React Native · QalbIT

React Native is not the point. The wait is.

We build with React Native for teams whose users are waiting too long: measured outcomes, written scope, and IP in your accounts.

Nobody asks for React Native. They ask why the dashboard takes four seconds and the form loses their input.

What we build with React Native


React Native development for modern mobile and SaaS-connected products.

We help founders and teams use React Native where it shines: apps that need iOS and Android from one codebase, shared logic with an existing React web app, and a fast path to both stores.

  1. In-app dashboards

    Data-dense mobile screens with lists, filters, charts and role-aware views that stay smooth at scale.

  2. Multi-tenant SaaS companion apps

    Tenant-aware navigation, plan gating and per-account theming shared with your web client.

  3. Customer self-service apps

    Accounts, documents and billing surfaces that cut support volume, on iOS and Android from one codebase.

  4. Design systems in React Native

    A typed component library shared with your web app where the design system allows it.

  5. Migration from native iOS/Android

    Separate native iOS and Android codebases consolidated into one React Native app, screen by screen, without a freeze.

  6. Performance rescue

    Slow, janky or crash-prone apps profiled with Flipper and fixed: measured before and after.

How React Native projects run here


A practical React Native process, from audit to production.

We keep the React Native process structured but lightweight, so we can deliver a working build in real time without surprising you on quality, timeline or budget.

  1. Audit & architecture

    We read the existing code or the requirements, then propose component structure, state strategy and routing.

    Week 1

  2. Component & state design

    A typed component library and predictable state: the decisions that stop a React Native codebase rotting.

    Week 1–2

  3. Implementation & integration

    Build or refactor shared components, wire them to the same APIs your web app uses, and write the native module when a library does not exist yet.

    Sprint by sprint

  4. Testing, hardening & rollout

    Automated tests on critical paths, accessibility and performance passes, then a staged release to both the App Store and Play Store.

    Pre-launch

  5. Ongoing support & features

    A standing team continues to ship features and keeps dependencies current.

    Post-launch

Where React Native earns its keep


React Native use cases we most often deliver.

Most of our React Native work is on consumer and B2B mobile apps that share logic with an existing web product, rather than brochure-ware landing pages.

  • Companion apps for a SaaS product

    The mobile surface of a subscription product: onboarding, workspace access and notifications, sharing code with the web app.

  • Booking & scheduling apps

    Consumer-facing apps for booking, scheduling or ordering, shipped to iOS and Android together.

  • Customer self-service apps

    Accounts, documents, invoices and requests, moved off email and into a shared-codebase app.

  • Native iOS/Android consolidation

    Replacing separate native iOS and Android teams with one React Native codebase, screen by screen.

The stack around React Native


The React Native stack we typically use at QalbIT.

We usually pair React Native with modern tooling: TypeScript, a typed component library and a tested data layer, so the app stays maintainable and predictable as the team changes.

  • Core

    • React Native (New Architecture)
    • TypeScript
    • Expo
    • Metro bundler
  • State & data

    • TanStack Query
    • Zustand / Redux Toolkit
    • REST & GraphQL
    • Zod validation
  • Styling & design systems

    • NativeWind (Tailwind for React Native)
    • React Native Paper
    • Storybook
    • Design tokens
  • Quality & observability

    • Jest
    • Detox / Maestro
    • ESLint & Prettier
    • Sentry

We adapt to what you already run, and share engineers with your existing React web team wherever the roadmap allows it rather than standing up a separate mobile group.

React Native in production


Where React Native is the surface.

The same discipline on every build: typed components, predictable state, and the client owning the code.

Start here


Hire React Native developers who will still be proud of the code in year three.

Share your current front end, goals and the problems you want to solve. We will review your requirements, look at any existing code and propose a practical React Native plan that matches your stage and budget.

  • A written scope with the exclusions listed
  • An architecture recommendation for state and components
  • The name of the engineer who would lead it
  • Free, and yours to keep either way

React Native development: frequently asked questions

Common questions about sharing code with an existing React app, native components, ecosystem size and team setup, plus what happens after launch.

Ask us directly →
When your team already builds in React and JavaScript or TypeScript: the same language, the same component patterns, and often the same engineers can move between your web app and the mobile app instead of learning a new language and toolkit.
Business logic, hooks and data-fetching layers usually move over with little change. UI components do not carry across directly, since React Native renders to actual native components rather than the DOM, but the patterns and the engineers stay the same.
The app inherits the platform’s own look, behaviour and accessibility support automatically, because a React Native button is genuinely a native iOS or Android button under a JavaScript layer, not a redrawn approximation of one.
Usually, yes. React Native has been around longer and draws on the wider JavaScript and npm ecosystem, so most third-party integrations already have a maintained library before we need to write one ourselves.
We write a small native module bridging that one capability from iOS or Android into JavaScript, and keep everything else shared between the two platforms.
Less than you would think. JSX, hooks and state management work the same way in React Native, so a React web engineer is usually productive on the mobile app within days, not weeks, since the language and mental model do not change.
Send us the goal and any existing code. You get a written scope, an architecture recommendation and a price range within 48 hours, free, and yours to keep either way.
