverage
iOS, Android, Windows and macOS – plus backend, CI/CD and ongoing store operations.
Why we build on Flutter.
Flutter is Google's cross-platform framework: one codebase for every platform, compiled to native machine code. For you, that means:
- One budget instead of two – iOS and Android come out of the same project – development and every later change are paid for only once.
- Native performance – Flutter apps are AOT-compiled to machine code and render at 60+ fps – no web-view compromise.
- Pixel-perfect consistency – Flutter's own rendering engine draws your app identically on every device – your design stays your design.
- Desktop as a next step – Windows and macOS versions grow out of the same codebase – no separate project needed.
- Proven at scale – Google Pay, the My BMW App, eBay Motors, Nubank, Alibaba and Toyota all run Flutter in production.
Framework
Flutter – open source by Google, launched 2017, written in Dart, AOT-compiled.

Test our work – in the store.
The most important question to ask any Flutter agency: “Show me an app you run yourself.” Here is ours.
Pauly – dictate your shopping list
Pauly is our own Flutter app: dictate your shopping list by voice, automatic categorization of over 3,000 grocery items, sorting by store walking order, real-time sharing for families and flatmates. On-device speech recognition, works offline, ready to use without an account – one codebase for iOS and Android.
Why a Flutter agency when AI can code?
You can “build an app yourself with AI” today – and you almost always end up with a prototype that falls apart in real use. We are an AI-first agency: we build every Flutter app AI-assisted because it makes us faster. The difference between AI code and an app that survives in the store is experience.
- AI generates code – not a finished product – A prompt delivers widgets, but not the architecture, state management, store compliance and performance that shippable Flutter apps depend on. Getting from prototype to a real app is what we do every day.
- We run our own Flutter app in the stores – With Pauly we run our own Flutter app live on the App Store and Google Play. We know app review, performance tuning and real user feedback from operating a product, not from a tutorial.
- AI-first – and honest about it – Anyone claiming they build without AI today is probably not telling the truth. We use AI deliberately: it noticeably speeds up development and the timeline. The quality still comes from experience – not from the model.
- The tweaks that decide success – Offline behavior, battery usage, the platform quirks of iOS and Android, typical App Store rejection reasons, update and migration strategy: exactly the details where AI DIY apps fail are our craft.
- Maintainable instead of throwaway code – Unreviewed AI code quickly becomes unmaintainable. We build cleanly structured, documented Dart code – so your Flutter app can still be developed further in two years.
How we work.
Intro call & technology check
We honestly assess whether Flutter fits your project – and tell you if it doesn't.
Concept & proposal
A clear feature scope, a transparent effort estimate, defined milestones.
Design & development
Short cycles, testable builds on your devices, a direct line to the developers.
Launch
App Store and Google Play at the same time – review guidance included.
Operations & growth
Monitoring, maintenance and data-driven iteration after launch.
You've seen how we work – all that's missing is your project.
The first step takes five minutes: describe your project, get an initial assessment – no strings attached, usually within 24 hours.
Frequently asked questions about our Flutter agency.
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 build every Flutter app AI-assisted – faster, but with the experience of running our own app in the stores. That combination is what you get when you have your Flutter app built with us.
Why a specialized Flutter agency instead of a full-service agency?
Specialization means depth: we know Flutter's strengths, limits and ecosystem from daily work and from running our own product. That leads to better architecture decisions, more realistic estimates and faster development than teams that “also do Flutter”.
Do you have references?
You can install our most important reference yourself: Pauly, our voice-controlled shopping list app, live on the App Store and Google Play. It shows our quality standard more honestly than any glossy case study.
How much does a Flutter app cost?
The scope of features sets the range – from focused MVPs to apps with backends, accounts and integrations. The Flutter advantage: iOS and Android from one codebase means no double costs. After the initial call you get a concrete, itemized estimate.
Do you take over existing Flutter projects?
Yes. We start with a code audit, name the state and risks honestly, and then take on further development and maintenance – even if the app was built by another team.
When do you advise against Flutter?
For apps that go extremely deep into platform-specific hardware or specialist frameworks, native can be the better foundation – though often a native module inside the Flutter app is enough. You get that assessment from us before the project starts, not after.
