Product UI that feels obvious to use

User flows, dashboards, onboarding and design systems for SaaS and healthcare apps, designed so new users get value fast and your engineers can build without guessing.

What you get

What’s included

Every project is scoped to your goals, but these are the pieces you can count on.

Good product UI disappears

When product design works, users do not notice it. They sign up, understand what to do, get value, and come back. When it does not, every confusing screen becomes a support ticket, a churned trial or a sales call spent explaining the interface.

We design product interfaces around the tasks users came to do, not around the features the team is proudest of.

How we work on product UI

Understand the jobs. We start with the tasks that matter most: what users are trying to achieve, what they know already and where they currently get stuck. Analytics, support tickets and short interviews tell us where to focus.

Map the flows. Each key task is mapped end to end, including empty states, errors, permissions and edge cases. Most usability problems live in the states nobody designed.

Prototype and test. Clickable prototypes go in front of real users before engineering commits time. Five sessions usually reveal the big issues.

Design in a system. High-fidelity screens are built from a shared component library with tokens, states and usage notes. It mirrors how your front end is built, so design and code do not drift apart.

Hand over and support. Engineers get organised Figma files, specs and a walkthrough, and we stay available during the build to answer questions and review implementation.

Onboarding and activation

The first session decides whether a trial converts. We design onboarding flows, setup checklists and empty states that move new users to their first meaningful result as fast as possible, and we connect that work to how your marketing site sets expectations before signup.

Health tech

Healthcare interfaces carry extra weight: patients may be anxious, clinicians are short on time, and the data is sensitive. We design calm, accessible interfaces with clear language, generous touch targets and careful consent and privacy flows, working with your compliance team on the requirements that apply to you.

A consistent brand, inside and out

Product UI and brand should feel like one company. If your identity needs work before the product does, see branding and identity.

FAQ

SaaS & healthcare app UI
questions

Anything else? Email us at rajan@thevectorbox.com.

Do you design mobile apps as well as web apps?

Yes. We design responsive web apps and native iOS and Android interfaces, following each platform's conventions where they matter and sharing one design system across them.

Can you work with our existing design system?

Yes. We can extend and tidy an existing system, or build one from scratch if your product has grown without one. Either way, components are aligned with how your engineers build them.

Do you have experience with healthcare products?

Yes. We have designed interfaces for health-tech products where accessibility, clarity and trust matter more than usual. We design consent, privacy and data-sharing flows carefully, and work with your compliance team on requirements such as HIPAA.

Do you test designs with users?

Where possible, yes. We prototype key flows and test them with a handful of real or representative users before handing over, which catches most usability problems cheaply.

Do you build the product as well?

Our focus is design and front-end handover. We work closely with your engineering team, and can build marketing sites and lightweight MVP front ends on low-code tools when that is the faster route.
