Your native iOS app and Android app are two separate codebases. One is always broken.
When separate native iOS and Android development becomes too expensive and too slow for your team size, React Native lets you maintain a single codebase that ships to both platforms. We rebuild mobile apps in React Native when it makes sense — fixed scope, fixed price.
You're maintaining separate iOS and Android apps with separate developers. iOS ships a feature, Android gets it 6 weeks later. A bug is fixed on one platform and persists on the other for months. You're spending twice the engineering on mobile as you should be.
Separate native iOS and Android development is the right approach when the apps need to do genuinely platform-specific things — complex custom hardware interactions, platform-specific gestures, deeply integrated OS features. For most mobile applications — the kind that display data from an API, handle user authentication, process payments, and provide a feature-rich UI — the platform-specific requirements are small and the shared logic is dominant. In that case, separate native codebases impose a 2x cost on every feature shipped and a 2x opportunity surface for bugs.
The divergence problem compounds over time. iOS and Android apps start with feature parity at v1.0. By v2.0, there are small differences. By v3.0, the differences are large enough that the apps are providing genuinely different user experiences — not because anyone decided that was the right product decision, but because iOS features didn't get ported to Android and vice versa. Users who switch platforms (from Android to iPhone or back) notice the difference and complain.
The economics are clear: at most startup and scale-up team sizes, you cannot justify two parallel mobile engineering tracks. A React Native rebuild that produces a single shared codebase isn't always the right answer — there are cases where native performance requirements make React Native the wrong trade-off — but for the majority of business applications, it's the right approach and the rebuild pays for itself within the first year of reduced engineering cost.
A single React Native codebase that ships to iOS and Android simultaneously, eliminates platform divergence, and lets your team maintain one set of features rather than two — without sacrificing the native performance your users expect.
Feature parity across both platforms
Everything the iOS app and the Android app currently do, combined into a single React Native application. Platform divergences are identified and resolved during the rebuild — you decide which platform's implementation to standardise on for each divergent feature.
Shared business logic
Authentication (Clerk), API calls, state management, offline sync, and payment processing (Stripe) are implemented once and shared across platforms. No more shipping the same feature twice.
Platform-specific UX where it matters
Navigation patterns, modal behaviour, and gesture handling that feel native on each platform — not a one-size-fits-all UI that feels wrong on both.
Push notifications
Expo Push Notification service for cross-platform notification delivery. Notification scheduling, segmented delivery, and user preference management.
App Store and Play Store submission
Production builds, metadata, screenshots, and submission for both stores. Certificate management and code signing. Built on React Native, Expo, TypeScript, Clerk, Convex or REST API backend.

Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Why Fixed-Price Matters Here
Mobile app rebuilds have a defined scope: the existing iOS and Android apps are the specification. Feature parity plus improvements is a scoped deliverable. Fixed scope, fixed price.

React Native is the wrong choice for: apps with complex real-time graphics (games, AR), apps that need deep OS-level integration (system-level services, complex background processing), or apps where the user base expects platform-native design patterns so strictly that a shared UI would feel wrong. For most business and consumer applications, React Native performance and UX quality is indistinguishable from native for end users.
React Native apps use native platform components for rendering — the performance profile is native for most UI interactions. The JavaScript bridge (or the new React Native architecture using JSI) handles business logic. For standard mobile application patterns, users cannot distinguish React Native from native performance.
Yes — React Native has platform-conditional rendering for features that need to behave differently on each platform. Platform-specific code is a small percentage of a typical React Native codebase and doesn't undermine the shared-codebase efficiency advantage.
A React Native rebuild of a functional iOS + Android app pair typically runs $45k–$90k depending on feature complexity. Push notifications, offline sync, and payment integration are common additions. Fixed-price.
