FLUTTER · DART · CROSS-PLATFORM

Flutter app development, one codebase for iOS and Android.

We build Flutter apps in Dart that ship to the App Store and Google Play from one codebase, with native code where a feature needs it. We will also tell you when native is the better choice, because we build both. You work directly with the engineers building your product. No account managers, no hand-offs.

Our clients

A few of the teams we have built for.

What we build

One codebase, two stores.

New cross-platform apps

One Flutter codebase for iOS and Android, with a design that respects each platform's conventions.

Native bridges

Platform channels into Swift and Kotlin for camera, sensors, payments or AR when a plugin is not enough.

MVPs on a budget

One team and one codebase to get a first release onto both stores and learn from real users.

Backends and integrations

Firebase or your own APIs, with offline storage and push notifications.

Both store launches

Store listings, review submissions and releases for the App Store and Google Play.

Flutter or native?

If the app leans on AR, heavy graphics or deep OS features, we will say native fits better before you commit.

Selected mobile work

Mobile apps we have shipped.

We choose the framework per project, so not every app here is Flutter. Each one is live and linked.

iOS · Android · Driver app

DeliverEnd

An on-demand delivery platform: the customer app, plus a driver app that pays out as soon as a delivery is done.

App Store

iOS · 3D capture

Plinth 3D Scanner for Art

Turns artworks, objects and spaces into 3D models on iPhone, using 48 MP photogrammetry or Gaussian splatting.

App Store

iOS · Performance training

Soma NPT

A neuro-performance training app that drills reaction speed and decision-making, for a Swiss client.

App Store

iOS · Personal safety

Crimesly

A personal safety app with real-time monitoring and dispatch support.

How we work

Four steps, and you own the result.

  1. 01

    Scope

    We agree what the first release does, how success is measured, and what it costs, before any code.

  2. 02

    Design and prototype

    Clickable screens in Figma, tested with real users where we can, so changes are cheap.

  3. 03

    Build and test

    Short sprints with a build you can install every week. Crash reporting and analytics go in from day one.

  4. 04

    Launch and hand over

    Store listing, review submission and release. The code, accounts and documentation are yours.

FAQ

What teams ask before choosing Flutter.

When is Flutter the right choice?

When you want iOS and Android from one codebase and the app is mostly interface and data. It is the wrong choice when you need deep platform features like ARKit, where native wins.

Does a Flutter app feel native?

Done properly, yes. We follow each platform's conventions rather than shipping one identical interface to both, which is what usually makes cross-platform apps feel wrong.

Can Flutter handle complex animation?

Yes. Flutter renders its own frames, which makes bespoke motion easier than on either native platform.

Can we add native code later?

Yes. Platform channels let native modules sit alongside the Flutter codebase, so a feature that needs Swift or Kotlin is not blocked.

How much does one codebase save?

Typically less than half. The interface is shared, but testing, store submission and platform-specific work still happen twice. We are straight with you about that in scoping.

Do you build the backend as well?

Yes. Laravel or Node APIs, designed with the app rather than bolted on afterwards.
