:: Services / UI/UX design
UI/UX design services for products people understand on first use
Good design is mostly about removing doubt: where to tap, what happens next, why a number looks wrong. We research how your users work, test ideas as clickable prototypes, and hand over designs your developers can build without guessing.
Research before pixels
Clickable prototypes
Developer-ready handoff
:: What we do
What our UI/UX design covers
Pick one piece or take the whole path from research to a shipped design system.
01
User research
Interviews, analytics review and task walkthroughs with real users, so design decisions rest on evidence, not opinion.
02
UX audits and redesigns
A screen-by-screen review of an existing product with a ranked list of fixes, then a redesign of the flows that cost you most.
03
Wireframes and user flows
The structure of every screen and the paths between them, agreed before anyone spends time on visual polish.
04
Interactive prototypes
Figma prototypes you can click through and put in front of users or investors before code is written.
05
Visual UI design
Interfaces for web, iOS and Android that follow your brand, meet accessibility guidelines and work on every screen size.
06
Design systems
Reusable components, tokens and documentation so new screens stay consistent as your product and team grow.
:: UX audit
What a UX audit looks at
A UX audit finds where people get stuck, using your analytics, recordings and a structured review. You get a ranked list of fixes, not a redesign you did not need.
What we review
Key journeys such as sign-up, checkout or booking
Where users drop off in analytics and recordings
Navigation, labels and information structure
Forms, errors and empty states
Accessibility basics: contrast, focus, text size
Speed and layout on phones
Common problems we find
Too many steps before the first value
Buttons and labels that mean different things
Forms that lose data on an error
Important actions hidden in menus
Mobile layouts squeezed from desktop
:: How it works
How a design engagement runs
Short loops of design, test and adjust, with your team involved at each step.
Week 1
Understand
Stakeholder workshop, user interviews and a review of your analytics and support tickets.
Weeks 2 to 3
Structure
User flows and wireframes for the key journeys, reviewed with you every few days.
Weeks 3 to 5
Design and test
High-fidelity screens and a clickable prototype, tested with five to eight real users.
Handoff
Build-ready
Annotated Figma files, a component library and design QA while developers build it.
:: Design systems
What goes into a design system
A design system keeps a product consistent as it grows and makes every new screen faster to design and build. These are the parts we deliver.
Foundations
Design tokens
Colours, type scale, spacing, radius and shadows, named once and used everywhere, including dark mode.
Building blocks
Components
Buttons, inputs, tables, cards, modals and navigation, with every state such as hover, error and disabled.
Patterns
Page patterns
Ready layouts for common screens such as lists, detail pages, settings and onboarding.
Figma
A shared Figma library
Components with variants and auto layout, so designers build new screens in hours, not days.
Code
A matching code library
React or Flutter components that match the Figma library, so design and build stay in step.
Docs
Usage guidelines
When to use each component, content rules and accessibility notes, written for designers and developers.
:: Cost and timeline
How much does UI/UX design cost?
Typical prices for our design work, based on senior designers at $25 to $35 an hour.
UX audit
$3k – $8k
2 to 3 weeks
Analytics review, heuristic review and a ranked list of fixes for your main journeys, with quick sketches of the top fixes.
Product redesign
$8k – $30k
4 to 10 weeks
Research, user flows, wireframes, visual design and a clickable prototype for a web or mobile product.
New product and design system
$30k – $70k
2 to 4 months
Research through to a full design system in Figma, ready for developers, with design support during the build.
Design and build together
Because our designers work next to our developers, designs are checked for build cost as they are made. That avoids paying for screens that are expensive to build and rarely used.
What moves the price
Number of journeys and screens
User research and testing rounds
Web, mobile or both
Design system depth
Accessibility requirements
:: Why Sterling
What you get
Figma files you own, organised and named for developers
A tested prototype, not just static screens
Accessibility checked against WCAG 2.2 AA
A component library that matches the code
Designers who stay through development for design QA
