A word from the Head of Design
“Good design isn’t about the “wow” — it’s about a person understanding your offer in seconds and clicking the button. We draw every screen around a specific user action — that’s why our products don’t just look good, they work.

Questions and answers
How much does app design cost?
A UX audit of an existing app from $2,000, full UI/UX design from $8,000, a mobile design system from $12,000. We price by screens and flows, not “pages”.
Should iOS or Android be designed first?
It depends on the audience and budget. Usually we design to native guidelines for both platforms at once from a single design system.
How is app design different from website design?
Different patterns (gestures, navigation, states), native iOS HIG / Material guidelines, screens instead of pages, and asset handoff for mobile development.
How long have you been in the market?
We’ve worked since 2011. Over 14+ years — 50+ projects for clients from 18 countries, a team of 13 specialists.
How do you work if the client is in another city?
Fully remote: Zoom/Google Meet for alignment, shared Figma boards and a task tracker. Geography doesn’t affect quality or timelines.
How is the relationship with the client formalized?
A contract + spec with a fixed scope, timeline and budget. Transparent, with milestones and acceptance points.
Do you provide progress reports?
Yes — after every stage: what’s done, what’s next, a demo in Figma. No “black box”.
