Take your no-code or AI-generated prototype from Base44, Lovable, FlutterFlow, Bolt, or Bubble through to a production-ready native iOS and Android app. Flutter and React Native specialists.
You validated your idea in Base44, Lovable, FlutterFlow, or Bolt. Users are signing up, the feedback is positive, and you are ready to grow. Then you hit the wall: Apple rejects your submission under Guideline 4.2 (Minimum Functionality), Apple StoreKit demands a native payment flow that your WebView cannot deliver, your app shows a 3 to 5 second white screen on launch while the JavaScript bundle loads, or a potential enterprise client asks about offline mode and your no-code platform simply cannot provide it.
This is not failure. It is the moment your product outgrows its prototype tooling. In our experience working with founders who reach this point, the cleanest projects are the ones where the team accepts the transition early rather than fighting it with brittle WebView wrappers for another six months. We help you cross over without throwing away the work you have already done.
The signal that vibe-coded MVPs no longer scale tends to come from one of five places:
If you recognise any of these, you are not stuck. You are at the normal transition point for products built this way.
Native does not automatically mean starting from scratch. The right answer depends on which platform you built on and what you are trying to achieve.
FlutterFlow apps are in the best position. FlutterFlow exports real Flutter and Dart code. A specialist Flutter team can take that export, refactor the architecture, strip out proprietary FlutterFlow widgets, migrate state management to BLoC or Riverpod, extend it with native device APIs, and submit it to the App Store. You keep the UI work and business logic already completed. The salvage rate is high.
Lovable, Base44, and Bolt apps are built on React, Vite, and Tailwind CSS. React Native shares the component model, hooks, and state management patterns with React, but it does not use the DOM. Web tags like div and span have no equivalent in React Native: they correspond to View and Text components that wrap real native UIViews and ViewGroups. Business logic, REST API calls, Supabase configuration, and data-layer code can typically be ported rather than rewritten. The UI layer is rebuilt against React Native primitives, but the core of your product transfers.
Bubble apps export no source code. The pragmatic path is to treat Bubble's database and workflows as a REST API that a new native frontend calls. Your front-end is built fresh in Flutter or React Native, but your data model, user accounts, and workflow logic stay in place. The unit-economics problem above usually means moving the heaviest API calls off Bubble onto a thin Supabase or Firebase layer at the same time.
Base44, Glide, Adalo, and other AI-generated web apps vary. The codebase itself is rarely salvageable, but design tokens (colour palettes, typography, API schemas) port cleanly, and Firebase or Supabase backends connect directly to a new native client.
In every case, the work starts with a scoping exercise (our App Gameplan) before any code is written. That is how you avoid paying for a rebuild you did not actually need.
Apple's App Store Review Guideline 4.2 (Minimum Functionality) exists to keep the App Store from filling up with wrapped websites. Reviewers are explicitly trained to look for native screen transitions, native scroll behaviour, native gesture handling, and integration with operating-system features (notifications, Sign in with Apple, App Tracking Transparency prompts that fire correctly before any analytics, biometric authentication). A Capacitor-wrapped Lovable build is detectable in seconds and rejected on the first submission attempt.
Apple's policy on payments is stricter still. Guideline 3.1.1 requires apps that deliver digital goods or services to use Apple StoreKit for the purchase, with a 30% commission for the first year and 15% thereafter. Reader apps, web-to-app billing flows (covered in our web-to-app billing 2026 explainer), and external link entitlements offer routes to reduce that, but the default starting position is that every digital purchase goes through StoreKit. Google Play Billing applies a similar regime on Android.
Apps built from sprint one with these guidelines as constraints pass first-time review at a noticeably higher rate than apps retrofitted at the end. We treat compliance as a structural requirement, not a launch-week checklist.
If you are not sure whether you need a full native rebuild, a partial migration, or a hybrid approach, the App Gameplan is built for exactly this decision.
In 4 weeks, for a fixed fee of £3,500, we map your existing product against your growth goals and produce a board-ready plan: what to build natively, what to keep on your current platform, what the native build will cost, and a realistic timeline. The fee is credited in full if you proceed to development with us.
Why this matters: when founders survey UK agencies, they tend to receive quotes ranging from £5,000 (a wrapper plus minor fixes) to £60,000 (a clean-room rebuild) for the same project, depending on whether the agency wants to upsell a full rewrite or downscope to a quick wrapper. The Gameplan exists so you can walk into those conversations with a written specification that pre-empts both extremes.
We build in Flutter and React Native, and we have shipped production apps in both since their respective production releases.
The Gameplan recommendation lands on one of these based on the specifics of your project, your team's existing skills, and your roadmap. We do not default to whichever framework happens to fill our current capacity.
A condensed view of what transfers and where each source platform hits its ceiling, drawn from our review work with founders coming from each tool.
From the projects we have audited or rebuilt in the last 18 months, three patterns stand out:
Going native is not a one-time project. App Store policy updates, OS version changes, new device form factors, App Tracking Transparency changes, and evolving privacy requirements mean your app needs ongoing attention. We offer App Support packages for post-launch maintenance, and our team stays available for the feature iterations that come after your first native release.
Written by Gareth Reese, Founder and CTO of Foresight Mobile. Gareth has been shipping production mobile apps since 2007 (mobile games via Chillingo and Crystal SDK) and leading Flutter delivery since 2017, including maintenance of flutter_markdown_plus, used in over 140,000 Flutter apps per week.
An actionable four-week plan with clear deliverables and an unbeatable £3,500 price point, credited against your first development sprint.

Alongside this, we prioritise features based on business value and technical complexity, mapping out a phased delivery plan with a detailed cost estimate.
You receive your complete Gameplan pack, plus a presentation walkthrough with Q&A. Your team walks away with everything needed to make a confident decision.
Why founders pick us for the vibe-to-native transition
The App Store is not a one-time event. OS updates, new device form factors, privacy requirement changes, and the inevitable first feature iteration all need a team that knows your codebase. Our App Support packages keep a skilled mobile team available for ongoing maintenance and development. You are not scrambling to find someone to fix a crash the week after a major iOS release.
We have shipped production apps in Flutter and React Native since both frameworks reached production maturity. We are a listed partner in the FlutterFlow Experts directory, and our Flutter portfolio spans consumer apps, enterprise tooling, and apps used by professional sports teams. We will tell you which framework is right for your project rather than defaulting to whichever one happens to fill our current capacity. The recommendation is grounded in your existing code, your team's skills, and your roadmap.
Apps built specifically for App Store compliance pass first-time review at a noticeably higher rate than apps retrofitted at the end. We treat Apple's App Store Review Guidelines (4.2 Minimum Functionality, 3.1.1 Payments, 5.1 Privacy) and Google Play's developer policies as design constraints from sprint one, not a launch-week checklist. That means native StoreKit and Google Play Billing flows, correct entitlements for push notifications and biometrics, App Tracking Transparency prompts firing in the right order, and UI that is genuinely native rather than a polished WebView.
Going native does not mean discarding your existing product. For React-based apps (Lovable, Base44, Bolt), we port business logic, hooks, and REST API code to React Native rather than rewriting it. For FlutterFlow apps, we continue from the generated Flutter codebase after refactoring. Your user data, accounts, and back-end integrations stay in place. The native app connects to what you already have, often via Supabase, Firebase, or a thin REST API layer in front of your existing database.
Before any native code is written, you commission an App Gameplan: a 4-week, £3,500 scoping engagement that produces a board-ready technical plan, cost estimate, and timeline. You will know exactly what to build natively, what to keep on your current platform, and what the full project will cost. The fee is credited against development if you proceed with us. UK agency quotes for the same vibe-to-native project routinely vary by 10x, and the Gameplan anchors the conversation to an actual specification.
We have built with and reviewed codebases from Base44, Lovable, FlutterFlow, Bolt, and Bubble. That means we can give you a straight assessment of what carries forward and what needs a rebuild, rather than defaulting to "start from scratch" to protect project scope. FlutterFlow exports in particular are clean enough that we can take your generated Dart code and extend it natively without throwing away the UI work already done.
Post-launch support is handled via our App Support retainer (App Care), which most clients move onto at launch. App Care covers iOS and Android release compatibility (annual SDK targeting, Privacy Manifests, App Tracking Transparency changes), crash triage with full Sentry or Firebase Crashlytics observability, and a defined response window: business-day response on standard issues, four-hour response on App Store breakages. If you do not take an App Care retainer, we offer a 30-day post-launch warranty on any defects introduced during our build (excluding feature changes you commission after sign-off).
You own everything from day one. Source code is delivered to your GitHub or GitLab organisation, not ours, at the start of the engagement, and every commit is on your account. The original vibe-coded source (FlutterFlow export, Lovable build, etc.) remains yours throughout. Our standard contract assigns all IP in the new native build to you on payment of each milestone, and we sign an NDA at the start of the App Gameplan if there are sensitive features or stakeholders involved. Authentication credentials, App Store Connect access, and any backend API keys stay in your accounts; we use scoped delegation rather than shared logins.
The same assessment process applies. Glide and Adalo apps generally need a full native rebuild (they generate proprietary runtime code that does not export). Webflow is a website builder that ships as a wrapped web app and runs into the same Apple Guideline 4.2 problem as Lovable and Base44 when packaged for the App Store. Softr sits on top of Airtable and works as a web product; for a native app, we treat the Airtable base as the database and build a fresh Flutter or React Native frontend against the Airtable API or a thin Supabase mirror. In every case, the existing data, brand assets, and business rules transfer. The codebase rarely does.
It can, but watch the unit economics. Bubble's Workload Unit pricing was designed for web traffic patterns, and a native frontend tends to make API calls far more aggressively (background refresh, optimistic mutations, foreground polling). We have seen WU consumption increase fivefold within weeks of a native launch. The pragmatic answer for most projects is to leave Bubble's workflows in place where they are working, but move high-frequency endpoints (auth, lists, search) onto a thin Supabase or Firebase layer at the same time as the native build.
That risk usually exists already, and the native migration is the right moment to fix it. AI-generated web apps frequently bundle sensitive logic into the front-end JavaScript, and reverse-engineering a mobile wrapper exposes that immediately because the bundled JS sits in the IPA or APK. During a native rebuild, we move secrets and business logic to server-side functions or to authenticated edge functions (Supabase Edge Functions, Firebase Cloud Functions, or Cloudflare Workers), and the mobile client only ever sees scoped API responses.
All major vibe-coding and no-code platforms: Base44, Lovable, FlutterFlow, Bolt, Bubble, and others. We are a listed partner in the FlutterFlow Experts directory. What we care about is your existing product and what it needs. The platform it was built on is a starting point for the technical assessment, not a constraint on whether we can help.
Yes, end to end. We manage Apple Developer account setup, provisioning profiles, App Store Connect configuration, screenshot production, App Privacy details, content rating, App Tracking Transparency declarations, and review responses if the app is flagged. Most apps we submit pass first-time review. When they do not, we handle the response and resubmission. We have been submitting apps across both stores since 2017 and have submitted apps coming from no-code and AI-generated source code in 2025 and 2026 specifically.
The App Gameplan (£3,500 fixed, 4 weeks) is the right starting point if you are not yet sure what you need. It produces a full project specification and cost estimate so you can make an informed decision before committing to development. UK agency quotes for vibe-to-native transitions vary wildly (£5,000 for a wrapper to £60,000+ for a full rebuild) for the same source project, so the Gameplan exists in part to anchor the conversation around an actual scope. Native migration projects with us typically start from £25,000 for a focused MVP feature set. Projects with complex back-end integrations, real-time features, or extensive native device APIs are larger. The Gameplan fee is credited in full if you proceed to development with us.
If you are coming from FlutterFlow, Flutter is the clear choice (your existing code carries forward). If your existing codebase is React-based (Lovable, Base44, Bolt), React Native lets your developers stay in a framework they know and lets you share business logic, hooks, and TypeScript types between your web and mobile apps. If you are starting fresh with no existing code to port, Flutter gives a marginally better native performance profile via Impeller and a more consistent cross-platform UI; React Native gives a larger npm ecosystem and tighter integration with web tooling. Both are production-proven. The App Gameplan includes a specific recommendation for your project.
Typically 10 to 20 weeks from App Gameplan completion to App Store release, depending on existing product complexity and how much native functionality is required. FlutterFlow migrations sit at the faster end because the Flutter codebase is already there. Lovable and Base44 projects with significant feature sets take longer because the UI layer is rebuilt from scratch against React Native primitives. The Gameplan deliverable includes a specific timeline for your project, not a range.
Apple's App Store Review Guideline 4.2 (Minimum Functionality) states that apps must offer some unique functionality that elevates them beyond a repackaged website, and rejects apps that are primarily web content rendered in a UIWebView or WKWebView. Wrapper tools like Capacitor, Cordova, and Ionic can pass review when the app integrates genuine native features (StoreKit IAPs, APNs push, biometrics, hardware access), but pure WebView shells with no native integration are consistently rejected. Reviewers test for native gesture handling, native screen transitions, the absence of text-selection highlighting on buttons, and correct App Tracking Transparency prompt ordering. Enforcement has tightened through 2024 and 2025.
Your user accounts and data stay exactly where they are. The native app connects to your existing back-end, so users log in with their existing credentials and see their existing data. For apps migrating from platforms without an API layer (some Bubble configurations, for example), we build a lightweight REST API wrapper as part of the project so the native app can talk to your existing database without requiring a data migration. Authentication flows usually migrate to Supabase Auth, Firebase Auth, or Auth0 depending on what your back-end already uses.
Yes. FlutterFlow generates real Flutter and Dart code that a Flutter specialist team can work with directly. We export the project, audit the generated code, refactor proprietary FlutterFlow widgets out, migrate state management to BLoC or Riverpod, and continue development from that point. This is often significantly faster than a greenfield build because the UI scaffolding and Firebase integration are already in place. The main work is strengthening the data layer, adding native device integrations (background tasks, push notifications, biometrics), and setting up a proper CI/CD pipeline for App Store and Play Store submission.
You need native if your roadmap includes any of the following: App Store or Play Store distribution, in-app purchases through Apple StoreKit or Google Play Billing, reliable background push notifications via APNs or FCM, background location tracking, Bluetooth or NFC hardware integration, FaceID or TouchID biometric authentication, offline-first data sync with local persistence, or sustained performance beyond what a WebView can deliver at scale. If none of these apply, your no-code platform may serve you for longer. A one-hour scoping call is usually enough to tell the difference, and the App Gameplan produces a written answer with the supporting analysis attached.
Not necessarily. FlutterFlow projects export real Flutter and Dart code that a specialist team can refactor and extend without rewriting. Lovable, Base44, and Bolt apps are React-based, and React Native shares enough with React that business logic, hooks, and REST API code typically port rather than discard. Bubble apps export no code, so the front-end is rebuilt, but the database, workflows, and user data stay intact behind a REST API. The App Gameplan scoping engagement is built specifically to identify what carries forward before you commit to any development spend.
Most vibe-to-native projects follow the same four-phase pattern. We start with the App Gameplan to establish exactly what needs to be built natively. From there, a technical audit of your existing codebase identifies what carries forward and what needs replacing. The native build follows a sprint-based delivery model with regular demos, and we manage the App Store submission from first upload to approval. Most clients stay on an App Support package after launch for ongoing maintenance and feature development.
