Software & apps

UI/UX design people understand at first glance.

Good software feels obvious. We design the screens, flows and details of web apps, mobile apps and portals — from first sketches to clickable prototypes you can test with real users — and hand over a design system that keeps everything consistent as it grows. Problems are found while they are cheap to fix: on screen, before any code is written.
What you get
  • User flowsThe paths people take
  • PrototypesClickable before it’s built
  • Design systemColors, type, components
  • AccessibilityReadable and usable for all
The short answer

What is the difference between UI and UX design?

UX (user experience) design decides how a product works: what people need to do, the steps they take and what happens at each one. UI (user interface) design decides how it looks and feels: layout, type, color, buttons and the small details on each screen.

The two only work together. A beautiful screen in the wrong flow still confuses people; a sensible flow with a cluttered interface still feels hard. We do both in one process, starting with how people work and finishing with screens your developers can build exactly.

Deliverables

What do you hand over at the end?

Research notesWho the users are, what they need and where today’s tools fail them.
User flowsEach key task mapped step by step, including errors and edge cases.
WireframesSimple layouts that settle structure before visual detail.
Clickable prototypeRealistic screens you can click through on desktop and phone.
Design systemColors, type, spacing and reusable components, documented.
Developer specsSizes, states and behavior so the build matches the design.

Why design first

What happens if we skip design and go straight to building?

Building without design
  • Flows decided by whoever writes the code
  • Problems found by users after launch
  • Every screen looks slightly different
  • Changes cost development time
Designing first
  • Flows agreed and tested before code
  • Problems found in a prototype, cheaply
  • One consistent design system
  • Developers build from clear specs
Accessibility

How do you make designs accessible?

We design to the WCAG guidelines from the first screen, not as a fix at the end. That means readable contrast and text sizes, controls large enough to tap, clear labels and error messages, and layouts that still work when text is enlarged or a keyboard or screen reader is used. Building it in from the start is far cheaper than an accessibility audit after launch.

FAQ

Questions we get asked

Can you design for a product someone else builds?
Yes — we hand over prototypes and a design system your developers can work from.
Do you test designs with users?
Yes. We test prototypes with a few real users before anything is built.
Can you redesign an app we already have?
Yes. We start by watching how people use the current version and where they struggle, then redesign the parts that matter most, so the improvement can ship in stages.
How many users do you need for testing?
A handful of people who match your real users usually reveal the biggest problems. We test, fix and test again, rather than running one large study.
Do you design websites too?
Yes. Marketing websites and online stores are part of our websites and e-commerce service; this page covers apps, portals and other software products.
Do you follow our existing brand?
Yes. If you have brand guidelines, we build the design system on them. If you don’t, we create a simple set of colors, type and components that suit your brand and can be reused across products.
Will the design work on phones?
Yes. We design for phone and desktop together and check the prototype on real devices, because many users will only ever see the small screen.
How long does the design stage take?
It depends on the number of screens and flows. We agree the stages up front — research, flows, prototype, design system — and you see and approve each one before the next starts.
What do our developers receive?
The clickable prototype, the design system with every component and its states, and specs for spacing, sizes and behavior — enough to build without guessing.
