Web and mobile apps 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.
We work best with brands hiring an app development agency who want a partner that ships. Cross-platform app development with React Native, Next.js, and production backends.
What you get
- Web and mobile apps
- Shared design systems
- API and cloud setup
- Store and web launch
- One studio accountable for the result
- Design and engineering on the same schedule
- Support available after launch
How engagement works
As your app development 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 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 London 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 app development 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
- Next.js
- server rendering and static generation in one framework, so marketing pages stay fast and app routes stay dynamic
- NestJS
- structure and dependency injection on the backend, which keeps a growing API from turning into a pile of route handlers
- Firebase
- auth, push, and realtime sync without standing up your own infrastructure first
- AWS
- the services you grow into, once a managed platform stops being enough
What the first weeks look like
- Week 1
Scope and architecture
Users, data, integrations, and constraints, ending in a written plan for the 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. web and mobile 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 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 London
Same timezone and a face to meet, which genuinely matters for some teams. You are also paying London market for SaaS, fintech, and AI product talent. rates for the whole team including the layers that never touch your app development, and a local shortlist is a small shortlist.
Arcode
A small senior team. The people who scope the 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 London
London market for SaaS, fintech, and AI product talent. We work with clients in London remotely and keep overlapping hours in GMT/BST. We usually collaborate in English.
How we work with London teams
London is on GMT/BST, which gives us an overlapping working day rather than a handful of shared hours. Standups, reviews, and demos all fit in normal business hours for both sides.
What London clients usually need
London work is heavily SaaS and fintech: dashboards over real financial data, onboarding and KYC flows, and increasingly LLM features layered onto products that already have paying users.
Contracts, data, and compliance
Procurement in London tends to ask for a DPA, evidence of where data sits, and a security questionnaire before signing. We handle those upfront, and we keep personal data in UK or EU regions by default.
