React Native App Development in London
Expert React Native developers in London building iOS and Android apps for product teams who already think in React — with store-safe releases, not slogan-level “write once”.
React Native for React teams
React Native when your web team should own mobile too
React Native App Development
Native Modules
Expo or Bare — Chosen Honestly
Store-safe Releases
Our work process — from React skills to store binaries
Fit vs Flutter vs Native
Hiring and required native SDKs decide more than hype. We write the recommendation down.
Navigation & Native Look
Not a WebView in a trench coat. Prototypes cover iOS gestures and Android back.
React Native Development
Slices with EAS/TestFlight/Play. Shared types with web where it is honest — not 90% UI share.
Native Gap List
What we write in Swift/Kotlin. Performance on lists. Push on APNs and FCM.
Dual Release
Versioning both binaries. OTA policy written down. Store listings as two jobs.
React Native is a team strategy, not a free iOS app
If you have no React developers, Flutter or native may be cheaper. If you do, React Native can keep one product language across web and mobile. Store hygiene and native modules still exist.Design Dev ships React Native with a native-module budget, CI for both binaries and upgrades planned — React Native versions bite.
- Honest team fit before the first screen
- Navigation that feels like an app
- Native modules listed early
- CI for iOS and Android binaries
- Crash tools on both stores
- Upgrade path as RN versions move
- Store-compliant OTA policy
- Shared API with the React website
Complete React Native capabilities
Cross-platform apps for React-shaped teams — UI, native modules, EAS, two-store release and support under one London team.
React Native App Development
Customer apps on both stores for JS product teams.
Expo App Development
Managed workflow when it fits the SDK list.
Bare React Native
When a required native SDK blocks Expo.
Brownfield / Add-to-App
RN inside existing native codebases.
Native Modules
Swift/Kotlin when JavaScript is the wrong layer.
Shared Design Tokens with Web
Align with React websites where tokens honestly match.
EAS & CI
Repeatable binaries, not laptop builds.
OTA Policy
Updates that stay inside store rules.
Push & Deep Links
APNs, FCM, universal links and App Links.
API with the Web Product
Shared contracts and types — not a second backend by accident.
RN Upgrades
Major versions as a real line item.
Takeover & Untangle
Audit and recover a rushed Expo app.
Ready for React Native because the team is React — not because it is trendy?

React Native across key industries
Healthcare
Appointment, aftercare and clinic apps with careful permissions, secure login and journeys patients can actually finish.
- Clinic apps
- Appointments
- Reminders
- Secure login
A London team that will pick RN for hiring reasons, not Twitter
Design Dev builds React Native when JS product teams should own mobile. Stores and native gaps stay in the plan. We will recommend Flutter or native when that is cheaper.

Product before pixels
Journeys, store rules and backend are planned with the app — not after a demo build.
Platform choice that fits
Native, Flutter, React Native or PWA is a commercial decision, not a trend.
Store-ready delivery
Listings, review, performance and QA on real devices — not a one-off APK email.
Support after launch
OS updates, crashes and iteration once real users arrive.
