Web and mobile app
development that
holds up on real devices.
Production web and mobile applications, accessible, performant and maintainable, built end to end on the Agentic SDLC.
Trusted on systems that cannot fail
What you get from our web and mobile work.
Six properties every build carries, decided at design time rather than retrofitted before launch.
Responsive design
Mobile is most of the traffic, so responsiveness is decided at every step. Desktop and mobile hold their functionality, not just their layout.
Usability
Interfaces that are easy to navigate at any level of technical proficiency, designed to remove friction rather than decorate it.
Security and reliability
Security testing before release, secrets held server-side, hosting and CI/CD chosen so deployments carry no downtime.
Customisation
Features, functions and interfaces you can personalise and modify, so the product adapts inside the budget you have.
Easy maintenance
A centralised architecture that keeps updates and fixes low-cost, deployable to every user or a selected group.
Flexibility and scalability
Built to scale or extend with new functionality, so the system does not become the thing you outgrow.
Web and mobile app development,
from discovery to release.
One team, accountable for the whole lifecycle, not a slice of it.
Product and UX discovery
Flows, scope and a behavior-first spec agreed before the first screen is built.
Responsive web apps
Fast, accessible web applications engineered to hold up under real-world load.
Native and cross-platform mobile
iOS, Android and cross-platform apps built and shipped from one governed codebase.
Design-system engineering
Reusable, tokenized components so the UI stays consistent as the product grows.
Accessibility and performance
WCAG-aligned, performance-budgeted builds, measured rather than assumed.
Continuous testing and release
Spec-derived tests and CI/CD so every release ships with evidence behind it.
What we build it with.
Web, iOS and Android, layer by layer. Chosen for what your team can operate and hire for, not for what is new.

Spec-driven, AI-assisted
delivery, governed end to end.
AI agents build. Senior engineers hold the gates. The framework that turns AI speed into governed, predictable delivery, from the first call through to support after launch.
- 01
Assess
We map the system, risks and constraints. Honest, fast, no obligation.
- 02
Spec
Requirements become behavior-first specifications before any code. Accessibility acceptance criteria and performance budgets are written into the spec, not bolted on before launch.
- 03
Build
AI agents build from the specs; senior engineers hold every gate. Progress is measured as coverage against the spec set, not as tickets closed.
- 04
Govern
Tests, hooks and reviews enforce the standard continuously in CI. Accessibility and performance are gates, not a report someone writes at the end.
- 05
Ship and scale
Release, observe and harden. We handle store submissions and review responses; the developer accounts stay in your name.
One product team
across web and mobile
Digi Group needed web and mobile to move together rather than in separate release trains.
One product team across web and mobile, on a single release cadence.
Digi Group needed web and mobile to move together rather than in separate release trains. We consolidated delivery around one spec set and one component library, with critical journeys covered end to end in CI on every change.
- Release cadence across platforms

- Every milestone delivered
- Day one
"High quality, on-time delivery. The team is proactive and supportive."
How we work together
Three shapes. After the assessment we tell you which one fits, including when the answer is none of them.
Product build
You need the app designed and built.
Embedded product pod
Continuous delivery on a live product.
Quality sprint
The app exists but fails the quality bar.
Every engagement starts with an assessment. It is fixed price, it ends in a written plan, and the plan is yours whether or not you continue with us.

All servicesFrequently asked questions.
Something not covered here? Ask an engineer directly, no SDRs, no funnel.
Native or cross-platform?
It depends on what the app does. Heavy device integration or sustained performance work argues for native. Most product apps ship faster and stay cheaper on React Native or Flutter. You get the trade-off in writing before the decision is made.
What accessibility standard do you build to?
WCAG 2.2 AA by default, with acceptance criteria written into the spec and automated checks in CI. We can align to EN 301 549 or Section 508 where procurement requires it.
Do you work with our designers?
Yes. We can build to your design system or engineer one with you. Either way it ships tokenized and documented.
Can you take over an existing app?
Often. We start with an audit and a characterization test pass, so we know what we are changing before we change it.
Who handles store submissions?
We do, including review responses. The developer accounts stay in your name.
