Cross-Platform App Development
One codebase, every platform — iOS and Android
Cross-platform app development lets you reach iOS and Android users simultaneously without the cost and complexity of maintaining two separate native codebases. Using React Native and Flutter, we build apps that feel native on both platforms, sharing the majority of code while still delivering platform-appropriate experiences. It's the smart way to launch on mobile when budget and speed to market matter.

What this service solves
Clear reasons to choose this work, based on what your business needs.
01
Reduced Development Cost
A shared codebase typically reduces development cost by 30 to 50% compared to building separate native apps for each platform.
02
Faster Time to Market
Build once and deploy to both platforms simultaneously, getting your app into users' hands faster than a dual native approach.
03
Native-Like Performance
React Native and Flutter compile to native code, delivering smooth animations and interactions that feel genuinely native.
04
Simpler Maintenance
Bug fixes and new features are written once and deployed across both platforms, halving your ongoing maintenance overhead.
05
Code Reuse
Up to 90% code sharing between iOS and Android reduces technical debt and ensures feature parity between platforms.
06
Wide Platform Coverage
Some frameworks also support web and desktop targets, allowing you to extend your app's reach beyond mobile in the future.
What is included
The exact scope is agreed in your written quote before work starts.
React Native Development
JavaScript-based cross-platform development with a large ecosystem, strong community, and proven track record at scale.
Flutter Development
Google's Flutter framework delivers beautiful, performant apps with a rich widget library and consistent cross-platform rendering.
Platform-Specific Adaptations
Navigation patterns, UI components, and interactions adapted for each platform so the app feels truly at home on iOS and Android.
Native Module Integration
When cross-platform libraries don't cover a requirement, we write native modules in Swift/Kotlin to bridge the gap.
Over-the-Air Updates
CodePush (React Native) and Shorebird (Flutter) for deploying JavaScript or Dart updates without App Store submissions.
Push Notifications
Cross-platform push notification systems using Firebase Cloud Messaging that work consistently on both iOS and Android.
App Store & Google Play Submission
We manage submissions to both stores simultaneously, handling the distinct requirements of each platform's review process.
Performance Profiling
Frame rate analysis, memory profiling, and bundle size optimisation to ensure your app performs well on lower-end devices.
How the work runs

Frequently Asked Questions
Should I build a native app or cross-platform app?
For most business applications, cross-platform is the pragmatic choice — it delivers an excellent user experience at lower cost. Native development is better when your app requires deep platform integration (ARKit, watchOS, health sensors), maximum performance (complex gaming, real-time processing), or when your team already has dedicated iOS and Android expertise.
Is React Native or Flutter better?
Both are excellent choices. React Native suits teams with JavaScript expertise and benefits from a large ecosystem. Flutter is often praised for more consistent cross-platform rendering and strong animation performance. We'll recommend the right one based on your project, your team's existing skills, and your long-term technology strategy.
Will my cross-platform app feel native to users?
Yes, when built properly. Modern cross-platform frameworks render using native components (React Native) or their own high-performance render engine (Flutter). The key is following platform design conventions, which our designers and developers do by default.
Can a cross-platform app access the camera, GPS, and other device features?
Yes. Both React Native and Flutter have well-maintained libraries for camera, GPS, biometrics, accelerometer, Bluetooth, and most other device capabilities. In the rare case a library doesn't exist, we write native modules in Swift or Kotlin to provide the functionality.
What is the difference in performance between cross-platform and native apps?
For most applications, the performance difference is imperceptible to users. React Native and Flutter are used by major companies including Facebook, Alibaba, BMW, and eBay for production apps serving millions of users. Only the most demanding applications — complex games, real-time audio processing — might justify the additional cost of native development.
