React Native App Development
React Native suits teams already living in JavaScript. It renders real native components, shares logic with your web product, and keeps one language across the stack.
The short answer
What is react native app development?
React Native builds Android and iOS apps from one JavaScript or TypeScript codebase, rendering actual native platform components rather than drawing its own. Apps therefore inherit native controls, gestures and accessibility behaviour by default.
Its real advantage is organisational. If you already have React on the web and a team that writes TypeScript, React Native lets the same people ship mobile, and lets validation, types, API clients and business logic be shared instead of reimplemented.
Scope
What we build
Cross-platform apps
Android and iOS from one TypeScript codebase.
Companions to a React web app
Sharing types, API clients and business logic with an existing product.
Content and commerce apps
Feed-driven and catalogue-driven products that suit native list rendering.
Business and internal tools
Operational apps with offline capability and role-based access.
Brownfield integration
Adding React Native screens inside an existing native app.
Expo projects
Managed workflow where it fits, with a clear path out if it stops fitting.
Why teams call us
Business problems this solves
If more than two of these describe your situation, the problem is usually structural rather than cosmetic.
- A React web team that cannot ship mobile
- Validation and business logic reimplemented per platform and drifting apart
- Two native codebases, one team
- Slow release cycles because every fix ships twice
- An app that should feel native but was built to look identical everywhere
- An old React Native app stuck on an unsupported version
How it works
Our process
- 01
Fit assessment
Whether React Native suits this product and this team — including when it does not.
- 02
Shared-code plan
What can genuinely be shared with your web product, and where the boundary should sit.
- 03
Architecture
Navigation, state, data fetching, offline behaviour and native module boundaries.
- 04
Build
TypeScript and React Native, with component and end-to-end tests.
- 05
Dual-platform QA
Real hardware on both platforms, since native rendering differs between them.
- 06
Release
Store submission, over-the-air update strategy where appropriate, monitoring.

How we think about it
Our approach
Design approach
Because React Native renders real platform components, apps feel native without extra effort — and diverge between platforms in ways you have to design for. We treat that as an advantage: navigation, dialogs and typography follow each platform's conventions while the brand layer stays shared. Users get something familiar; you still get one codebase.
Performance and security
The performance work in React Native is specific and well understood: keep the JavaScript thread free, use native driver animations through Reanimated, virtualise long lists properly, and avoid re-rendering trees on every state change. The New Architecture removes much of the old bridge overhead. We profile with Flipper and Hermes and test on mid-range Android hardware.
Budget
What drives the cost
We do not publish price ranges, because a number given before we understand the work is not a real one. These are the factors that actually move it.
- Number of screens and user roles
- How much can genuinely be shared with an existing web codebase
- Native modules required for anything outside the ecosystem
- Expo managed workflow versus a bare project
- Offline and synchronisation complexity
After a discovery conversation we give a fixed scope and a fixed number before any work begins.

Services that go with this
Mobile App Development
Android and iOS applications, plus the backend, APIs and admin tooling that make them work. Built once in Flutter or React Native where that suits the product, natively where it does not.
Flutter App Development
One codebase, both platforms, and an interface that renders identically on each. Flutter suits products where the design is your own rather than the platform's.
Custom Software Development
Internal platforms, portals, dashboards and workflow tools modelled on how your operation actually runs — not on how packaged software assumes it should.
Hire Developers
Dedicated developers and extended teams for startups, agencies and product companies — with the working model, code ownership and handover agreed in writing before anyone starts.
Questions
React Native App Development — frequently asked
React Native or Flutter?
React Native if your team already writes React and TypeScript, or you want to share code with a web product — the organisational fit usually outweighs the technical comparison. Flutter if you want a custom design rendered identically on both platforms. Both are production-grade.
Should we use Expo?
For most apps, yes — it removes a lot of build tooling pain and now supports custom native code through development builds. We avoid it when a project needs unusual native integration from day one, and we always keep the exit path open.
How much code is actually shared with our web app?
Realistically: types, validation, API clients and business logic — often a meaningful portion of the non-visual code. Components generally are not shared, because a web layout and a mobile layout should not be the same thing.
Can React Native apps be updated without a store release?
JavaScript-only changes can ship over the air, which is useful for fixes. Anything touching native code still requires a store release, and both stores have rules about what may be changed this way.
Is React Native still a reasonable choice?
Yes. It is used at scale in production by large consumer apps, and the New Architecture addressed the main historical performance criticism. It is a mature choice, not a bet.
Can you upgrade our old React Native app?
Usually. Version upgrades across several major releases are real work, particularly with unmaintained dependencies, so we assess first and give you an honest comparison against a rebuild.
