Product design services for web and mobile apps

UX research, user flows, interfaces and design systems, tested with real users before anything is built.

Design services we offer

Seven services, from the first interview to the system your developers build from. Take one, or all seven.

  • UX research

    Interviews, analytics and a look at your competitors, so the design starts from what users do rather than what anyone assumes.

  • UX design

    User flows, wireframes and clickable prototypes that settle how the product works before it is drawn in detail.

  • UI design

    Every screen in every state — empty, loading, error and full — in a visual language that is yours.

  • Design systems

    Components and tokens in Figma, kept in step with the ones in code, so new screens are assembled rather than redrawn.

  • Usability testing

    People like your users try the prototype; where they get stuck, the flow changes before anyone builds it.

  • Accessibility

    Contrast, text size, focus order, labels and keyboard use, checked against WCAG as each screen is designed.

  • UX audit and redesign

    A review of your live product's flows, screens and drop-offs, then a redesign of what fails, shipped in steps your team can release.

Our product design process

Five steps, from what your users actually do to a design your developers can build.

  1. 01Scope

    Users, goals, analytics and competitors studied, with a UX audit if you're already live.

  2. 02Wireframes

    User flows, information architecture and wireframes for every key screen.

  3. 03UI design

    Every screen and state designed, with the design system built alongside.

  4. 04Prototype and test

    A clickable prototype tried with real users, fixed and tried again.

  5. 05Handoff

    Specs, tokens and the Figma library, with your developers' questions answered during the build.

Designed to be built

Whether we build it or your developers do, the design reaches the code with nothing lost: the same components, the same names, every state.

  • The same names

    Components, variants and tokens are named in the file the way the code names them, so nothing is translated on the way.

  • Every state drawn

    Empty, loading, error and disabled, drawn before anyone asks, so no state is left for a developer to guess.

  • Built by us, or by your team

    The same team builds it, or your developers get the files and the system to build it themselves.

We also build software for insurance (insurtech), government (govtech), energy and media. If your industry is not listed, we can still build for it.

Why SafeBlockLab

One studio that researches, designs and tests your product — and can build it too.

  • Designed by the people who build it.

    The designers and the engineers are one team, so no screen is drawn that the code cannot hold.

  • Tested with users before it is built.

    People like your users try the flows while changing them still costs a drawing, not a rebuild.

  • One system, in the file and in the code.

    Components and tokens carry the same names in Figma and in the codebase, so the product stays consistent as it grows.

  • Accessible from the first screen.

    Contrast, focus and labels are checked as each screen is designed, not patched after launch.

  • Design only, if that suits you.

    Hand the work to your own developers with every state drawn, or have the same team build it.

  • A written estimate first.

    Scope, price and dates in writing after a first call, before any design starts.

Questions about product design

The ones teams ask before they start one, answered plainly.

Ask your own
How much does product design cost?

It depends on the scope — a few key flows, a whole app, or a design system. After a first call you get a written estimate with the scope, the price and the dates, before any design starts.

How long does product design take?

It depends on the scope: a few flows take less time than a whole product and its design system. The estimate names the dates, and you see the work at every stage rather than at the end.

Can you design only, for our own developers?

Yes. We design and build together, or design on our own and hand the work to your developers — whichever suits your team.

Can you work with our existing designs or design system?

Yes. We can extend your design system, redesign what isn't working, or build from the Figma files your designers own.

What do we get at the end?

The design files, a clickable prototype of the key flows, and the design system the screens are built from. What is included is set out in the estimate.

How do you test designs with users?

We put a clickable prototype in front of people like your users and watch them try the key tasks. Where they get stuck, the flow is redesigned and tested again before anything is built.

Can you redesign a product that is already live?

Yes. A UX audit reviews the live product — its flows, its screens and where users drop off — and the redesign fixes what the audit finds, in steps your team can ship.

Do you design for accessibility?

Yes. Contrast, text size, focus order, labels and keyboard use are checked against WCAG as the screens are designed, not after they are built.

Do you build the design system in code as well?

Yes, when we build the product: the same components and tokens exist in the design file and in the codebase, under the same names.

Do you design websites as well as apps?

Yes. Web apps, mobile apps and websites, with the same process — from research to the screens and the system behind them.
