Answers to the most popular questions
An MVP app of 8-12 screens starts at a base tier, a full-featured product of 25-40 screens costs significantly more, and a corporate B2B app with custom logic is priced separately. I quote exact pricing after the brief and scope. More on the mobile app design service page.
MVP — 5-7 weeks, full product — 10-14 weeks. If you already have a design system or brand guide, faster. If the project is bilingual (UK/EN) and targets EU tourists travelling to the Carpathians, I add time for two-locale approvals.
Yes, both platforms. iOS follows Apple Human Interface Guidelines, Android follows Material Design 3. That means different navigation, different components, different typography. I do not produce a single universal mockup but design two versions that look native on their platforms.
Yes, I work with Flutter and React Native teams. In that case I know the constraints of cross-platform solutions and avoid animations or components that break in transfer. If you also need a promo website for the app, see web design in Ivano-Frankivsk.
Yes, the baseline is 5-8 interviews with potential users, competitor analysis and a customer journey. If you need deeper research (usability tests, quantitative surveys) that is a separate stage with its own budget. For Ivano-Frankivsk projects I often run interviews with Bukovel tourists or restaurant guests.
I always build an interactive Figma prototype. This lets you "click" the future app before developers start writing code. Especially useful for B2B apps where you need to show logic to an investor or manager. For tourism apps, I always test the prototype with real users.
WCAG 2.2 AA by default: contrast, tap target sizes, VoiceOver and TalkBack support, dynamic typography. Especially important for apps targeting older users (medical apps in partnership with IFNMU) or tourists with limited abilities.
Yes, with special attention: onboarding determines how many users reach core value, the paywall determines how many subscribe. For Ivano-Frankivsk startups and SaaS products I test several variants to find the converting version. It is often the difference between a project that lives and one that fades.
Yes, this is one of my core niches. I have built apps for tour operators routing groups to Bukovel and Yaremche, Carpathian guide services and guesthouse booking systems. I understand the specifics: offline mode in the mountains, map integration, UK/EN/PL/DE multilingual support for European guests.
Yes — ordering from cafes on Nezalezhnosti, table reservations near Rynok Square, hotel loyalty programs. I know how to make a fast check-in, how to integrate payments, how to design a menu so a guest reaches order in 3 taps.
Yes, corporate apps for field crews, inspection checklists, manager dashboards. The specifics differ here: offline mode at the wellhead, large tap targets (because of gloves), minimal colours. We often partner with teams that include engineers who graduated from IFNTUNG.
Yes, I have worked with education projects connected to Stefanyk PNU and other Precarpathian universities. Courses, tests, push reminders, student progress, communities. UX discipline matters here — the student must come back daily, not only before the exam. Details on the mobile app design service page.

Ivano-Frankivsk is a city of 238 thousand residents, but hundreds of thousands of tourists pass through every year on the way to the Carpathians — Bukovel, Yaremche, Hoverla. A mobile app for any Ivano-Frankivsk business has to handle that double flow: the local user who lives in the city every day, and the tourist who stays for 3-7 days. Across 15+ years and 130+ projects I have learned to design UX that works for both scenarios.
My portfolio includes apps for Carpathian tourism services, food ordering and table reservations for Ivano-Frankivsk HoReCa, B2B apps for regional oil & gas companies, education platforms tied to Stefanyk PNU and IFNTUNG, and startups from the Ivano-Frankivsk IT Cluster. All of these segments need a different approach: tourism — offline mode and multilingual support, HoReCa — speed and simplicity, B2B — reliability and security, education — motivation and retention.
I design iOS apps to Apple Human Interface Guidelines and Android to Material Design 3. This is not the same mockup with a different logo: it is fundamentally different navigation (Tab Bar vs Bottom Navigation), different components, different typography, different transition logic. For cross-platform projects on Flutter or React Native, I respect framework constraints from the start so developers face no surprises. WCAG 2.2 AA is the default, tap targets ≥44pt, VoiceOver and TalkBack support.
Stage 1: brief and user research — interviews with 5-8 potential users, competitor analysis. Stage 2: customer journey and information architecture. Stage 3: Figma wireframes — low fidelity, focused on structure. Stage 4: design concept and design system — colours, typography, components, states. Stage 5: final screens for iOS and Android. Stage 6: interactive Figma prototype. Stage 7: developer handoff — specs, assets, answers to dev questions.
A tourist on a Bukovel cable car with gloves and weak signal — needs large tap targets, offline mode, cached maps. A restaurant guest on Nezalezhnosti before ordering — quick menu access, one-tap payment, order history. An engineer on an oil & gas site wearing safety gloves — minimal colours, large fonts, offline checklists. A PNU student before an exam — push reminders, progress bar, gamification. Each scenario requires its own UX solution, and I plan for them from day one.
An app is an extension of the brand, not an isolated product. That is why I often work with clients on a full cycle: identity first — see logo design in Ivano-Frankivsk, then website — web design in Ivano-Frankivsk, then the mobile app. This guarantees brand consistency across every touchpoint.
