Cross-Platform App Development in Flutter & React Native
Flutter and React Native apps for products where one codebase is the right call — designed, engineered, and finished to the same standard as our native work.
Cross-platform is not the discount aisle of app development. Done properly, it is an engineering choice with real advantages and real limits: one codebase can be exactly right for an internal tool, a content-led product, or a budget that has to cover both stores well — and exactly wrong for a product whose roadmap quietly assumes native-grade depth. We build with Flutter and React Native as well as Swift and Kotlin, so when we recommend a stack, it is advice about your product, not a pitch for the only tool we own.
One codebase
both stores served by a single team and one release rhythm
Honest advice
a stack recommendation grounded in your product, not our pipeline
Native at the seams
platform channels and native modules where the framework ends
When one codebase is the right call
The honest case for cross-platform is not "cheaper native" — it is a different set of trade-offs that genuinely suits certain products. We help you make the call on evidence: what the interface demands, how deep the device integration runs, who your team can hire, and where the roadmap points in two years.
- Internal and operational tools, where iteration speed beats platform ceremony
- Content- and forms-led products whose interface maps cleanly to shared components
- A budget that must cover iOS and Android well, rather than one platform twice
- Validation-stage products that need to test the market on both stores at once
Flutter, built properly
Flutter earns its reputation when it is treated as its own discipline, not a shortcut. We write disciplined Dart, keep widget trees shallow and rebuilds intentional, and reach through platform channels to native code where the product needs what the framework does not carry. The result renders at the device's refresh rate and behaves like it belongs there.
- Dart with sound null safety and a state approach chosen per product, applied consistently
- Widget and rebuild discipline so lists stay smooth on mid-range hardware
- Platform channels to Swift and Kotlin where native capability is the point
- Platform-aware navigation, typography, and gestures — not one UI stamped on both
React Native, built properly
React Native suits teams with JavaScript fluency and products that live close to the web. We build on TypeScript and the framework's modern architecture, keep the bridge out of hot paths, and write native modules where the ecosystem's plugins stop short — the same native skills we use daily, pointed at the seams.
- TypeScript throughout, with the New Architecture as the default for new work
- Navigation, gestures, and animation running on the UI thread, not across the bridge
- Native modules in Swift and Kotlin where a package does not exist or does not hold up
- Hermes, bundle discipline, and startup budgets measured like any native app
How we choose between Flutter, React Native, and native
The stack decision is the most expensive one in a mobile project, and it deserves better than ideology. We walk it with you against the things that actually decide it: interface depth, device capability, team shape, hiring plans, and where the product needs to be in three years. Because we build all three, the recommendation carries no hidden commission — and when the evidence says go native, we tell you that too.
The same bar as our native work
A shared codebase is not an excuse for a shared-lowest-standard experience. Cross-platform builds here go through the same design states, the same senior review gates, the same profiling on real mid-range devices, and the same store-release discipline as every native app we ship. One codebase, both stores, no discount tier.
- Every state designed: loading, empty, offline, error — same as our native process
- Performance profiled on representative hardware, not just the development machine
- Senior engineering review on every pull request
- App Store and Play Store launch handled end to end, with staged rollouts
Every engagement includes
- Native architecture planning before code
- Senior developer review on every pull request
- App Store & Play Store launch support
- 3 months of free post-launch support
Frequently asked questions
Flutter or React Native — which should we choose?
It usually falls out of your team and your product rather than the frameworks themselves. React Native suits organisations with strong TypeScript and web experience and products that share logic with a web app; Flutter suits teams starting fresh who want one rendering pipeline and highly custom UI. We will recommend one for your case and say plainly why.
Will a cross-platform app feel native to users?
It can get close when someone sweats the details: platform-correct navigation and typography, gestures that track the finger, and performance held to a budget on real devices. That is how we build. The remaining gap matters for some products and not at all for others — telling you which yours is, honestly, is part of the job.
Can you take over an existing Flutter or React Native codebase?
Yes. We start the same way we do with native takeovers: a structured review of architecture, dependencies, performance, and release health, then a plan ranked by payback. Where a problem is a framework limit rather than an implementation issue, we say so and cost out the options rather than quietly rebuilding.
When would you tell us to go native instead?
When the app is the product and competes on feel, when the roadmap leans on deep device work — camera pipelines, background processing, platform-specific capability the year it ships — or when a decade-long product life makes the platforms’ own languages the lower-risk foundation. We build both, so that advice costs us nothing to give.
What happens when we need a feature the framework doesn't cover?
We write it natively and expose it to the shared codebase — platform channels in Flutter, native modules in React Native, in the same Swift and Kotlin we use every day. Products only get stuck at the framework boundary when nobody on the team can cross it; here, crossing it is routine.
