Creative software and interface studio, London
Interfaces with depth
you can feel.
Sevenfold Studios designs and builds apps, websites and interfaces where every surface is considered: how it layers, moves, responds, and holds up long after launch.
We are a small London studio for organisations that care how software feels as much as what it does. Design and engineering sit together from the first week, prototypes are judged in motion on real devices, and nothing ships until it is accessible, fast and documented.
What the studio makes
- Interface designVisual systems, interaction and motion for products that need presence. Delivered as a living design system, not a folder of static pictures.
- Mobile appsiOS and Android apps with refined touch, transitions and haptics, built to respect each platform's conventions and older devices.
- Web developmentExpressive websites and web applications that stay fast on ordinary phones and remain editable by your own team.
- PublishingStore listings, screenshots and privacy answers crafted as carefully as the product, with review handled alongside you.
- CareUpdates, monitoring and refinement that keep the finish intact through every OS release.
Anatomy of a surface
A polished screen is the top sheet of several others. Choose a layer to see what we do there and what you receive. Most studios stop at the top two.
Layer 1 of seven
Structure
What exists and where it lives. Information architecture, navigation and the names of things.
You receive: Sitemap or screen map, naming list, content model
Layer 2 of seven
Content
The words, images and data people actually came for. Written for the reader, not the org chart.
You receive: Content plan, microcopy, image direction
Layer 3 of seven
Interaction
What happens when someone touches, clicks, types or waits. Every state, including empty and error.
You receive: Clickable prototype, state inventory
Layer 4 of seven
Motion
Movement that explains: where something came from, where it went, what changed. Never motion for show.
You receive: Motion principles, timing and easing tokens
Layer 5 of seven
Accessibility
Contrast, focus, screen readers, text size, reduced motion. Designed in from the first sketch.
You receive: WCAG 2.2 AA review, assistive technology test notes
Layer 6 of seven
Performance
How fast it feels on an ordinary phone on an ordinary connection. Depth must not cost speed.
You receive: Performance budget, measured before launch
Layer 7 of seven
Care
How the surface survives new OS versions, new content and new people editing it.
You receive: Design system documentation, care plan
Prototypes you can hold.
Static mock-ups hide the hardest questions: how a sheet slides, how a list behaves with real data, what happens on a small phone with large text. So we prototype in motion, on devices, early. It is cheaper to discover a problem in week three than in week thirteen.
Every prototype comes with notes on what we learned and what we would change.
The depth mixer
Depth in an interface is made from a handful of material properties. Adjust them and watch a surface change character. The values below are real CSS you could use, and the same thinking shapes the design tokens we hand over.
From first conversation to launch
Durations are typical ranges, not promises; we confirm them in writing for your project. Scroll sideways.
- Free
Conversation
A call about what you are making, who it is for and what good would feel like. We say early if we are not the right studio.
- One to three weeks
Shaping
Research, a written brief and a first direction in motion. You receive a fixed quote for the build before committing to it.
- Two to four weeks
Prototype
A working prototype on real devices, tested with people who resemble your users. The riskiest interactions are proved first.
- Agreed per project
Build
Design and engineering side by side, with a fortnightly build you can hold. Decisions are logged so nothing is lost.
- One to two weeks
Launch
Store submission or web release, performance and accessibility checks, and a quiet watch over the first days.
- Ongoing, optional
Care
Polish, Atelier or Bespoke care keeps the finish intact through updates.
Notes from the studio
A few principles we return to on every project. The full reading list is in Notes.
Motion should answer a question the user already has: where did that go?
If a screen only looks right with perfect sample data, it is not finished.
Reduced motion is a design state, not an afterthought. We design it alongside the full version.
Before you write to us
What sort of budget do you need?
It depends on scope. After a first conversation we propose a paid shaping phase with a fixed fee, which ends with a fixed quote for the build. You are never committed beyond the phase you have agreed.
Can you work with our in-house developers?
Yes. We often design and prototype while your team builds, or pair with them on the trickiest interactions. We hand over tokens and documentation they can use directly.
Do you take on small projects?
Sometimes: a focused interface refresh, an accessibility and motion review, or a prototype to test an idea. Ask and we will be honest about fit.
When can we reach you?
Studio hours are Monday to Friday, 09:00 to 18:00 UK time. We meet in person by arrangement and work with clients across the UK.
No borrowed glory.
We do not list awards or clients on this site, and we will not invent them. We will show you our thinking, process documents and the standards we hold, in conversation.
