React Native App Development
Cross-platform iOS and Android apps from one React Native codebase, with a native feel and shared business logic underneath.
React Native Apps
One Codebase. Two Platforms.
One React Native codebase, both app stores, a native feel on each. We've been building software since 2008 as WebNX Global Services, with clients spanning the US, UK, Canada, India and beyond.

Why cross-platform
Building two native apps the hard way?
If any of these sound familiar, one React Native codebase solves it, without the compromises that come from a cheap wrapper.
06 reasons teams move from two native apps to one
- 01
Paying twice to build the same app
Two native apps means two codebases, two teams and a bill that is roughly double. React Native ships iOS and Android from one codebase, so you build the thing once and it works everywhere.
- 02
iOS and Android quietly drifting apart
Maintain two native apps separately and features land on one platform weeks before the other. A single React Native codebase keeps both platforms perfectly in step, every release.
- 03
A cross-platform app that feels cheap
A badly built React Native app lags and feels off, and users notice instantly. Built properly, with native modules bridged in where it matters, it is smooth and indistinguishable from native for almost everyone.
- 04
Release cycles that move too slowly
Pushing a fix through two native apps takes days of store review on each. React Native with over-the-air updates lets most changes reach users instantly, no review queue involved.
- 05
No in-house mobile specialists
If your team already knows React and JavaScript, they can maintain a React Native app too. You are not forced to hire and manage separate Swift and Kotlin specialists just to keep the lights on.
- 06
Needing native features without native lock-in
Worried cross-platform cannot handle a camera, payments or Bluetooth properly? React Native bridges to native modules, giving you full platform capability without maintaining two entire codebases.

React Native version upgrades, dependency updates, OS readiness and new features that keep the app current long-term.
Why choose us
React Native done the right way
React Native is genuinely brilliant when built well and disappointing when it is not. We know the difference: real native components, native modules bridged in where they count, and the new architecture used properly. These are the standards behind every app we ship.
Start your project-
Build once, ship to both
One codebase for iOS and Android cuts cost and time significantly, without the compromises that come from a cheap wrapper app.
-
Genuine React Native specialists
We know the framework in depth, including the new architecture, native modules, and the specific traps that make a bad RN app feel bad.
-
Native feel, never a web view
We build with real native components and bridge to native modules exactly where it counts, so the app feels right on both platforms.
-
Updates that ship instantly
Over-the-air updates let us fix and improve the app without waiting days for a store review to clear.
-
Any native capability you need
Camera, biometrics, Bluetooth, payments, maps. If the platform can do it, we can bridge to it.
-
Code sharing with your web app
If you already run a React web app, we share logic and components to keep your whole product consistent and efficient to maintain.
-
Tested on both platforms, always
We test on real iOS and Android devices, because one shared codebase still needs verifying on each platform separately.
-
We keep React Native current
React Native moves quickly. We handle version upgrades and dependency updates so your app never quietly falls behind.
How we work
Our React Native development process
Eight clear stages, each with something you can see and sign off on. No black box between idea and both app stores.
- 01
Discovery
We map your users, target platforms and any native capabilities the app is going to need.
- 02
Design
Platform-aware UI designed and prototyped, then signed off by your team before build begins.
- 03
Architecture
App structure, state management, native modules and backend planned out up front.
- 04
Development
One React Native codebase built in sprints, with a build for both platforms every week.
- 05
Testing
Real-device testing across iOS and Android, backed by Jest and Detox automation.
- 06
Submission
We build, sign and submit to both the App Store and Google Play, handling each review.
- 07
OTA Setup
Over-the-air updates configured so every future fix can ship the moment it is ready.
- 08
Support
React Native upgrades, monitoring and new features, well after the app is live.

Client words
Trusted by teams shipping to both stores
We needed iOS and Android on a startup budget, and React Native got us onto both stores from one codebase in ten weeks. It feels native, our own React developers can maintain it, and over-the-air updates let us iterate daily. Exactly the right call for us.
They migrated us off two separate native apps that were constantly out of sync with each other. Features now ship to both platforms at once and our maintenance cost has roughly halved. The native module work for our barcode scanner simply worked, first try.
The app is fast and our users genuinely cannot tell it is cross-platform. They handled the new architecture migration and the performance is native-grade in practice. Shipping fixes over the air without waiting on review has been a real game changer for us.

Questions, answered
React Native app development FAQs
How much does a React Native app cost?
The cost depends on the app's features, design, backend and native requirements. React Native can reduce development effort by sharing code across iOS and Android, while complex apps with custom native modules require more work. Every project is scoped and quoted individually.
Is React Native as good as native?
For most apps, yes. React Native renders real native components and, with the new architecture and native modules bridged in where needed, performs smoothly and feels genuinely native. For extremely graphics-intensive apps or deep platform-specific features, fully native may still edge it, and we will tell you honestly if that applies to your project.
How long does React Native development take?
A focused React Native app typically takes eight to sixteen weeks to cover both platforms, faster than building two native apps separately would take. You see builds for both platforms every week as the project develops.
Why choose React Native over native?
One codebase for both platforms means lower cost, faster delivery, and features that stay perfectly in sync across iOS and Android. It also lets a React or JavaScript team maintain the app going forward. Choose native instead when you need maximum performance or deep platform-specific capability throughout. We advise honestly based on your actual needs.
Can React Native access device features like camera and Bluetooth?
Yes. React Native bridges to native modules, so it can use the camera, Bluetooth, biometrics, GPS, payments, push notifications and essentially any device capability, either through existing libraries or custom native code we write for you.
What are over-the-air updates?
Over-the-air updates, delivered via EAS Update or CodePush, let us push JavaScript changes directly to installed apps without going through App Store or Play review. Bug fixes and many features reach users instantly instead of waiting days for approval.
Do you handle both store submissions?
Yes. We build, sign and submit to both the App Store and Google Play, and manage each review process so the app launches on both platforms together, not weeks apart.
Can you share code with our React web app?
Yes. We can share business logic, state management and even some components between a React web app and your React Native app, keeping your product consistent and cutting down on duplicated work.
Should I use Expo?
Expo speeds up development, simplifies builds and makes over-the-air updates easy, and it now supports custom native code through development builds too. We use Expo for most projects and bare React Native when a project has unusual native requirements. We pick whichever actually fits.
Can you take over an existing React Native app?
Yes. We audit the existing codebase, upgrade the React Native version, fix outstanding issues and add new features. Outdated RN apps are common, and they are very fixable.
How do you keep up with React Native upgrades?
React Native releases regularly and its dependencies move fast. On a maintenance plan, we handle version upgrades and dependency updates so your app stays current and never becomes hard to change.
What happens after launch?
Every project includes a handover and a warranty window. Most clients move onto a maintenance plan covering React Native upgrades, OS readiness, monitoring and new features, so the app stays healthy well past launch.
