Flutter app development

Google's toolkit for apps that look identical on every platform, compiled to native code. A strong choice when a custom, highly animated interface is the point of the product.

What we deliver

Custom app interfaces, backend and release

Example budget

From £6,000

Up to 8 screens. One mobile platform. Add more screens and features later.

Typical MVP timeline

6–12 weeks

Scope and launch date agreed in week one.

The starting build assumes supplied designs and a standard schedule. Design, login, integrations and additional platforms are priced as additions. Hosting, subscriptions and support are scoped separately. Adjust this example to fit your product.

What Flutter is

Flutter is Google's open-source toolkit for building natively compiled apps for mobile, web and desktop from one codebase. Alibaba, BMW, Google Pay, eBay and Nubank ship products on it.

Instead of wrapping each platform's native components, Flutter draws every pixel itself. That gives complete control over the interface and the same rendering on every device, with smooth animation out of the box.

Why founders choose it

Interfaces that are exactly what was designed

Because Flutter renders its own widgets, custom designs, branded components and complex animation come out the same on iOS and Android, with no per-platform compromises.

One codebase, many targets

iOS and Android first, with web, macOS, Windows and Linux available from the same code when a product needs them. One team, one set of features, one release process.

Native speed

Flutter compiles to native machine code and skips the bridge between JavaScript and native that other cross-platform tools rely on, so startup is quick and animation stays smooth.

Fast iteration

Hot reload shows a change in under a second without losing app state, which is why you get a new build to try every Friday from the second week.

How the work runs

Week one is two scoping sessions that end with a screen list, a fixed price and a launch date in writing. From week two we build in short sprints with a weekly installable build. We handle store review and release on every platform you ship to, and the repository is yours from day one.

The stack we use

Dart and the current stable Flutter release, Riverpod or Provider for state, REST or GraphQL APIs, local databases where the app needs to work offline, Firebase or Supabase backends, and CI that runs tests and produces signed builds on every merge.

Questions founders ask about Flutter

Is Flutter suitable for a serious product?

Yes. Alibaba, BMW and Google use Flutter for apps serving millions of people. It scales from a focused MVP to a large, long-lived product.

How does Flutter compare to React Native?

Flutter gives you pixel-identical interfaces and a custom rendering engine; React Native gives you real native components and the largest hiring pool. Neither is wrong for an MVP. We recommend one on the discovery call based on your design ambitions and the team that will own the code later.

What does a Flutter app cost and how long does it take?

Start from £6,000 for up to eight screens on one platform, then add screens and features as the product grows. Design, login, integrations and additional platforms are priced separately. The calculator gives you a live estimate in about two minutes, and the price is fixed in writing after the two week-one scoping sessions. Most MVPs ship in 6 to 12 weeks. Launches with complex integrations or several platforms typically take 12 to 20 weeks. You get an installable build every Friday from the second week.
