Design survives both platforms
Flutter draws the interface itself, so the product ships as designed: no per-platform drift, no OEM widget surprises, one visual QA pass instead of two.

Flutter
Your design, rendered pixel for pixel on iOS and Android from one Dart codebase. Built for products where the interface is the product.
What it is
Flutter ships iOS and Android from a single Dart codebase, but its real difference is how it draws: the framework renders every pixel itself through the Impeller engine instead of mapping to platform widgets. Your interface looks and behaves identically on a three-year-old Android phone and the latest iPhone, and one team maintains one backlog for both stores.
It wins when the interface is the product: brand-heavy consumer apps, animation-rich experiences, custom design systems that would be expensive to build twice. Because Flutter compiles Dart to native machine code and controls the whole render pipeline, performance is predictable, and 60 or 120 frames per second is an engineering budget, not a hope. The same codebase reaches desktop and embedded targets when that matters.
The trade-offs are real and we name them. Dart is a separate skill, so an existing React web team carries over less than with React Native. Apps ship larger than native ones, platform-specific features go through platform channels into Swift and Kotlin, and a platform-conventional look takes deliberate work. We tell you before the project, not during it, whether those costs are worth what Flutter buys you.
Why it works
Performance as a budget, not a hope
Dart compiles ahead of time to machine code and Impeller renders without shader jank. We set frame-time and startup budgets in CI and hold them.
One team, one backlog
Typical products share well over 90 percent of code between platforms. Features land in both stores the same day, and a bug is fixed once.
Room to grow beyond phones
The same codebase targets desktop and embedded screens. If a kiosk, tablet or in-car surface is on your roadmap, Flutter reaches it without a rewrite.

How we build with it
01
Prove the hardest screen first
We build your riskiest interface, the signature animation or the dense dashboard, as a spike in the first days. The economics of the whole project rest on it, so it goes first.
02
Design system as code
Your brand tokens, typography and components become a Flutter package with a live gallery. Designers review real rendered widgets, not approximations.
03
Vertical slices to both stores
TestFlight and a Play internal track from the first sprints, a full slice of the product at a time. Progress is measured in installable builds.
04
Measure before optimizing
Frame times, startup and app size are tracked in CI from week one. When a number leaves its budget we fix it that sprint, not before launch.
What you get
Production iOS and Android apps from one Dart codebase
Your design system as a documented Flutter package
Platform channel integrations in Swift and Kotlin, documented
CI/CD pipeline with automated delivery to both stores
Test suite: unit, widget and integration tests
Performance report: startup time, frame budgets and app size
Common questions
Will a Flutter app feel native?
It feels like your product, which is exactly the point for design-led apps. Flutter ships faithful Material and Cupertino widget sets, and we adapt navigation gestures, scroll physics and haptics per platform. If your app should above all look like a stock Apple app, native or Kotlin Multiplatform is the honest recommendation.
Is Dart hard to hire for?
The pool is smaller than JavaScript's, but Dart is a small, typed language that an engineer coming from TypeScript, Kotlin or Swift picks up in days. Teams we hand over to routinely staff Flutter roles with strong mobile or backend engineers rather than searching for the keyword in a CV.
Flutter or React Native?
If your product is design-led, animation-heavy or needs identical rendering everywhere, Flutter. If you have a React web team whose code and people you want to leverage, React Native. We build both, and the recommendation you get is written down with reasons, not a preference.
How big and fast are the apps, really?
A minimal release build is around 10 MB per platform before assets: larger than native, but rarely decisive. At runtime it is compiled machine code with GPU rendering; on mid-range Android hardware, startup and scrolling are where Flutter routinely beats interpreted stacks. If every megabyte matters in your distribution, we will tell you what native would save.
