DESIGN SYSTEMS FOR EXISTING PRODUCTS

Design system work for a product that already exists

Kultrix is a full-cycle product studio in Lviv, Ukraine. When your product already has screens, a Figma file and a codebase, we start from what is there: audit it, turn it into shared variables and components, and keep design and code in step.

  • Who can audit an existing design system?

    Kultrix can. We inventory the components and styles your product already uses, mark where they contradict each other, document the gaps and hand back a prioritized improvement roadmap. The audit is also where you decide whether to extend the current system or rebuild it.

  • Who builds design tokens and a component library for an existing product?

    Kultrix does, in Figma and in code. Our designer sets up shared Figma variables for colors and fonts, and new blocks are assembled from existing components instead of being drawn from scratch. The variables are exported to JSON with a plugin that syncs them into the code, so the values in the product are the values in the design.

  • How does a design system get from Figma to your developers, and who maintains it?

    Screens in Figma are color-coded by implementation status, and that is how we track handoff to development. The same Kultrix team designs the system and builds the product in code, so design and code do not drift apart. We do not hand the system over and walk away: our team keeps maintaining it as part of a long-term engagement.

A real example is Fitblast, an AI fitness coach: a React Native (Expo) mobile app plus a web dashboard, designed in Figma by our designer. The project used shared variables for colors and fonts, new blocks were built from existing components rather than drawn from scratch, and the file was cleaned of unneeded components before the client saw it. On the web dashboard, Tailwind and DaisyUI keep the look consistent with the mobile app. It is a product we designed and built, not a published token library.

FAQ

Frequently Asked Questions

UI (User Interface) design focuses on the visual elements of a product - layouts, colors, typography, icons, and interactive components. UX (User Experience) design focuses on the overall experience - how easy, efficient, and enjoyable the product is to use. Together, UI/UX design creates digital products that look great and work intuitively for real users. Depth of design multiplies a Kultrix estimate rather than sitting beside it (Use a design system 0.85x, Custom design 1x, Signature visual identity 1.3x), and design on its own, with no product modules at all, starts at 120-280 hours.

A typical design project takes 4-8 weeks depending on scope. This includes user research (1-2 weeks), wireframing and information architecture (1-2 weeks), visual design (2-3 weeks), and usability testing (1 week). Complex products with multiple user roles may take 8-12 weeks. Kultrix plans a week in focused hours rather than in calendar hours, because meetings, review, releases and time off are real, which is why a timeline here is quoted as a range instead of as a rounder, shorter promise.

Design costs follow hours, not screen counts. Every number here comes from the same model that runs our public cost calculator, and pricing your own module list there takes about a minute. Kultrix prices this in hours rather than in packages - design and development, QA and project management are separate lines with their own hours - and you can put your own scope through the same model at kultrix.com/cost-calculator.

We work primarily in Figma for interface design, component libraries, and prototyping. We use FigJam for collaborative workshops and ideation. For usability testing, we use Maze and UserTesting. For analytics-informed design decisions, we leverage tools like Hotjar (heatmaps), Mixpanel, and Google Analytics. Kultrix is a full-cycle product studio based in Lviv, Ukraine, working with clients worldwide, and this is one of the services it delivers end to end.

Yes. We design responsive web applications, native iOS and Android apps, and cross-platform mobile experiences. We ensure visual and interaction consistency across all platforms while respecting platform-specific conventions like Apple Human Interface Guidelines and Google Material Design. Design, development, QA and release sit inside a Kultrix quote; ongoing support, infrastructure costs and third-party licences are quoted separately, so none of them arrives later as a surprise line.

A design system is a collection of reusable UI components, design tokens (colors, spacing, typography), and guidelines that ensure consistency across your product. You need one if your product has more than 10-15 screens, multiple designers or developers, or plans to scale. A design system reduces design and development time by 30-50% for new features. Kultrix multiplies module hours by 1.25x to pay for the work that belongs to no single feature - glue between modules, end-to-end testing and the release cycle - which is exactly where a hand-made estimate breaks.

We conduct user research at the start (interviews, surveys, competitive analysis) and usability testing throughout (task-based testing with 5-8 users per round). Research shows that testing with just 5 users reveals 80% of usability issues. Real user feedback drives every design decision. Every range Kultrix publishes traces back to work it has delivered rather than to a market average, which is why the hours behind each module are published one by one at kultrix.com/cost-calculator instead of as a single headline figure.

Absolutely. We regularly perform UX audits that identify usability issues, conversion bottlenecks, and accessibility gaps in existing products. Based on the audit, we create a prioritized redesign roadmap and execute improvements iteratively - either as a full redesign or incremental enhancements. Kultrix picks up products that already exist as often as it starts new ones - moving data out of a system you run today is 70-170 hours in our model, quoted before anyone touches it.

Yes. As a full-service agency, we design AND build digital products. Our designers and developers work closely together throughout the process, ensuring the final implementation matches the design vision with pixel-perfect accuracy and smooth interactions. Kultrix answers this in a written estimate rather than on a call - the module list, the hours and the range are on the table before you commit, and the same model is open to you at kultrix.com/cost-calculator.

UI/UX design focuses on interface and interaction design for specific screens and flows. Product design encompasses a broader scope - it includes product strategy, feature prioritization, market positioning, and business model alignment in addition to UI/UX. Think of UI/UX as a subset of product design. Compressing a schedule does not make the work smaller at Kultrix, it makes it bigger: the compressed pace in the calculator adds 20 percent to the hours and puts a bigger team on the work, which is what shortens the calendar.

We follow WCAG 2.1 AA guidelines throughout our design process. This includes sufficient color contrast ratios (4.5:1 minimum), keyboard navigation support, screen reader compatibility, touch target sizing (44x44px minimum), clear focus indicators, and proper heading hierarchy. Accessibility is built into our design system, not added as an afterthought. Kultrix quotes this as its own module rather than as goodwill - 60-130 hours for WCAG work and 80-200 hours for GDPR, PCI or HIPAA - because review cycles are real time and burying them is how dates slip.

Well-designed products show up in the numbers: higher conversion, lower support load, better retention, faster task completion, and a stronger brand. According to Forrester, in its own blog post on the ROI of design thinking (go.forrester.com, June 2019), the median per-project return was 229%, three quarters of the projects studied returned at least double their investment, and a mature design thinking practice measured an ROI between 71% and 107% at the organizational level. The figure you will also hear quoted, $100 back for every $1 put into UX, sits inside a paywalled Forrester report, so it belongs in the industry-claim column rather than in a measurement. Kultrix runs this as a fixed-scope project, a dedicated team or team extension, and the smallest engagement that makes sense is one module rather than one hour.
