Mobile App Development
For iOS & Android
Cross-platform apps built once with React Native — native performance on iOS and Android, App Store and Google Play submission included, ongoing maintenance available. UK-wide service from West Sussex.
What Goes Into Every App
Every mobile app I build ships with these capabilities as standard — not bolted on later as expensive add-ons.
Cross-Platform From One Codebase
Native iOS and Android apps built once in React Native or Expo. Half the cost of building two separate apps, with near-native performance and feel.
App Store + Google Play Submission
Full submission handled end-to-end — App Store Connect setup, Google Play Console setup, screenshots, store listings, privacy compliance, and the review process.
Push Notifications & Native Features
Push notifications, offline mode, camera, GPS, biometrics, in-app purchases — all the native device capabilities your app needs to feel like a first-class citizen.
Shared Backend With Your Website
Your app can plug into the same backend as your existing website — one database, one source of truth, lower hosting costs and easier maintenance.
Secure & UK GDPR-Aware
Secure authentication, encrypted data, proper handling of user permissions, and architecture designed with UK GDPR in mind from day one.
Fast Iteration & OTA Updates
Over-the-air updates with Expo mean you can ship bug fixes and improvements without waiting for App Store review. Real-time iteration with your users.
How I Build Apps That Last
Apps need to survive yearly OS updates, dependency upgrades, and changing store policies. I build them to survive all three.
Native Performance
I build with React Native and Expo so apps feel as fast and responsive as native apps — without the cost of maintaining two separate codebases.
Store-Ready From Day One
I follow Apple and Google guidelines from the start. No surprise rejections, no last-minute scramble to fix policy issues before submission.
Built To Update
iOS and Android both release major OS updates yearly. I architect apps so OS updates and dependency upgrades are routine, not painful migrations.
Real-User Testing
TestFlight and Google Play internal testing let real users try your app before launch. I set up the full testing flow so you ship with confidence.
Mobile App vs Web App: Which Do You Need?
Not every business needs a mobile app. The honest answer for many is a fast, installable web app (PWA) is enough. But there are clear signals you actually need a native app:
Push notifications matter
If re-engaging users with timely alerts is core to your model, native apps deliver this far better than web.
Offline mode is critical
Field workers, transport, hospitality — anywhere connectivity is unreliable, native apps work where web apps stall.
App Store presence builds trust
For consumer-facing brands, a polished App Store listing is a credibility signal that web alone can't match.
You need native device features
Camera, GPS, biometrics, Bluetooth, NFC, in-app purchases — these are smoother and more reliable in a native app.
Not sure which fits? I'm happy to talk through your use case before any commitment — sometimes a Progressive Web App is the smarter starting point.
