Cross-Platform App Development
Building two separate apps doubles your cost and your headaches. We use Flutter to build one codebase that ships natively on both iOS and Android — the same app, both stores, in the same time it would take to build one.

Why cross-platform
Building separate native apps for iOS and Android used to be the only way to get performance that felt right on both platforms. That changed when Flutter arrived. Flutter's custom rendering engine produces pixel-perfect, high-performance UIs that look identical on every device — without writing code twice.
For a founder, the maths are straightforward. A separate iOS and Android build roughly doubles your development cost and doubles the ongoing maintenance burden. Feature updates need to be written twice. Bugs appear on one platform and not the other. Every change requires two rounds of testing.
Cross-platform development with Flutter removes all of that. You ship to both stores simultaneously, maintain one codebase, and update features once. The performance gap between Flutter and fully native has effectively closed for most app categories — consumer apps, fitness platforms, on-demand services, and marketplaces all perform excellently.
Flutter is often a great fit for cross-platform mobile builds, and we have been building with it since before most agencies in Australia caught on. We also build in React Native when it suits the project better. See our dedicated Flutter development page for more detail on the framework, or our React Native page to understand when that's the better call.
What you get
These are the four things every cross-platform build needs to get right. Skip any one of them and you're building a product that will struggle.
You launch on both stores at the same time. No staggered release, no half your market waiting for the other version. One codebase, two live products, submitted and approved together.
Flutter compiles to native ARM code, not a JavaScript bridge. The result is smooth 60fps animations, fast startup times, and a product that feels native on every device it runs on.
Every feature update, bug fix, and design change happens once. One deployment, both platforms updated. Your engineering resources go into building new features, not maintaining parallel codebases.
User acquisition, retention, and engagement tracked across both platforms from launch. You get a unified view of your users regardless of whether they're on iPhone or Android.
How it works
Phase one
We validate your product concept, define the scope, and design every screen before a line of code is written. You see the full product before committing to development.
What you get
Phase two
We build your Flutter app and submit to both stores simultaneously. Weekly demos throughout so you always know exactly where things stand.
What you get
Phase three
One update ships to both platforms at once. We coach you through growth strategy, App Store optimisation, and building the next version from real data.
Industries
Consumer mobile apps where both iOS and Android users matter get the most from a cross-platform build. These are the verticals where we've done it most.
Fitness apps serve both iPhone and Android users in roughly equal measure. Our founder Jarrod built cross-platform fitness apps for creators like Chontel Duncan and Hannah Pearson. A Flutter build means your community does not have to wait for a second platform launch.
Explore fitness appsOn-demand products need to reach every user instantly. Flutter's cross-platform approach means your service provider and customer apps are available on every device, with consistent UX on both platforms from day one.
Explore on-demand appsFood delivery needs a customer app, a driver app, and often a restaurant dashboard — all on both platforms. Flutter makes this achievable without a team of 10 developers. One codebase, multiple user roles, all platforms covered.

Cross-platform development means building a single app that runs natively on both iOS and Android from one shared codebase. Rather than writing separate Swift for iOS and Kotlin for Android, you write once and deploy to both. Flutter and React Native are the two leading frameworks for this, and we recommend based on what fits the project best.
We work with Flutter and React Native, and recommend based on the project. Flutter uses a single rendering engine that produces identical, high-performance UIs on both iOS and Android with excellent animation performance. React Native suits teams in the JavaScript ecosystem or projects extending existing React Native codebases. See our Flutter development page and React Native page to understand when each makes sense.
A cross-platform Flutter MVP in Australia typically costs $50,000 to $80,000. Building once for both platforms is significantly cheaper than building two separate native apps, which would roughly double the development cost. See our cost guide for a full breakdown.
For most app categories, yes. Flutter apps are indistinguishable from native apps in daily use. The gap has closed substantially over the past few years. The main cases where native still has a clear edge are apps requiring very deep platform-specific integrations or specialised hardware access. For consumer apps, fitness, on-demand, and marketplace products, Flutter performs excellently.
From first call to live on both stores, most cross-platform projects take 12 to 16 weeks for a well-scoped MVP. The Inception phase takes 3 to 4 weeks for strategy and design. Development and launch takes another 8 to 12 weeks. You launch on iOS and Android simultaneously.
Yes. Flutter apps meet all Apple App Store and Google Play requirements. We handle the submission process for both stores as part of every build. App Store review typically takes 1 to 3 days. Google Play is usually 24 to 72 hours.
