Answers to the most popular questions
MVP app (10-15 screens) — from $4500, mid-size product (20-40 screens) — from $9000, complex app with custom flows — from $15000. The price depends on the number of screens, UX complexity, two platforms (iOS + Android), design system depth. Details on the service page.
MVP — 6-8 weeks, mid-size product — 10-14 weeks, complex app — 16-20+ weeks. Stages: research (1-2 weeks), information architecture and wireframe (2-3 weeks), visual design and design system (3-6 weeks), prototype and testing (1-2 weeks), final and handoff (1-2 weeks).
Yes, separate mockups for iOS (Apple HIG) and Android (Material Design 3). This is not one design with small tweaks — guidelines differ in navigation, typography, interaction patterns. If the budget is tight, we can start on one platform (iOS or Android) and add the second after MVP. Often this is smarter for hypothesis testing.
I hand off design to native iOS (Swift) and Android (Kotlin) developers, as well as Flutter and React Native teams. I have trusted contractors in Cherkasy and Kyiv — I will pick by budget and complexity. If you already work with a team — I integrate into their process: Jira, Linear, Notion, Figma with documentation.
Yes, at the prototype stage I run 5-7 user tests — moderated or unmoderated, with real users from your audience. In Cherkasy I often test with local clients via Maze or UserTesting. Result — a report with found problems and recommendations. This saves tens of thousands on post-release rework.
I build a full design system in Figma: tokens (colours, spacing, typography, shadows), components (buttons, cards, forms, navigation), patterns (onboarding, checkout, profile screens). All as components with variants, with documentation. This allows scaling the app further and adding new screens without quality loss.
Yes, I prepare visual materials for App Store and Google Play pages: icons in all sizes, captioned screenshots, preview videos, banners. I also consult on texts, keywords and screenshots — what actually converts installs. Actual launch and promotion is a separate process with an ASO specialist.
Yes, accessibility at WCAG 2.2 AA level is a standard, not an option. I check contrast, touch target sizes, dynamic type (Dynamic Type on iOS, font scale on Android), VoiceOver/TalkBack scenarios. This is especially important for apps with a broad audience — from youth in Sosnivka to older generations using smartphones.
Yes. In Cherkasy DTC retailers actively launch loyalty apps, agro companies digitise field tracking and logistics, delivery services cover Sosnivskyi, Prydniprovskyi and Mytnytsia. I know local audience behaviour: which traffic is mobile, which payment methods (Apple Pay, Google Pay, Privat24) are common, which marketing channels work.
Yes, my 130+ projects include cases for Cherkasy businesses: B2B agro tools, e-commerce apps of regional retailers, educational platforms. I will show specific cases on a call — some under NDA. If you also need a site or identity — we combine into a single product project with web design.
Yes. I meet in coworking spaces on Shevchenka Boulevard, near Soborna Square, at your office. Many owners choose online via Google Meet — faster and not dependent on Khreshchatyk traffic or Dnipro embankment weather. The brief can be hybrid: one offline and several online stages.
Yes — Progressive Web App (PWA) or cross-platform with Flutter / React Native. I help choose: for simple flows (catalogue, promos, profile) PWA is often enough and much cheaper. For complex B2B agro tools or financial services — native or Flutter. We choose together based on budget, timeline and features.

| Dev handoff | Documentation + support | File and silence |
| Accessibility | WCAG 2.2 AA, dynamic type | No checks |
I am Oleksandr Filiuk, a designer with 15+ years of experience and a portfolio of 130+ projects. I design UX/UI of mobile apps for Cherkasy businesses — from MVP startups to complex B2B tools. For me an app is a product with its own logic, patterns and metrics. Not a mockup with pretty screens but a tool that generates business results.
Cherkasy is a growth point for mobile products. Regional retailers launch loyalty apps to compete with Kyiv. Agro producers of Cherkasy region digitise field tracking, logistics and farmer communication. Delivery services cover Sosnivskyi, Prydniprovskyi, Mytnytsia. IT teams from Cherkasy IT Cluster build SaaS products for global markets.
Catalogue, cart, payment (Apple Pay, Google Pay, Privat24), delivery (Nova Poshta), profile, promo push notifications. Budget — from $6000, timeline — 8-12 weeks. Suitable for regional retailers of Cherkasy region.
Field tracking for agro, logistics, mobile CRM, tools for field staff. Complex flows, tabular data, offline mode. Budget — from $9000, timeline — 12-16 weeks. Have worked with agro and processing.
Delivery, booking, appointments, loyalty. Fast onboarding, minimum steps to result. Budget — from $5000, timeline — 6-10 weeks.
Courses, tests, progress, gamification. Suitable for educational projects and universities — Bohdan Khmelnytsky University, Cherkasy State Tech. Budget — from $7000, timeline — 10-14 weeks.
Interviews with the owner and 5-7 potential users. Analysis of 5-10 competitors — Ukrainian and international. Audience map, key jobs-to-be-done, hypotheses.
Screen map, transition logic, main flows. Wireframe prototype in Figma — no visuals, just logic.
Separate mockups for iOS (Apple HIG) and Android (Material Design 3). Full design system: tokens, components, patterns. Documentation.
Interactive Figma prototype. 5-7 user tests via Maze or UserTesting. Report with issues and recommendations. Refinement.
Figma documentation, specifications, video explanations of complex animations. Support during development — I answer questions and verify implementation.
Apple HIG and Material Design 3 are different systems. iOS uses gesture-based navigation and tabs, Android — bottom bar and floating action button. Fonts, spacing, shadows, form patterns — all differ. A single design for both platforms looks foreign and hurts conversion. I do separate mockups but save time through a shared design system.
Design — Figma with a full design system. Prototyping — Figma Prototype or ProtoPie for complex interactions. Testing — Maze, UserTesting, Lookback. Documentation — Notion. Development — Swift (iOS), Kotlin (Android), Flutter, React Native. Accessibility — WCAG 2.2 AA, Dynamic Type, VoiceOver, TalkBack.
Leave a request or write in Telegram. The first call is free, 30 minutes about the product, goals, deadlines. I will give an honest estimate: full native app or PWA / cross-platform. If you plan a site or identity — we combine into one product project. Meetings online or in Cherkasy: coworking on Shevchenka Boulevard, near Soborna Square, at your office.
