REACT NATIVE DEVELOPERS
React Native is what we use when budget, speed and quality all have to live together. One codebase runs across iOS and Android, the app just feels right, its performs quickly. and updates cleanly. We’ve used it to build products that rely on live data, secure transactions, and constant iteration without increasing dev time or cost.
We deploy proper unit and regression testing, version control, waved releases, as well as performance tracking built in as our standard. Based in London and Surrey, we work hands-on with teams and ship React Native apps across the UK and beyond, the same focus everywhere: reliability, adoption, and performance that lasts.

What Success Looks Like
When it’s built right, nobody asks what it’s built in. It just works, opens quickly, scrolls clean, doesn’t crash. That’s what we call success. Not on launch day, but six months later when it’s still running fast and updates go out without a fight.
Problems We Solve
Most of the “React Native problems” we see aren’t React Native problems at all. They’re architecture problems. Forked codebases. Slow API calls. Missing version control. Front-end glued together with no plan for growth.
We rebuild the foundations, proper state management, modular design, CI/CD sorted, analytics wired in.
We Optimise
We track crash rates, cold-start times, conversion paths, and retention curves because that’s where growth hides. As usage climbs, we tighten the code, monitor load, and ship improvements weekly.
You’ll know what changed and why. The app stays lean, your team keeps momentum, and you never fall behind platform updates again.

REACT NATIVE MOBILE APP DEVELOPERS
What We Build
Strategy-first builds: We start with how the product will be used and what it needs to achieve — mapping users, goals, and data flow before a single line of code. That stops bloat and keeps the roadmap clear.
Modular code, lean logic: Every build uses clean, reusable components so new features slot in without breaking what’s already working.
UX-led development: Designers and developers should sit together. they care about tap sizes, loading states, and flows that feel natural.
Native where it matters: Some features, camera, GPS, payments do require native access, for these features we build in Swift or Kotlin so nothing feels compromised.
Post-launch evolution: Once it’s live, we track real usage, crash logs, funnels, drop-offs, and ship small updates instead of waiting for a big version bump.
REACT NATIVE APP DEVELOPMENT
How We Deliver It
Strategy-first builds: We start with your users, business model, and success metrics, then architect the app around them. No bloated features, no over-engineering.
Modular code, lean logic: We build clean, efficient codebases designed to scale, adapt, and stay maintainable, even as your team or roadmap evolves.
UX-led development: Design and engineering work hand-in-hand. We focus on intuitive navigation, responsive layouts, and interfaces that guide users toward action.
Native integrations when needed: We don’t force-fit React Native everywhere. Where it matters, camera, GPS, payments, we use native modules to ensure performance.
Post-launch evolution: Once live, we don’t vanish. We monitor performance, gather insights, and help you iterate fast with new features, A/B tests, and smart updates.
WHAT MAKES REACT NATIVE UNIQUE
Our Point of View
We use React Native because it gets products moving quicker. One team builds for iOS and Android at the same time, so you can reach your users sooner and you can learn from them faster. Speed to market is everything, each week saved brings feedback and traction forward.
It’s not about cutting cost; it’s about adding value. One codebase means you’re not paying twice to do the same thing. Updates take hours, not days, and maintenance stays light.
And when your product grows, it grows cleanly. Add features, plug in APIs, rebuilding nothing.
FAQS
Questions were asked before we are hired
How do you start a React Native build?
We ask questions, lots of questions . What’s broken now? What’s non-negotiable? Who’s using it first? Until we understand that, there’s no point opening Xcode or Android Studio. Then we map data flow, APIs, and the edge cases that usually get missed. Once that’s nailed, we spin up the repo and get a working build running fast.
Is React Native fast enough for real apps?
Yeah, when you build it right. The slow ones you’ve seen usually mix bad state handling with lazy optimisation. We trim bundle size, keep render cycles lean, and use native modules for the heavy lifting, camera, maps, video. It runs near-native speed but deploys twice as fast. Most users can’t tell it’s not a fully native build.
Can you fix our existing app?
Usually, yes. We start by reviewing what’s already there, the repo, build setup, and dependencies. Most problems come from years of bolt-ons and no version control discipline. Sometimes it’s faster to rebuild clean than patch bad code. Either way, we’ll tell you straight. React Native’s modular, so we can drop in new features or replace the broken bits without nuking the whole thing.
How long does a build usually take?
Depends how clear the brief is. A small MVP might take eight to ten weeks if we’ve got access to everything early. Bigger products with integrations, logins, and payments take longer. We move quickly, but we don’t rush architecture. Once design, API, and data are locked, the rest flows quick. React Native helps, one shared codebase for iOS and Android keeps the timeline tight.
Can you work with our internal team?
Yes we have done it many times. We’ve dropped into plenty of in-house setups where there’s already a backend or design team in place. We just bring the React Native layer, app structure, build pipeline, release management. We’ll slot into your stand-ups, share repos, keep everything visible.
How do you handle testing?
We test as we build, as well at the end. Unit tests catch logic bugs early, integration testing checks API calls behave under load, and real devices tell us what simulators miss. React Native’s hot-reload and staging builds mean fixes ship by sprint, not in big releases. It keeps regressions low and feedback loops short.
What happens after launch?
We stay close. Monitor crash reports, track adoption, look at what people are actually doing in the app. We patch, optimise, and roll out small updates . React Native makes this easy, one release hits both stores at once.
Can you add React Native to an existing app?
Yes, you don’t need to start again. We can slot React Native alongside your existing native code and migrate feature by feature. It’s how most teams modernise without breaking production. We wire it up, test the bridge, and deploy the first hybrid build before touching the rest. Keeps users happy, keeps releases clean. It’s the safest way to move toward cross-platform without risk.
How do you keep apps secure?
We encrypt data in transit and at rest, we secure end-points and keep auth tokens off the client. For anything sensitive, we use native modules and Keychain or Keystore storage. React Native gives us the same control as native development, we just apply it properly. Every release goes through dependency audits and OWASP-style testing before it ships.
What slows projects down?
Where do we start, it could be anything from changing priorities mid-build. Missing assets. Bad documentation, unless feedback cycles. That’s why we plan hard up front, data models, routes, user stories. Once those are set, React Native’s fast. Two platforms move together, no duplication, no waiting for one side to catch up. Projects drag when scope drifts. We keep it tight, keep it moving.
How do you handle updates?
We fix what needs fixing and move onto the next ticket. React Native makes this easy, one code push hits both iOS and Android stores. We like to keep versions light, avoid piling features together. Smaller updates mean fewer bugs and faster approvals.
Do you offer post-launch support?
Where do we start, it could be anything from changing priorities mid-build. Missing assets. Bad documentation, unless feedback cycles. That’s why we plan hard up front, data models, routes, user stories. Once those are set, React Native’s fast. Two platforms move together, no duplication, no waiting for one side to catch up. Projects drag when scope drifts. We keep it tight, keep it moving.
We were going in circles until Ronins stepped in, they got us focused, showed us what mattered, and built a solution that didn’t rip out everything we’d already invested in.
