What React Native development actually is

One React codebase that renders true native UI on iOS and Android

React Native lets a React and JavaScript team build both apps from one codebase, with the UI rendering as real native components, not a web view.

React Native · one codebaseApp.tsx · COMPONENT TREESafeAreaViewFlatListPressable<Text> · <Text> · <Text>Fast RefreshSAME APP · NATIVEiOSAndroidReact + JSX · ExpoNative components, not an engineOne React codebase. iOS and Android, native.

One JavaScript codebase

A React team writes the app once in JavaScript or TypeScript and ships it to the App Store and Play. No separate Swift and Kotlin builds.

True native UI

The screen renders real native views, not a web wrapper, so scrolling, gestures and navigation feel like the platform, not a website.

Expo and OTA updates

Expo and Fast Refresh speed the build, and over-the-air updates push small fixes straight to users without waiting on a store review.

React Native, or fully native

When React Native earns the build, and when it does not

React Native wins when a React team and one codebase matter most; native wins when polish or new APIs are the product. We tell you which, before the build.

Fully native (Swift + Kotlin)Two builds, two teamsReact NativeOne codebase, both stores
CodebaseTwo separate codebases, one per platform, built and maintained apart.One JavaScript codebase ships to the App Store and Play together.
Speed to launchSlower and pricier: two builds to write, test and submit.Faster: one team, Fast Refresh, and OTA updates after launch.
Polish and APIsFull day-one access to every platform API and the finest polish.Native on most apps; the last 10% and newest APIs need a native module.
Best forApps where feel sells, or that lean hard on new device hardware.Startups, MVPs and React teams that need both stores on a budget.
Not sure which you need?

If you want one codebase for the App Store and Play, React Native is usually the call. For a Dart codebase with the same one-team economics, see Flutter app development. If the feel is the product, see iOS app development. We help you decide in the first conversation.

How we build for React Native

Built for the startup that needs both stores, fast and on budget

For an Indian startup, the slow and costly part of mobile is building twice.

  1. 01of 04
    Time to marketBoth stores, one team

    A startup that has to build twice ships late and spends twice.

    React Native lets one React team ship iPhone and Android from a single codebase, so the MVP reaches users and investors on a startup timeline, not a year out.

    Our methodOne codebase, both stores, on a startup timeline.
  2. 02of 04
    JS talent in IndiaHire and scale

    JavaScript and React talent is the deepest hiring pool in India.

    Because the app is React, the team that builds it is the team you can later hire from, in Bangalore, Pune or anywhere. The skill is common, so the app is not stranded.

    Our methodBuilt on the most available skill set in the market.
  3. 03of 04
    Mid-range AndroidPerformance discipline

    Most of India is on mid-range Android, not flagship iPhones.

    We profile lists, images and navigation on real budget devices, and drop to a native module where a screen needs it, so the app stays smooth where the users actually are.

    Our methodTuned and tested on real mid-range Android.
  4. 04of 04
    You own itIP and no lock-in

    Your code and your store accounts are company assets.

    Your repo, your App Store Connect and Play Console, full IP and a clean handover, so the app is something you control and can move, not something tied to us.

    Our methodFull IP, your store accounts, clean handover.

Why React Native

React Native builds native iOS and Android apps from one React codebase, sharing skills and logic with the web.

How we excel

We build in React Native so the app shares code and a team with the web, which is ideal when a client already has a React web product to align with.

Our commitment

Our commitment, in writing

A React Native build goes wrong when it lags on mid-range Android, when it gets stuck at a store review, or when the IP is unclear. We build against all three.

  • You own the IP

    Your repo, your App Store Connect and Play Console, and full IP, with a clean handover. The app is your asset, not ours.

  • Tuned for real devices

    Profiled and tested on real mid-range Android, not just an iPhone simulator, so it stays smooth where your users are.

  • Built to pass both reviews

    Built to the App Store and Play review guidelines on privacy, payments and data, so the first submission is the one that ships.

  • A senior team, named

    Senior React Native engineers on your build with one accountable lead, not a rotating junior bench.

Your app is your asset: code, both store listings and all.
