Mobile App Design in Khmelnytskyi — iOS, Android, Flutter

Cost depends on scope: number of screens, logic complexity, research needs. A simple business-card app with 8-12 screens — lower segment of my pricing. A medium app (e-commerce, ordering service, fitness tracker) with 25-40 screens and a design system — middle segment. A complex B2B product or SaaS with 60+ screens, custom features, integrations — custom quote. Free 30-minute consultation at the start — exact pricing after the brief.

Simple app — 3-4 weeks. Medium — 6-8 weeks. Complex B2B product — 2-4 months. Schedule: week 1 — UX research and CJM, weeks 2-3 — wireframes and information architecture, weeks 4-6 — UI design and design system, week 7+ — interactive prototype, testing, finals. I work in 1-week sprints, Figma demos weekly. This allows early course corrections without late rework.

I'm a UI/UX designer, I don't do development myself. But I work with vetted developers from the Khmelnytskyi IT Cluster who build apps on native platforms (Swift for iOS, Kotlin for Android) and cross-platform (Flutter, React Native). I can take the full cycle as a project manager — from design to publishing on App Store and Google Play. Or hand off the design to your team — Figma Dev Mode with tokens for Swift/Kotlin/Flutter makes this painless.

Depends on business goals. If audience is B2C in Ukraine, where Android dominates (~70%), and budget is limited — Flutter or React Native. If audience is premium B2C or export to US/EU, where iOS share is higher — native iOS+Android. If it's a B2B app for internal team (e.g., warehouse at the «7th kilometer» market) — cross-platform is enough, saves 30-40% budget. At the consultation I'll help you decide considering your audience and resources.

Yes, a design system is a mandatory artifact for any app with 15+ screens. It includes: tokens (colors, typography, spacing, shadows, corner radii), component library (buttons, fields, cards, modals, nav bars), typical patterns (lists, forms, onboarding), dark theme. I build on Material Design 3 principles for Android and Apple HIG for iOS, with a custom brand layer on top. Learn more on the mobile app design page.

Yes, every app of mine supports dark mode by default — not as «added later» but as part of the design system from the start. I define colors via tokens (e.g., surface-primary, text-primary) with two versions: light and dark. Dynamic Type on iOS and font scale on Android are also standard: text scales from 80% to 200% without breaking layout. This is part of WCAG 2.2 AA and Apple/Google platform requirements.

Yes, onboarding is critical for retention. The standard — 3-5 screens explaining key benefits (not features!), non-blocking, with skip option. I design push notifications by «less is more» principle: only valuable ones (new orders, reminders, behavior triggers), segmented by user behavior, with thoughtful tone and CTA. I integrate with systems like OneSignal, Firebase, Braze. This is part of a complete UX flow, not a separate service.

Yes, redesigns are 30% of my mobile projects. I start with an audit: analytics (Firebase Analytics, Amplitude), heatmaps, user interviews, competitor review. I identify weak UX points (where users get stuck, where churn happens), strong points (what to keep), new opportunities (features that add value). Often a redesign delivers 20-40% retention and conversion growth without ad spend. Best ROI — for apps with 1+ year in market and an active user base.

Yes, this is one of my niches. The «7th kilometer» wholesale market is hundreds of B2B operators working with dealers from across Ukraine and CIS. Specific apps are needed: catalogs with wholesale prices, ordering with size-grid selection (clothing, footwear), CRM and warehouse integration, manager chat, push notifications for new arrivals. I've designed 4 such apps. If you also need a web catalog — see web design in Khmelnytskyi.

Yes, the Podillia agrarian sector is a large and under-digitized niche. I've designed apps for farmers and agro-holdings: field tracking, equipment GPS monitoring, treatment journals, weather forecasts, exchange prices. The specifics — users aren't «digital», they work in the field (need large fonts, mistap protection, offline mode, simple onboarding). I often integrate with IoT devices and sensors via Bluetooth.

Yes, after final payment I hand over all files: Figma project with design system, prototype, specifications. I add developers to Figma Dev Mode — they see tokens, spacing, asset export in needed formats and sizes (1x, 2x, 3x for iOS; mdpi/hdpi/xhdpi/xxhdpi for Android). Economic rights to the design transfer to you per contract. If you also need branding — see logo design in Khmelnytskyi.

I live in Khmelnytskyi, so we can meet in person — at my office or yours. For remote clients — Zoom and Google Meet. Ongoing communication — Telegram or Slack. All edits and comments — directly in Figma on specific screens and components. Weekly — status update with video demo of interactive prototype. I'm available during Kyiv +2 work hours, responding within 2-4 hours on weekdays. Details on the service page.
