UX and UI design

Interfaces for people who are busy, outdoors, or being audited

We design the screens that go with the systems we build: field apps used one-handed in poor light, operator dashboards, and product interfaces a brand is judged on. Prototypes get tested before anyone writes production code.

Design here is not a separate phase you buy. It is how the build avoids being wrong.

What we test a prototype against, before build.

What kind of design

We are not a branding studio

Two different trades share the word design. Knowing which one you need saves months.

Go to a brand studio for

Identity and campaigns

  • Logo, brand system, tone of voice
  • Marketing sites and campaign pages
  • Photography and illustration direction
  • Packaging and print

We will work to a brand system you already have, but we do not create one.

Come to us for

Interfaces that carry work

  • Field apps used in bad conditions by trained staff
  • Operator dashboards where mistakes cost money
  • Product interfaces that must feel worth paying for
  • Forms and workflows that follow a regulated procedure
  • Migration screens where old habits meet a new system

We design what we then build, so the handover between design and engineering does not lose anything.

Plain definitions

Two questions worth settling before you brief anyone

Both get asked on almost every first call, and the answers change what you should be buying.

What is the difference between UX and UI?

User experience is the decision about what the screens are and in what order somebody moves through them. It comes out of watching the job being done. User interface is what those screens look like and how they behave under a finger or a cursor.

You can have a beautiful interface over an experience that makes people give up, and it happens often. The reverse is rarer and less damaging. Both matter, and on the work we do the experience half is where the money is saved.

What is a design system, and do you need one?

A design system is a set of components with the rules for using them, held in one place and shared by design and engineering. Buttons, forms, tables, spacing, states.

You need one when more than one team touches the product, or when the product will outlive the people who started it. For a single app built once it is overhead. We hand over a component library in code either way, because that is what stops the build drifting from the design.

What you get

Six things we produce, all of them usable

Task map
What each role actually does, in order, including the workarounds they have invented. Usually the most useful document of the project.
Clickable prototype
Tested with real users before production code. For Verify Auto we validated the design with stakeholders through prototypes first.
Screen designs at real density
Designed with your actual data volumes, not with three tidy rows in a table.
Component library
Handed over as code alongside the design file, so your team can extend it without guessing.
States nobody remembers to design
Empty, loading, offline, error, partial permission and too much data. These decide whether an app feels solid.
Accessibility baseline
Contrast, target size, keyboard order and labelling. On field apps this is practical, not decorative.

What people ask us for

Six kinds of design work we take on

Every one of these is an interface that carries work, which is the only kind we do.

Field application design
One hand, gloves, bad light and interruptions. Target size and contrast stop being aesthetic questions here.
Operator and supervisor dashboards
Where somebody watches a lot of things at once and a missed signal costs money. Density and hierarchy matter more than polish.
Product interface for a paid tier
Where the interface is part of what is being sold. Verify Auto needed the finish to match the brand as precisely as the logic matched the standard.
Regulated forms and workflows
A procedure that has to be followed in order and evidenced afterwards, designed so the compliant path is also the fastest one.
Migration screens
The most neglected work in any replacement project. People arrive with years of habit from the old system and meet a new one on a Monday morning.
Design system and component library
Components in code alongside the design file, so your engineers extend it rather than guess at it.

Tell us who uses it and where

Three fields. A designer reads it, not a sales rep. You get an answer within one working day.

  • We map the tasks and the conditions they happen in
  • You get a plan for prototype and testing, with a cost band
  • No obligation, and no phone number needed to start

Our work

When the interface was the blocker

Case study, automotive

A premium interface for a brand that is judged on finish

Verify Auto needed a safety compliance app whose interface matched the brand as precisely as the logic matched the standard. We designed to exacting standards, validated the direction with their stakeholders through prototypes before production code, and kept the build modular so the look could scale across the range.

  • Prototype-led
  • Stakeholder validation
  • Xamarin
  • Angular

Case study, United Kingdom

An interface that was holding back sales

Hydrajaws had testing software their customers found hard to use, and it showed in the commercial results. The rebuild gave the apps a clearer structure, a free tier that let people try it, and a premium tier that reads instruments directly.

  • .NET
  • Angular

How the work runs

Watch the work before drawing anything

  1. Week 1

    Watch and map

    We sit with the people doing the job, in the place they do it. Workarounds get written down, because they are the requirements nobody says out loud.

  2. Week 2

    Prototype

    Clickable, at real data density, covering the awkward states as well as the happy path.

  3. Week 3

    Test and revise

    Put it in front of real users, unaided. Fix what fails, then get sign-off from whoever owns the process.

  4. Into build

    Hand over as code

    Component library and specs go to engineering, who are usually us, so nothing is lost in translation.

Tools and deliverables

What you receive, and what it is made in

The file is not the deliverable. The component library your engineers can build against is.

Design and prototyping
Figma, or whatever your team already uses. The prototype is clickable and tested, not a slide deck of screens.
Component library in code
Angular or React components handed over with the design file, so the built product does not drift from what was approved.
Task map
What each role does, in order, including the workarounds they invented. This is usually the document clients keep referring back to.
State coverage
Empty, loading, offline, error, partial permission and too much data, designed rather than discovered during build.
Accessibility baseline
Contrast, target size, keyboard order and labelling checked against WCAG 2.2 AA. A formal accessibility audit is a separate exercise and we will say when you need one.
Testing
Moderated sessions with real users, five to eight per role, run unaided so we find what stops people rather than what they say about it.

Who does the work

Twenty engineers, eight of them senior

Designers here sit with the engineers who build the thing. That is the whole argument for buying design from a team that also ships code.

You meet the designer before you commit. Ask to see a task map from a previous project, because that document shows how a team thinks better than a portfolio does.

How we work

Five engagement models, and you pick how much you keep

The models differ in one thing: how much of the management you hand over. Everything else, including who owns the code, is the same in all five.

Changing model later is normal. Augmentation into a dedicated team is the common direction, and the people stay.

Engineers join your team and work inside your process, your board and your code review.

FAQs

Questions we get on the first call

Can we buy design without the build?

Yes. You get the task map, the prototype, the screens and a component library, and you can take them to any engineering team. We would rather that than design something nobody builds.

Do you work to our existing brand?

Yes, and we prefer it. We apply a brand system, we do not create one.

How many users do you test with?

Enough to find the blocking problems, usually five to eight per role. The aim is to find what stops people, not to produce statistics.

What if our users are hard to access?

Then we test with the closest proxy we can get and say clearly what that limits. Designing without any contact with users is guesswork, and we will tell you that rather than proceed quietly.

Figma or something else?

Whatever your team can pick up. The deliverable that matters is the component library in code.

Who owns the design files?

You do, along with everything else we produce.

What does a design engagement cost, and how long?

A prototype and testing round for one application is typically three to four weeks. Where design leads into a build with us it sits inside the project rather than being priced separately, and the engagement model above decides how that is billed. Design bought on its own is quoted by the scope of the task map and the number of roles being tested, which we agree before starting.

Do you design to accessibility standards?

We work to WCAG 2.2 AA as a baseline for contrast, target size, keyboard order and labelling, and on field apps that is practical rather than decorative. A formal accessibility audit against a legal obligation is a separate piece of work by a specialist, and we will tell you when your situation calls for one.

What if we already have a design system?

Then we work inside it, and we prefer that. We apply a brand system rather than create one. Where your system has gaps, which is usually in the states nobody remembers to design, we extend it in your own conventions and hand the additions back as components.

Show us where people give up

The screen everyone avoids, the form finished on paper instead. That is where the design work starts, and thirty minutes is usually enough to find it.
