Frequently asked questions
UX (User Experience) is about the overall experience: how easy is a product to use, how logical is the flow? UI (User Interface) is the visual layer: typography, color, icons, layout. Good design combines both: beautiful and user-friendly.
We work exclusively with Figma. It's the industry standard for UI/UX design, offers excellent real-time collaboration and makes developer handoff via Figma Dev Mode easy. Adobe XD is available on request.
A typical project takes 4 to 10 weeks, depending on scope. A single-product redesign is faster than a completely new platform. We always deliver a detailed timeline upfront.
Absolutely. We start with a UX audit: we analyze your current product for usability issues, accessibility and conversion losses. You get a report with concrete improvement points, then we get to work.
Yes, for any substantial project we build a design system: components, tokens, styles and documentation in Figma. Your designers and developers can then continue developing independently and consistently.
We use structured user interviews, clickable prototypes presented to real users and remote usability tests via tools like Maze or UserTesting. The findings are translated directly into concrete design decisions — ensuring the final product matches your target audience's expectations.
