Flutter apps for iOS and Android from one codebase
Flutter lets one team build an iOS and Android app from a single Dart codebase, with interfaces that look the same on both platforms. It is often the most efficient way for a startup to reach both stores quickly and keep features in sync afterwards. Our team builds Flutter apps with a clear state management approach, writes native platform code when a plugin falls short and tests on real iPhones and Android devices before each release.
What we deliver
Cross-platform app
A single Flutter app delivered to the App Store and Google Play, with platform-appropriate navigation, permissions and system dialogs.
Custom design system
Brand-specific widgets and themes built once and reused across screens, so the product feels designed rather than assembled from defaults.
Native bridges
Platform channels in Swift and Kotlin for features plugins do not cover well, such as specific Bluetooth devices, health data or background tasks.
Backend and real-time data
Integration with Firebase, Supabase or your own API, including authentication, push notifications and offline caching.
Automated builds
CI pipelines that run tests and produce signed builds for TestFlight and Play internal testing on every merge.
How we approach it
When Flutter is the right call
Choose Flutter when you need both platforms at launch, your features are mainly interface, data and standard device APIs, and budget or speed matters more than platform-specific polish.
Native code when it matters
Flutter is not a reason to avoid native work. When a feature depends on deep system access, we write the platform layer in Swift or Kotlin and expose it cleanly to Dart.
Trade-offs stated upfront
Flutter apps are larger than native ones, new OS features arrive through plugins with some delay, and heavy platform integrations add native code anyway. We weigh these against your roadmap before recommending it.

How we work
- 01
Discovery
A short call to understand your goals, users and constraints. You get a clear scope, timeline and estimate.
- 02
Design
User flows and high-fidelity screens that follow Apple’s Human Interface Guidelines — reviewed together before a line of code.
- 03
Build
Iterative development in Swift and SwiftUI with regular TestFlight builds, so you can try the app on your own iPhone as it grows.
- 04
Launch
App Store assets, submission and review handled end to end. Your app goes live under your own developer account.
- 05
Support
Bug fixes, iOS version updates and new features after launch — based on real user feedback and analytics.
Questions
Is Flutter good enough for a production app, or only for MVPs?
Flutter is used for long-lived production apps, not only prototypes. The limits show up in apps that lean heavily on platform-specific features, and we flag those during discovery.
Why Flutter instead of React Native?
Both are capable. Flutter gives more consistent rendering and performance across platforms; React Native can make sense if your team already works in React and TypeScript. We recommend based on your team and product, not preference.
Can a Flutter app use Apple HealthKit or Bluetooth?
Yes, through existing plugins or our own native bridge code. For hardware-heavy products we test the integration early, because that is where cross-platform risk usually sits.
Can we add a web version from the same Flutter code?
Flutter can target the web, and it works well for internal tools and app-like dashboards. For marketing sites or SEO-sensitive pages we usually recommend Next.js instead.
How long does a Flutter MVP take?
Most MVPs take 4 to 8 weeks depending on scope. After a discovery call we give a fixed estimate covering both platforms.
