Features

What we deliver

High-Fidelity UI

Pixel-perfect screens with real typography, colors, components, and brand feel—ready for stakeholder review.

Interactive Flows

End-to-end journeys with clickable navigation, transitions, and interactive components that simulate real behavior.

Responsive Variants

Mobile-first + desktop/tablet variants so you can validate layout and interactions across devices.

Testing-Ready Prototypes

Built to run usability tests smoothly—task flows, realistic screens, and measurable completion paths.

Reusable Components

A mini design system (buttons, inputs, cards, modals) so future screens are faster and consistent.

Dev Handoff Pack

Annotated specs, component states, spacing rules, and exported assets so engineers build accurately.

Use Cases

Who this is for

MVP Validation

Test the core flows with users before coding. Catch confusion early and reduce build waste.

Feature Testing

Prototype a feature, test it, iterate quickly, then ship with confidence (and stakeholder buy-in).

Design Systems

Build reusable components with interaction demos—perfect for teams that want consistent UI at speed.

Client / Investor Demos

Clickable prototypes that sell the vision better than static screens—great for pitches and approvals.

FAQ

Frequently asked questions

Wireframes focus on structure and layout. High-fidelity prototypes look and feel like the final product, including UI details and interactions—so testing is more realistic.

Yes. Prototypes are ideal for user testing because iteration is fast and cheap. We run tests using Maze/UserTesting or your own participant pool.

Yes—where they improve clarity and delight. We use Figma for standard transitions and Framer/Principle/ProtoPie for advanced motion and interactions.

Yes. We deliver a handoff pack with screen specs, component states, design tokens, assets, and implementation notes to reduce back-and-forth.

Delivery considerations for your region

Compliance & Data (UK/EU)

For UK teams, we default to GDPR-first thinking: data minimisation, purpose-limited storage, and clear access boundaries.

We can work under a DPA (template available on request) and implement practical retention/deletion flows when needed.

  • GDPR-first patterns (minimise, restrict, document)
  • DPA template available on request
  • Retention/deletion and export flows where required
  • Least-privilege access and secure session handling
  • PII-safe logging + secure-by-default configuration
  • NDA available for early-stage discussions

Timezone & Collaboration (UK/EU)

We align to UK time and EU overlap (GMT/BST with CET-friendly windows) for fast feedback cycles.

We keep the process lightweight: async updates, clear priorities, and written decisions to avoid ambiguity.

  • UK/EU overlap with GMT/BST windows
  • Async-first delivery with documented scope
  • Weekly milestones and structured demos
  • Clear escalation path for blockers
  • Tight change control with clear sign-offs

Engagement & Procurement (UK)

We support typical UK procurement flows with clear scopes, change control, and invoice cadence.

If you prefer a discovery-first engagement, we can run a short paid discovery to lock requirements before build.

  • GBP-based engagements and invoicing options
  • Discovery-first option to reduce delivery risk
  • Milestone-based billing when appropriate
  • Transparent change control and sign-offs
  • Vendor onboarding pack on request

Security & Quality (UK/EU)

We build for reliability and maintainability: clean PRs, tight review loops, and test coverage that matches risk.

Performance budgets and release checklists keep launches predictable—especially when multiple stakeholders review changes.

  • CI-friendly testing: unit + integration + smoke tests
  • Performance budgets + bundle checks (Core Web Vitals-minded)
  • Structured release notes and rollback-safe deployments
  • Security checklist for auth, roles, and data flows
  • Observability hooks (logs + error tracking) ready for production
