Visual design that serves the interaction, not the portfolio
User interface design covering layout, visual hierarchy, and component design for web and app interfaces.
User interface design is the visual and interactive layer of a product - layout, typography, colour, and component design - applied to an existing structure so that what the user needs to do next is visually obvious.
What is User Interface Design?
We design the visual layer of your product or site - layout, typography, colour, and every component like buttons, forms, and navigation - built on top of a structure your users have already validated. It's the part people notice first, which is exactly why it needs to serve the interaction and not just look good in a portfolio.
A visually striking interface that obscures the primary action has failed at its actual job, however good it looks in a portfolio - hierarchy exists to answer one question fast: what does this screen want the user to do? Inconsistent component design compounds as a product grows, too - a button styled three different ways isn't a style problem, it's a sign the interface wasn't designed as a system.
It's different from UX structure and wireframing, which decides what a screen should do before this decides what it should look like, and from a full design system, which formalises this same visual layer into a documented, reusable library once a product has grown past one designer.
Common problems we solve
Novelty over recognition
Balancing visual distinctiveness against the plainer patterns users already recognise and trust.
Hierarchy drift
Keeping hierarchy consistent as a product adds screens over time.
Designed for one screen size
Designing for the real range of devices rather than the one screen in the design file.
Same button, styled three ways
Inconsistent component styling is a sign the interface wasn't designed as a system.
Everything covered in this service
Hierarchy
Primary action visually dominant, secondary actions clearly subordinate, decoration never competing with function.
Typography
A limited type scale applied consistently, with legibility prioritised over novelty.
Colour
A defined palette tied to function, with sufficient contrast and consistent meaning.
Component Design
Every component styled once and reused, with all states designed - default, hover, active, disabled, error.
Responsiveness
Layout logic defined per breakpoint, with touch targets sized for the input method.
Our optimization framework
Inherit the Structure
Start from the validated wireframes and flow, not a blank canvas - visual design applies to a structure that is already agreed.
Establish the System
Define type scale, colour palette, and spacing rules before designing individual screens, so decisions are consistent from the first screen.
Design Components First
Build the reusable pieces first, then assemble screens from them, rather than designing each screen from scratch.
Design All States
Every interactive element gets its hover, active, disabled, and error states designed - not left for development to improvise.
Review Across Breakpoints
Check every screen at mobile, tablet, and desktop widths before handoff, not after a developer flags a problem.
Hand Off With Spec
Deliver redlines and component specs precise enough that development doesn't have to guess at intent.
What actually changes
| Before | After |
|---|---|
| A button redesigned slightly differently on each screen | A button designed once and reused everywhere |
| A change requires hunting down every instance | A change propagates from one source |
| Hover and error states improvised during development | Every state designed before handoff |
| Reviewed at one screen width | Reviewed at mobile, tablet, and desktop widths |
What we report on
Action clarity
Whether the primary action on each screen is visually unambiguous.
Component consistency
Consistency of component styling tracked across the product.
Accessibility
Contrast ratios measured against accessibility guidelines.
Tools & platforms
Industries we optimize for
Built for teams like yours
Why choose EASI7
We fix tracking before we touch results
Every engagement starts with the same audit we'd run on our own accounts, so the numbers you're optimizing against are actually true.
One accountable team, not siloed vendors
The same team that does this also owns the rest of your stack - no handoff, no blame-shifting between vendors.
Built for how AI search actually works
Everything we build is structured to be extractable by AI answer engines, not just ranked in a list of blue links.
Reporting tied to your own dashboard
Every number we report ties back to GA4/GTM events you can see directly - not a screenshot from a tool you can't independently verify.
The most common visual design failure isn't bad taste - it's designing screens in isolation instead of components. A screen-by-screen approach can look fine reviewed one page at a time and still produce an interface where the same action is styled three different ways across the product.

How to engage us for this
Project-based
A defined outcome with a start and end date - an audit, a migration, a campaign build, a tracking overhaul. Fixed scope, fixed price, agreed upfront.
Ongoing retainer
Continuous management and optimization once the initial build is live - campaigns, SEO, reporting, and iteration run every month under one accountable team.
Advisory
Strategy and oversight without full delivery - we review what's already running, unblock decisions, and point an in-house or existing team in the right direction.
Common questions
After - visual design applied to an unvalidated structure usually means redoing screens once the structure changes. We sequence structure first, visuals second.
No - visual design following a validated structure and consistent hierarchy strongly improves the odds, but individual taste and context vary enough that we won't promise a specific test outcome we don't control.
Figma is our default for interface design and component specification, since it handles both design and developer handoff well. We can work in whatever tool a team already has established, if there is one.
Redlines, spacing and sizing specs, exportable assets, and component documentation - enough for a developer to build from without needing to guess at intent or ask us for every measurement.
Only if the confusion is visual rather than structural. If the underlying flow or information architecture is the actual problem, restyling it won't fix that - which is why we check the structure first.
Have validated wireframes ready for visual design?
We'll take the structure you've already agreed and build the interface on top of it, component by component.

User Interface Design, in detail
Scope, area by area
| Area | What we deliver |
|---|---|
| Screen designs | Full visual designs for each key screen and state |
| Component specifications | Every reusable element defined with its states |
| Responsive variants | Layout behaviour defined across mobile, tablet, and desktop |
| Developer handoff | Redlines, spacing, and asset export ready for build |
How this compares
| Component-Based UI Design | Screen-by-Screen Design |
|---|---|
| A button is designed once and reused everywhere | A button gets redesigned slightly differently on each screen |
| Changes propagate from one source | Changes require hunting down every instance |
| Scales cleanly as new screens are added | Inconsistency compounds as new screens are added |
Component-based design takes longer to set up initially in exchange for consistency later.
What we measure this against
- Whether the primary action on each screen is visually unambiguous
- Consistency of component styling across the product
- Contrast ratios against accessibility guidelines
Where this applies
- A product moving from validated wireframes into full visual design
- A design system audit where components have drifted inconsistent across a growing product
- A rebrand that needs to apply a new visual identity to an existing interface structure
