React Native mobile app development
We build cross-platform mobile apps with React Native and Expo — a single codebase that ships polished, performant experiences on both iOS and Android. If you already have a web backend, we integrate directly with it; if you don't, we build one. We handle native modules, push notifications, offline support, app store submissions, and everything in between. No context-switching between two separate native codebases — just one senior team shipping a product that feels native on every device.
Everything in the engagement
Cross-platform iOS & Android app
A single React Native codebase shipping to both platforms, with platform-specific polish where it matters for user experience.
Backend & API integration
Seamless connection to your existing web backend, or a purpose-built mobile API if you're starting from scratch.
Authentication & secure storage
Biometric auth, secure token storage, OAuth flows, and session management handled correctly for mobile.
Push notifications
FCM and APNs integration, notification scheduling, deep-linking, and in-app notification centres.
App store submission
We handle the full submission process for both the Apple App Store and Google Play — certificates, metadata, screenshots, and review responses.
Offline support & performance
Local state management, optimistic updates, and offline-first patterns so the app works well even on poor connections.
Our approach
Diagnose — we review your existing product, target users, and any existing backend before scoping the mobile build.
Plan — screen flows, API contract, and feature prioritisation agreed in writing before development starts.
Build — working builds delivered to TestFlight and the Play Store internal track throughout development, not just at the end.
Ship — production builds submitted, reviewed, and live on both stores.
Support — OTA updates via Expo, post-launch bug fixing, and optional retainer for ongoing releases.

Frequently asked questions
Why React Native instead of Flutter or native Swift/Kotlin?
- If you already have a web product built in React or Next.js, React Native lets us share logic, types, and team context across platforms. For most product apps it ships 90% of the native experience at a fraction of the cost of two separate native codebases.
Can you build a mobile app to match our existing web app?
- Yes — we do this regularly. We audit the web product, identify the core mobile use cases, and build a focused app that complements rather than duplicates the web experience.
How long does a React Native app take to build?
- A focused MVP with core flows, auth, and API integration typically takes 8–12 weeks from kick-off to App Store submission. Scope, complexity, and third-party dependencies all affect that range.
Do you handle app store rejections?
- Yes. We handle the full submission process and respond to review feedback. We design the app to meet App Store and Play Store guidelines from the start, which minimises rejections.
Can we update the app without a full store submission each time?
- For UI and JS changes, yes — Expo's OTA update system lets us push updates instantly. Native module changes always require a new store submission.
