Websites and
apps, built right.
We design and build the software your business runs on: marketing websites, web applications, and native or cross-platform iOS and Android apps, architected to stay stable as you grow, not just to launch.
No handoffs between a designer, a developer, and whoever fixes it later; the same team carries the project end to end.
Websites and web apps
Marketing sites, web applications, and the backend integrations they run on.
↗iOS and Android apps
Native or cross-platform, chosen to fit the product, not a default stack.
↗Deployment and handoff
Store submissions, hosting, and a clean handover once it's live.
↗What we
build.
Five parts of one build, from the first idea to a live product.

Websites and web apps
Marketing sites, portals, and web applications built on clean code and a sound architecture, so they stay fast and easy to extend as the business grows. That includes interactive parts such as booking flows and calculators, and sites that work in more than one language for audiences across the UK and EU.
- 01Marketing sites and portals
- 02Booking flows, dashboards, and calculators
- 03Multilingual sites

iOS and Android apps
Apps for iPhone and Android, built native or cross-platform depending on what the product needs rather than on a default stack. We choose native when performance or platform-specific features matter and shared code when it makes more sense, then take the app all the way to the stores.
- 01Native iOS and Android apps
- 02Cross-platform apps from shared code
- 03Store-ready builds

Backend, APIs and integrations
The part users never see but everything depends on: accounts and logins, databases, payments, and the third-party services your product talks to. We design the backend alongside the interface, so data, screens, and integrations fit together from the start.
- 01Accounts, logins, and data
- 02Payments and third-party services
- 03APIs your product can grow on

MVPs and prototypes
A working first version that lets you test an idea with real users before committing to the full build. We scope it tightly around what the product has to prove, so you learn what works before the larger investment.
- 01Scoping around the core idea
- 02Working prototype or first release
- 03A clear path to the full build

Launch and handover
Getting a product live is its own piece of work. We handle deployment and hosting, prepare the App Store and Google Play submissions, and hand everything over cleanly once it’s live, with the same team still available if anything needs attention afterwards.
- 01Deployment and hosting
- 02App Store and Google Play submission
- 03A clean handover once it’s live
From scope
to shipped.
"Good work needs room to think."Coadex, on how we take on projects
We keep the number of engagements deliberately small, so the same team that scopes a build is still the one shipping and supporting it months later.
- 01Scope and architectureWe map what the product actually needs to do before any design or code: screens, data, integrations, and platform choice.
- 02Design and buildInterfaces and the code underneath move together, reviewed against the real scope as we go, not bolted on at the end.
- 03Launch and submissionDeployment, store listings, and the practical steps that get a website or app actually live.
- 04Ongoing careSecurity patches, OS updates, and bug fixes so the product keeps working well after handoff.
One example,
in the open.
Most of our app and web development work sits under NDA. Here's one client we can show in full.
R.B.: Private Coaching
R.B. is a high-end personal swimming coach whose business ran on scattered messages and manual scheduling. We designed and built a website that puts everything his clients need in one place: session bookings, availability, event details, and service information, wrapped in a visual identity that matches the standard of his coaching.
- 01Website strategy and design
- 02Booking and scheduling experience
- 03Front-end development
Additional app and web development work is covered by client NDAs, a normal part of how we work, not a gap in the portfolio.
Before you
get in touch.
Both. We choose based on what the product actually needs, not a default stack: native when performance or platform-specific features matter, cross-platform when shared code makes more sense.
It depends on scope: a marketing site and a full mobile app are different timelines. We'll give you a realistic estimate before any work starts.
Yes. We regularly step into existing codebases for redevelopment, fixes, or ongoing maintenance; it doesn't have to start from zero.
Yes, as standard. It's why most of our app and web development clients aren't named publicly.
