Devvista is a software development and growth agency that finds, places and manages dedicated mobile engineers and cross-platform app teams, serving clients in the US, UK, Australia, Canada and the UAE. Work is billed hourly, by the team, or as a fixed-price project.
React Native, according to reactnative.dev, brings the best parts of developing with React to native development, and its React primitives render to native platform UI. This page covers what we build, how React Native compares with Flutter, what hiring costs, how to check a developer and how it works from your country.
What our React Native developers build
Mobile apps from your web team's skills
Ordering, booking and account apps where your team already writes React and JavaScript, so people and some logic can move between the website and the app.
Staff tools and inspections
Job lists, checklists, photo capture and approvals for people working away from a desk, with sign-in, roles and a way to keep working when the signal drops.
Apps that sit on your existing systems
A mobile front end for an API, an ERP or a CRM you already run. If the backend also needs work, our dedicated development teams can add that developer alongside.
Device features and native modules
Camera, location, Bluetooth, payments and push notifications, plus the occasional native module when no ready-made library covers a device or an SDK.
Releases and upkeep
Store listings, signing, review responses and later updates, planned as ongoing hours rather than a one-off task.
React Native, Flutter or fully native: which should you hire for?
The table uses each framework's own description, then gives our view. There is no winner, only a better fit for your team and product.
| Point | React Native | Flutter | Fully native |
|---|---|---|---|
| What it is | Brings React to native development; React primitives render to native platform UI (reactnative.dev) | A multi-platform framework from Google that is written in Dart | A separate app for each platform |
| Language | JavaScript | Dart | The platform's own languages |
| Targets | Android, iOS and more, with community projects for Windows, macOS and web | Mobile first, with web and desktop from the same Dart code | One platform per codebase |
| Our view | Best when your team already works in React and JavaScript | Best for new apps that must look the same everywhere | Best when one platform's features are the whole point |

What it costs and how you can hire
Hourly rates for React Native developers run from $10 to $100 by developer level, and fixed prices from $500 to $100,000 by complexity. Quotes are in US dollars.
| Model | Best for | Pricing |
|---|---|---|
| Dedicated React Native developer by the hour | Keeping a live app moving: fixes, updates and new features each month | By developer level |
| Small React Native team | A launch that needs a developer, a designer and a tester working together | Hourly, per person |
| Fixed-price build | An app whose screens and rules are written down before work begins | By complexity |
| Scoping first | You have a goal and users but no screen list or backend plan yet | A short engagement that ends in a written spec |
Illustration (an estimate, not a quote): a customer ordering app with accounts, push notifications and a payments flow, at an assumed $40 an hour:
| Work | Hours |
|---|---|
| Discovery and written spec | 18 |
| Navigation and screens from the approved design | 70 |
| Accounts and API connection | 50 |
| Payments flow | 40 |
| Push notifications | 24 |
| Automated tests | 36 |
| Store release setup | 28 |
| Launch and handover | 14 |
| Total | 280 hours, about $11,200 at $40 an hour |
Drop the payments flow and the total falls; add integrations and it climbs. A screen list from you is all we need to price your own version.
Which React Native developer profile you need
Mobile work calls for different strengths as the app matures, so choose the profile that fits where you are.
| Profile | What they do | Ask to see |
|---|---|---|
| App developer (JavaScript and React) | Builds screens and navigation, manages state and talks to your API | A shipped app and the reasoning behind its structure |
| Native module developer | Writes platform code where a library falls short of a device feature or SDK | A module they wrote and how they tested it on devices |
| Mobile technical lead | Organises a larger codebase so several people can work in it without collisions | A repository layout and a release routine |
| Release and QA engineer | Tests on real devices and carries the app through store review | A checklist and examples of review feedback they resolved |
Common situations and what to hire
Which arrangement suits you depends on where the app is today.
| Your situation | What to hire | Why |
|---|---|---|
| No app yet, only an idea and some users | A short scoping engagement, then a fixed-price build | The screen list and the backend plan come first, so the build has something to be priced against |
| A live app with a growing list of fixes | A dedicated developer by the hour | Steady hours keep releases regular without a project plan for each fix |
| A web team that wants to add a mobile app | A small team with one lead from us | Your React skills carry over, and we add the native and release experience |
What the first month of a React Native hire looks like
- Week one: access to the repository, a test device list and a written scope, with the first screen chosen together.
- Week two: the first screens running on real iPhones and Android phones, shown to you on a working build.
- Week three: the API connection and the states users hit most, such as loading, empty and error.
- Week four: a review of what was built against the spec, a test run on devices, and an agreed plan for the next stage.
How to check any React Native developer before you hire
Whoever you shortlist, these six checks separate people who have shipped from people who have only studied.
- How is shared state handled in this app, and what would you change if it grew tenfold?
- Where do iOS and Android behave differently, and how do you handle that in code?
- When is a native module worth writing instead of using a library, and who maintains it later?
- Which devices and operating system versions will you test on before release?
- Who holds the store accounts and signing keys, and how is access handed over?
- What will the app cost each month once it is live, beyond the build?
- Ask for a small paid trial task before you commit: a single screen with navigation, one API call and one test, reviewed together.
If a quote arrives before anyone has asked about your systems, the quote is a guess.
Mistakes to avoid when hiring React Native developers
Most disappointing mobile hires come down to a handful of avoidable choices.
- Hiring for a framework before agreeing the screens, so the estimate has nothing to rest on.
- Skipping real-device testing and finding platform differences in store review instead.
- Leaving store accounts and signing keys in the developer's name.
- Treating launch as the finish line and budgeting nothing for updates.
Hiring from the US, UK, Australia, Canada and the UAE
Devvista works remotely with clients in the US, UK, Australia, Canada and the UAE and has no office in any of them. You will see progress on a board and in regular demos, wherever you are.
Who this is for, and who it is not
| A good fit | Not a fit |
|---|---|
| A company that wants an iOS and Android app and can list the screens | A request to guarantee downloads, ratings or a launch date before scope exists |
| A team with React and JavaScript skills that needs extra mobile capacity | A project that depends on developers being in your office |
| Owners ready to approve a written spec and look at working builds each stage | A basic web page that a website builder or WordPress would handle more cheaply |
