One codebase, both platforms,
without the compromise a lazy shortcut usually implies.
Cross-platform app development builds one shared codebase that runs natively on both iOS and Android, reducing cost and maintenance without sacrificing genuine app quality.
Cross-platform app development uses frameworks like React Native or Flutter to build one shared codebase that compiles to genuinely native apps on both iOS and Android, rather than maintaining two entirely separate codebases in each platform's own language.
Modern cross-platform frameworks have matured considerably, and for the large majority of business app use cases, the resulting app performs and feels genuinely native, with the cost and maintenance savings of a shared codebase.
The right choice between cross-platform and fully native development depends on your specific performance requirements and how deeply the app needs to integrate with platform-specific capabilities, a decision worth making deliberately rather than by default.
Maintaining two entirely separate native codebases, one for iOS and one for Android, roughly doubles ongoing development and maintenance cost compared with one shared cross-platform codebase.
Modern cross-platform frameworks deliver genuinely native performance and feel for the vast majority of business app use cases, making the cost savings rarely come at a meaningful quality cost.
Features and fixes built once in a shared codebase reach both platforms simultaneously, rather than requiring the same work to be done twice, which matters considerably for a fast-iterating product.
How it actually works: Cross-platform app development builds one shared codebase using a framework like React Native or Flutter, compiling to genuinely native apps on both iOS and Android, with platform-specific adjustments made only where genuinely necessary.
A structured process, not a black box.
Framework selection
We select the cross-platform framework genuinely suited to your specific requirements and long-term maintenance considerations.
Shared architecture design
We architect the app around a shared codebase, minimising platform-specific code to only where genuinely necessary.
Native performance optimisation
We optimise for genuinely native-feeling performance and interaction on both platforms, not a noticeably compromised experience.
Platform-specific adjustments
We make deliberate, targeted adjustments where a specific platform's conventions or capabilities genuinely require it.
Testing across both platforms
We test rigorously on both iOS and Android devices, since cross-platform frameworks can still behave subtly differently across platforms.
Deployment to both stores
We handle App Store and Google Play submission for both platforms from the shared codebase.
What's technically involved
- One shared codebase compiling to genuinely native apps
- Framework selection suited to your specific requirements
- Native performance and feel on both iOS and Android
- Targeted platform-specific adjustments where genuinely needed
- Testing across both platforms, not just one
- Simultaneous App Store and Google Play deployment
Related, but distinct.
Cross-platform app development trades a small amount of platform-specific optimisation for meaningfully lower cost and faster iteration compared with maintaining two entirely separate native codebases, a trade that suits the large majority of business apps well.
Common questions
Does a cross-platform app feel noticeably different from a native app?
For most business use cases, no, modern cross-platform frameworks deliver genuinely native performance and feel, with differences typically only noticeable in specific, demanding use cases.
Which framework is better, React Native or Flutter?
Both are legitimate, mature options with different tradeoffs, the right choice depends on your specific requirements, team expertise, and long-term maintenance considerations, not a universal answer.
Does this save genuine cost compared with building separately for iOS and Android?
Yes, typically significantly, since one shared codebase avoids the roughly doubled cost of maintaining two entirely separate native codebases.
Can a cross-platform app still access native device features?
Yes, modern cross-platform frameworks provide access to camera, location, biometrics, and other native capabilities, though with occasional platform-specific adjustment needed.
When should we choose fully native development instead?
When your app has genuinely demanding performance requirements, needs deep integration with platform-specific capabilities, or otherwise has requirements a cross-platform framework cannot meet as well.
