What does a freelance React Native developer actually deliver?
A freelance React Native developer writes your app once in JavaScript or, better, TypeScript, and produces two native apps from it: an Android build for Google Play and an iOS build for the App Store. The buttons, lists and text inputs are real platform components, not a web page inside a wrapper, so the app feels native to users.
React Native is open source and maintained by Meta with a large community around it. Its big advantage for businesses is familiarity: the component model, hooks and state patterns are the same ones used on React websites. A company that already runs a React or Next.js site can hand the app to its own web developers later with far less retraining than a Kotlin or Swift codebase would need.
The deliverable is more than screens. A complete React Native project includes the navigation structure, API calls to your backend, login, push notifications, analytics, crash reporting, app icons and splash screens, store listings and the signed release builds. In our team one of us leads the app and API code, another of us handles cloud hosting and any data or AI features, and the third of us plans releases and testing rounds.
When is React Native the right framework, and when is it not?
React Native is the right call when your product is mostly forms, lists, feeds, bookings, payments and content, which describes the large majority of business apps. It is a strong fit when you already have JavaScript developers, a React website, or a Node.js backend, because types and logic can be shared.
It is a weaker fit for heavy 3D games, apps that process live video frames, or products whose main feature is a brand-new platform capability the day Apple or Google announces it. In those cases native code, or a game engine, avoids fighting the framework.
Choose React Native when
You want Android and iOS together, your team knows React, the app talks to web APIs, and you may later hand maintenance to web developers.
Choose Flutter when
No one on your side writes JavaScript, you want pixel-identical custom UI on both platforms, and Dart is acceptable for future hires.
Choose native Kotlin or Swift when
Only one platform matters, or the app depends on deep device features, background processing or graphics performance.
Android-only projects are covered on Kotlin development, and iPhone-first ones on iOS development.
Expo or bare React Native: what a freelance React Native developer should recommend
For new apps, start with Expo. It is the framework the React Native team itself recommends for new projects, and it removes most of the setup pain: builds in the cloud through EAS Build, store submission through EAS Submit, file-based routing with Expo Router, and a large library of maintained modules for camera, notifications, location and secure storage.
An old worry was that Expo locked you out of custom native code. That is no longer true. With development builds and config plugins, you can add any native library or your own Kotlin and Swift modules while keeping Expo’s tooling. You still own a normal React Native project and can eject from managed services at any time.
Bare React Native, managing the Android and iOS folders by hand, still makes sense for some brownfield cases, such as adding React Native screens inside an existing native app. For everything else, we choose Expo because it keeps upgrades simpler, and upgrades are where React Native apps usually age badly.
- EAS Build: signed Android and iOS builds without a local Mac for every developer
- EAS Update: ship JavaScript fixes to users without a full store review, within store rules
- Config plugins: native settings stay in code, not hand-edited project files
- Development builds: test custom native modules on real devices
Native modules: what happens when JavaScript is not enough
Sooner or later most serious apps need something outside the standard toolkit: a payment provider SDK, a Bluetooth printer, a biometric device, a background location rule, or a vendor library shipped only for Android and iOS. That is when a freelance React Native developer has to write native code.
Since React Native’s New Architecture became the default, modules talk to JavaScript through JSI and TurboModules rather than the old asynchronous bridge, which is faster and type-checked. In practice we write most new modules with the Expo Modules API, in Kotlin for Android and Swift for iOS, with a small TypeScript interface your app code calls like any other function.
Before starting, check whether a maintained library already exists and whether it supports the New Architecture. An unmaintained wrapper is technical debt that shows up during the next upgrade. When we do write a module, it lives in your repository with tests and a short readme, so it is never a black box.
Common reasons for native work
Printer and scanner SDKs, UPI intent handling through your payment provider’s SDK, background uploads, home-screen widgets, and deep integration with device settings.
Question to ask any candidate
“Show me a native module you wrote and explain how the JavaScript side calls it.” Vague answers suggest they only assemble libraries.
How do you vet a freelance React Native developer?
Install their apps. A live listing on Google Play or the App Store tells you more than any CV. Open a published app on an older Android phone, scroll a long list, rotate the screen, switch to airplane mode and back. Crashes, frozen lists or a blank screen offline are all visible within five minutes.
Then talk about the unglamorous parts. Ask how they handle React Native version upgrades, how they manage signing keys, and who owns the Apple and Google accounts. Ask what state management they use and why; a thoughtful answer might be “server state in TanStack Query, small local state in Zustand or context”, while “Redux for everything” with no reason is a yellow flag, not a disqualifier.
Finally, request a small paid first milestone, such as the login flow and one real screen on a test build. You will see their TypeScript, their commit habits and how quickly they respond to feedback before committing the full budget.
- Published apps you can install, not only screen recordings
- TypeScript used throughout, with typed API responses
- A clear upgrade and signing-key plan
- Store accounts and repository in your name from day one
- Crash reporting and analytics included in the scope
- Test builds shared through TestFlight and a Play internal testing track
How much does a freelance React Native developer cost in India?
With BtechWaleTech, a React Native app for both Android and iOS starts at ₹40,000 (US$600 for overseas clients), and a first release typically takes 6–10 weeks. That starting point covers a focused app: login, a handful of core screens, an API connection, push notifications and store publishing.
Across the market, quotes for a React Native app spread widely. Some quote only the screens and leave out the backend, store setup or admin panel; others include everything. The honest comparison is scope against scope. When a quote is far below the rest, check whether it includes the server, the database, the release process and support after launch.
If your app needs a larger backend, such as multi-vendor ordering, dispatch or accounting, that part is scoped like custom software, which starts at ₹60,000. Detailed budgeting by complexity is on app development cost in India and freelance rate comparisons on freelance app developer cost.
What changes the price of a React Native app
Most of the cost of a React Native app sits outside the screens. These are the lines that move a quote.
Backend depth
Using an existing API is cheapest. Building a new server, database and business rules is often half the work.
Native features
Anything beyond Expo’s modules, such as a custom printer SDK or background tracking, needs Kotlin and Swift time on both platforms.
Offline mode
Letting users work without signal means local storage, sync rules and conflict handling. Worth it for field staff, overkill for most shoppers.
Admin panel
Staff need a web screen to manage orders, users and content. A simple panel is modest; a reporting dashboard is more.
Design
Using a clean component system is quick. Fully custom motion and illustration takes design and build time.
How long does a React Native app take to build and publish?
Budget 6–10 weeks for a first release. Simple content or booking apps land near six; apps with payments, a new backend and native modules take longer. Store review adds a few days at the end, and Apple’s first review of a new app can take longer than later updates.
We work in short cycles you can hold in your hand. After scoping and screen designs, you get a test build within the first few weeks through TestFlight on iPhone and an internal testing track on Android. Each week after that, a new build arrives with the next set of features.
One timing detail catches many first-time app owners: Google currently requires newly created personal Play developer accounts to run a closed test with a group of testers for about two weeks before production access. If you register as an organisation this does not apply the same way. We plan for it at the start so launch day does not slip.
Publishing a React Native app: accounts, signing and store review
Your app should be published under your name, not the developer’s. That means you create a Google Play Console account and an Apple Developer Program membership, pay the registration fees directly, and add us as users with the permissions needed to upload builds.
Signing keys deserve special care. On Android, Play App Signing holds the app signing key with Google, and an upload key sits with your project. On iOS, certificates and provisioning profiles live in your Apple account. If a developer keeps these privately and disappears, updating your app becomes painful. We document where every key lives and share credentials through your own password manager or accounts.
Store review is predictable if you prepare. Both stores want a privacy policy link, accurate data-safety or privacy labels, working demo credentials for reviewers, and no misleading screenshots. For a detailed walkthrough of account ownership, see choosing a mobile app developer.
Most Indian users will open your app on a mid-range or budget Android phone, often on patchy mobile data. A React Native app that feels smooth on a new iPhone can stutter there unless it is built with that phone in mind.
The Hermes engine, now the default, helps with start-up time and memory. The rest is discipline: virtualised lists (FlashList or a well-tuned FlatList) for long feeds, images resized on the server instead of the phone, animations run on the UI thread with Reanimated, and no heavy work during the first screen render. We test release builds, not debug builds, on low-RAM devices and throttled networks.
App size matters too, because many users have little free storage. Android App Bundles let Google Play deliver only what each device needs, and trimming unused libraries keeps the download light. For wider context on building for Indian phones, our Android app for Indian customers page goes deeper.
Sharing code with your React website and handing the app to your own JavaScript team
This is the reason many businesses pick a freelance React Native developer over other options: the app does not have to become a separate island. TypeScript types for your API, validation rules, date and currency formatting, and data-fetching hooks can live in a shared package used by both the website and the app.
Screens themselves are usually written separately, because a phone screen and a desktop page solve different problems. But the logic underneath, such as what counts as a valid order or how a discount is applied, stays in one place, so a rule changed for the website changes in the app too.
If you plan to take maintenance in-house later, tell us at the start. We will keep the structure conventional, write a setup guide that gets a new developer running a build on day one, and walk your team through the codebase before handover. See React development for the web side of the same stack.
Updates, upgrades and maintenance after your React Native app launches
A React Native app is never truly finished. Apple and Google raise their minimum SDK and target requirements every year, React Native itself ships regular releases, and libraries move on. Apps that skip upgrades for two years often need a painful catch-up project.
Plan for three kinds of change. Quick JavaScript fixes can go out through EAS Update, within the stores’ rules on over-the-air code. Feature releases go through normal store review. Platform upgrades, such as a new React Native version or Android target level, are done a few times a year and tested properly.
Our two months of free maintenance after release covers bug fixes, small changes and keeping builds healthy. After that, maintenance starts at ₹8,000/mo and is optional; the code and accounts are yours, so your own team or another developer can take over. For apps that stopped building after years of neglect, we also take on upgrade rescue work as a quoted project.
Red flags when hiring a React Native freelancer
Most React Native projects that go wrong show it early. Pause before paying an advance if you see any of these.
- The app will be published on the developer’s own store account “for now”
- No test build for weeks, only screenshots or screen recordings
- Plain JavaScript with no types on a project meant to last years
- Dozens of unmaintained libraries added for small features
- No answer about signing keys, upgrades or the New Architecture
- Backend, hosting or admin panel left vague in the quote
- Promises of guaranteed downloads or top store ranking
Good developers answer these points without being asked. If you already have an app built this way, it is usually fixable: accounts can be transferred and code cleaned up, though it is cheaper to start right.
Example scenario: a salon chain’s booking app
This is a hypothetical example to show how a freelance React Native developer would scope a real-world app; it describes no actual client.
A salon brand with a handful of branches already runs a React website with an online booking form. Customers keep asking for an app with reminders and loyalty points. The owner wants one app for Android and iPhone, and hopes the web developer on staff can maintain it later.
Version one would include phone number login with OTP, branch and stylist selection, slot booking against the same API the website uses, UPI and card payment, reminder notifications a day before, and a loyalty balance. A shared TypeScript package would hold booking rules so the site and app agree. Built with Expo, released to both stores in the owner’s accounts, it would sit on the ₹40,000 plan with payment and loyalty lines itemised, over roughly eight weeks.
Left for version two: stylist portfolios, product sales and referral codes. The owner’s web developer would join the last two weeks for a guided walkthrough of the code.
