Built your app in FlutterFlow, React or Flutter and now need native iOS or Android features? Start by identifying the product or maintenance problem that SwiftUI or Jetpack Compose would solve.
First, identify what you have
React web renders in a browser; React Native is a separate mobile framework with its own UI. Some business logic or API work may transfer, but web screens do not become SwiftUI or Compose. Identify the current framework before estimating.
FlutterFlow exports a Flutter project as source code. FlutterFlow export documentation.
Treat the export as a Flutter starting point. Scope the engineering work needed for native Swift and Kotlin; assume no one-click conversion.
Flutter compiles Dart to native machine code on mobile, but renders its UI through Flutter’s own framework. Flutter architecture.
A Flutter app can target mobile without using native SwiftUI or Compose controls for its screens. If native appearance, accessibility or system integration is your goal, confirm that need warrants the change.
Choose the smallest path that solves the gap
- Keep the current app if it meets product, quality and support needs. Confirm source, build access and a named owner.
- Audit and refactor when a working app has specific problems: generated code that is hard to maintain, slow releases or costly dependencies. Fix the causes.
- Add a native bridge for a focused platform API. Flutter platform channels let Dart call Swift or Kotlin code. Platform channel documentation.
- Plan a native rewrite only if core flows need native UI or behavior widely enough that targeted fixes no longer work. Compare that scope with keeping the app.
- App meets needs? Keep it
- Specific gaps? Audit and refactor
- One platform feature? Add a bridge
- Core UI needs native? Phase a rewrite
Advance only when evidence shows the earlier option will not solve the problem.
Map what must survive
Before rebuilding screens, list what users and the business rely on: accounts, sign-in, backend rules, purchases and restore, store listings and app IDs, saved data, deep links, push, analytics and consent, permissions, privacy and support. Name an owner for each.
Keep the current store identity and signing in the plan, verified with the account owner. Note which data is server-side and whether local data must move. Include purchase products, transaction validation, account access and restore; the new UI must preserve them.
Migrate in phases around real user flows
- Set a baseline. List critical flows, known defects, supported devices and release process; name each system and account owner.
- Agree parity criteria. Choose initial flows such as sign-in, the core task, purchase and restore, and deep links. Define what must work on iOS and Android before proceeding.
- Build one vertical slice. Implement one valuable end-to-end flow in SwiftUI and Compose, including backend calls and platform integrations. Check it against agreed criteria before expanding.
- Release with an owner. Plan QA, store submission, monitoring and recovery. Hand over repositories, signing and account access, build instructions, operations notes and a named release owner.
Get a quote for a defined scope
A useful quote starts with a review of the app and a written scope. If the evidence is insufficient, agree the scope and cost of a technical assessment first. A full paid audit is not automatically required. The quote should identify flows, platforms, integrations, data work, quality checks, release support, handover and exclusions.
A rewrite is not automatically an upgrade. If the app is reliable and the problem is one integration or release bottleneck, a focused refactor or bridge may suffice. Compare the native vs Flutter guide, React development and Flutter development.
If you are ready to discuss the next step, send the App Store and Google Play links, your current stack and the concrete blocker through native app development or app modernization. We can start with the scope you actually have.
