    React Native's core advantage goes beyond "one codebase for two platforms": the codebase is React, which means your web team's skills, component patterns, and even shared business logic carry over to mobile with far less relearning than a fresh framework demands. For teams that already have a React web app, that overlap compounds: shared validation logic, shared API clients, sometimes shared UI components via a monorepo.

    Where React Native earns its keep

    React Native bridges directly to native APIs (camera, GPS, biometrics, Bluetooth) so you're not limited to a web-view wrapper pretending to be an app. The New Architecture (Fabric + JSI) closed most of the historical performance gap with fully native apps for typical CRUD and list-heavy screens; it's genuinely competitive for consumer and B2B apps that aren't pushing real-time graphics or heavy computation. Expo's OTA update channel means bug fixes and minor feature changes can ship without an App Store review cycle, a meaningful advantage when you're iterating fast post-launch.

    Expo or bare workflow?

    We default to Expo's managed workflow for new projects: it handles build tooling, OTA updates, and most native module needs without ejecting, which shortens setup time significantly. We move to the bare workflow only when a project needs a native module Expo doesn't support or a build configuration outside Expo's defaults (custom native SDKs, specific background processing requirements). That decision gets made in discovery, not discovered mid-build.

    Why React Native

    Why React Native?

    JavaScript / TypeScript Codebase

    Built on React - the world's most popular UI framework. Your web and mobile teams can share skills, components, and logic across platforms.

    Native Module Access

    React Native bridges directly to native APIs - camera, GPS, biometrics, push notifications, and Bluetooth - giving you full platform capability without separate native code.

    Fast Iteration

    Hot reloading means instant feedback during development. New React Native architecture (Fabric + JSI) delivers near-native performance for complex apps.

    OTA Updates with Expo

    Push JavaScript updates to your users without App Store review cycles using Expo OTA - fix bugs and ship features faster than any native app.

    Comparison

    React Native or Flutter?

    React Native is ideal for teams with JavaScript/React expertise and projects needing OTA updates. Flutter offers superior rendering control and pixel-perfect UI. We help you pick the right tool for your product.

    How we work

    Our React Native Delivery Process

    1. 01

      Discovery & Architecture

      We map your feature set, decide on Expo (managed) vs bare React Native workflow, and set up TypeScript, navigation, and state management before writing screen code.

    2. 02

      Shared Component Build

      We build a shared component library first (buttons, forms, lists) so screens compose from tested primitives instead of one-off implementations.

    3. 03

      Native Module Integration

      Camera, GPS, biometrics, and Bluetooth are wired through vetted native modules; anything without a mature package gets a small custom native module rather than a shaky workaround.

    4. 04

      Testing, OTA Setup & Store Submission

      Jest and Detox tests run in CI on every PR. We configure Expo OTA channels for post-launch updates, then handle App Store and Google Play submission.

    FAQ

    Frequently Asked Questions

    React Native is the better choice if your team has JavaScript or React web experience, if you need a large ecosystem of community packages, or if you plan to share logic and components between your web and mobile apps. Flutter delivers better out-of-the-box animation smoothness and visual consistency. Both produce production-quality apps: the decision usually comes down to your existing tech stack and team skills.

    A React Native MVP for iOS and Android typically takes 8–14 weeks from wireframe to App Store submission. Apps with real-time features, complex animations, Bluetooth integrations, or payment flows add 4–8 more weeks. We deliver in two-week sprints with working demo calls so you are never waiting to see progress.

    Yes. We migrate native Swift, Kotlin, or Objective-C apps to React Native, typically using a hybrid approach where we replace screens incrementally while keeping the existing native shell. This avoids a full rewrite and lets you continue shipping to users while the migration is in progress.

    A React Native MVP typically runs $22,000–$40,000 over 8–14 weeks. A growth-stage app with real-time features, animations, and Bluetooth or payment integrations runs $40,000–$80,000 over 14–20 weeks. Enterprise builds needing custom native modules or complex system integrations start at $80,000. Every quote is fixed-scope after a free discovery call.

    We default to Expo's managed workflow because it covers OTA updates and most native module needs without the maintenance overhead of managing native build configs directly. We only move to bare React Native when a project needs a native module Expo does not support, or a build setting outside Expo's defaults. This gets decided during discovery, before the codebase is structured around either choice.

    Yes, TypeScript is our default for all new React Native builds. It catches prop-type and API-shape mismatches at compile time rather than in a simulator, which matters more on mobile where a crash means a bad App Store review, not just a console error. We'll work in plain JavaScript if a client's existing codebase requires it, but we always recommend migrating incrementally.
