Cross-platform mobile from one studio
Plenty of agencies are built around long retainers. What you actually want is a live site, an app in the stores, and users adopting it.
Design and engineering share one backlog, so the visuals never drift away from what can realistically ship on time.
Most people who reach this page are brands searching for a React Native agency. React Native and Expo app development with production backends, payments, and store-ready delivery.
What you get
- iOS and Android apps
- Expo and native modules
- API and auth systems
- Store launch support
- One studio accountable for the result
- Design and engineering on the same schedule
- Support available after launch
How engagement works
As your React Native agency, we run a shared backlog, design reviews, and engineering sprints, and you keep one point of contact throughout.
- 01
Discover
Goals, constraints, data sources, and success metrics, all settled before we touch architecture or prompts. Nothing here waits on a handover between separate teams.
- 02
Design
System design, AI/tool boundaries, interface direction, and interaction prototypes. On React Native app development projects we favour practical architecture over trendy defaults.
- 03
Build
Modern stack, clean architecture, evaluated AI behavior, and iterative demos you can react to. The work for teams in the UK stays tied to the outcome you asked for.
- 04
Launch
Ship, monitor, harden, and keep improving models, tools, and product after go-live. You see progress on the critical path every week.
How we build it, and why
The stack is chosen per project, not applied from a template. For React Native agency work these are the defaults, and the reason each one is on the list.
- React Native
- one codebase for iOS and Android, which halves the surface area you maintain after launch
- Expo
- over-the-air updates and managed builds, so shipping a fix does not mean waiting on app store review
- TypeScript
- types across the whole stack, which catches the class of bug that only shows up in production
- Firebase
- auth, push, and realtime sync without standing up your own infrastructure first
- NestJS
- structure and dependency injection on the backend, which keeps a growing API from turning into a pile of route handlers
What the first weeks look like
- Week 1
Scope and architecture
Users, data, integrations, and constraints, ending in a written plan for the React Native app development that you approve before anyone opens an editor.
- Weeks 2-3
Design the critical path
The screens that carry the product, prototyped and clickable. Design and engineering review together, so nothing gets drawn that cannot ship.
- Weeks 4-8
Build in weekly slices
Every week ends with something on a real URL. ios and android apps lands early, because the rest of the plan depends on it working.
- Launch
Ship, measure, hand over
Release, monitoring, analytics, and a documented handover, so your team can carry it without calling us.
Weighing up your options
There are three realistic ways to get this built. Each is the right answer for someone.
A solo freelancer
Cheapest per hour and fine for a contained task. The risk on React Native app development is breadth — one person covering design, backend, infrastructure, and launch usually means one of them is weak, and there is no cover when they are unavailable.
A local agency in UK
Same timezone and a face to meet, which genuinely matters for some teams. You are also paying UK demand for product engineers and AI-capable studios. rates for the whole team including the layers that never touch your React Native app development, and a local shortlist is a small shortlist.
Arcode
A small senior team. The people who scope the React Native app development write the code, you get weekly demos instead of status decks, and the engagement ends when the thing is live and handed over.

Working with teams in UK
UK demand for product engineers and AI-capable studios. Work is remote-first (GMT/BST), with written updates you can read in your own time. We usually collaborate in English.
How we work with UK teams
UK teams get a full working-day overlap: our morning covers your morning, so questions raised at 9am are answered before your standup ends. Most UK clients settle into a Tuesday demo and a Thursday written update.
What UK clients usually need
UK briefs skew towards SaaS platforms, fintech-adjacent products, and replacing ageing internal tools. Several arrive after an agency retainer stopped producing releases.
Contracts, data, and compliance
We invoice in GBP or USD. UK GDPR and data residency come up on almost every project, so we default to EU or UK-hosted data stores and document where personal data flows before the build starts.
