The Flutter app: one codebase that runs everywhere.
A Flutter app is an application built with Google's open-source framework Flutter – from a single codebase for iOS, Android, Windows and macOS. It combines native performance with half the development and maintenance effort. Here you'll learn what sets Flutter apps apart, what they cost and when they are the right choice.
Natively compiled
Flutter apps are compiled to machine code – as smooth as a native app, because technically they are one.
Proven in production
Google Pay, the My BMW App, eBay Motors and Nubank are Flutter apps with millions of users.
Ours too
Pauly, our own shopping list app, is a Flutter app – live in both stores.
What sets a Flutter app apart.
- One codebase for everything – iPhone, Android, Windows, Mac – the same app, the same code. Every feature and every fix is built once instead of four times.
- Identical look everywhere – Flutter renders the interface with its own engine – your design looks exactly the same on every device, regardless of manufacturer quirks.
- Native speed – Ahead-of-time compilation to machine code and 60+ fps rendering – no stutter, no web-view sluggishness.
- Faster development – Hot reload shows changes in seconds and the rich widget system speeds up UI work – your budget goes further.
- Future-proof – Open source, actively developed by Google, a huge ecosystem – one of the most widely used app frameworks worldwide for years.

Full explanation on our page “What is Flutter?”
What Flutter apps are especially good for.
Consumer apps (B2C)
Shops, booking, fitness, community: fast iteration, both stores at once, a consistent brand experience.
Business apps (B2B)
Field sales, data capture, approvals, dashboards – offline-capable and connected to your systems.
MVPs & startup products
Maximum learning speed per euro: one codebase, both platforms, hot-reload pace.
Apps that need desktop
When Windows/Mac is needed alongside mobile, Flutter's architecture advantage really pays off.
Chat & real-time
Messaging, live updates, collaboration – see our dedicated page on the Flutter chat app.
Edge cases
Extremely hardware-heavy apps (specialist sensors, high-end 3D) get an honest assessment – sometimes native or a hybrid approach is better.
A Flutter app you can try: Pauly.
Instead of theory: install our own Flutter app and judge the speed and feel for yourself.
Pauly – dictate your shopping list
Pauly is our voice-controlled shopping list app – a Flutter app with on-device speech recognition, automatic categorization, store walking-order sorting and real-time sharing. Works offline, no account needed, from one codebase for iOS and Android.
Frequently asked questions about Flutter apps.
What exactly is a Flutter app?
An app built with Google's open-source framework Flutter. The code is written in the Dart language and, for release builds, compiled directly to native machine code – so the app runs natively even though it was written only once.
Can you tell the difference from a “real” native app?
Not in everyday use: Flutter compiles to machine code and renders at 60+ fps. Apps like Google Pay and the My BMW App prove it at scale. You can test it yourself with our own app Pauly.
How much does a Flutter app cost?
It depends on scope – from a focused MVP to an app with a backend and integrations. Compared to separate iOS and Android builds you typically save 30–50% in development and even more in maintenance. Concrete numbers after the free initial call.
Does a Flutter app also run on the web or desktop?
Yes. Beyond iOS and Android, Flutter supports Windows, macOS, Linux and the web from the same codebase. Desktop details on our Flutter desktop app page.
How do I find the right partner for my Flutter app?
Ask for their own apps in the store, for honest statements about Flutter's limits, and for testable interim builds during the project. You get all three answers from us in the first conversation.
