Answers to the most popular questions
It depends on scope and platforms. Approximate ranges I work with on the Kyiv market:
Exact pricing is in the “Pricing” block above. The Kyiv market has higher rates than regional cities, but I keep prices below EPAM/GlobalLogic-tier because I work personally without multi-layer agency overhead.
This is a product, not a technical decision. I recommend starting from three questions:
In a product strategy workshop we lock the choice with reasoning in 1 day.
Yes. For Kyiv projects I usually meet in person at key milestones: kickoff (brief, scope), UX presentation (Figma prototype and clickable flow), UAT (beta builds via TestFlight and Google Play Internal Testing), release readiness (before store submission). Meetings are convenient in Podil (Unit.City), Pechersk (BC Astarta-Kyiv, Gulliver) or your office.
Between milestones we work online: weekly demos in Zoom, Slack/Telegram for operational comms, Figma + Linear/Jira for design and tasks. It’s a hybrid format that doesn’t waste time on Khreschatyk traffic and doesn’t deprive you of personal contact with the executor. Most teams in Kyiv choose exactly this format.
The standard cycle is 3–6 months for a full product, 6–10 weeks for an MVP. Stages:
For native iOS apps — standard modern stack:
If you already have a web part — we sync the stack with web development.
On Android — also a modern native stack:
For cross-platform — mostly React Native (TypeScript + Expo or bare workflow) or Flutter (Dart 3 + Riverpod/Bloc) — chosen by product specifics and team.
Depends on the client situation:
If the project includes a CRM/SaaS part — we sync the mobile client with the admin web cabinet.
I take the full submission cycle on myself — it’s a separate competence often underestimated in Kyiv:
Kyiv startups often get stuck exactly at this stage. I shorten this path to 1–2 weeks instead of 1–2 months of failed submissions.
ASO (App Store Optimization) is the optimisation of the app’s store page for organic traffic. Analogue of SEO, but for App Store and Google Play. I do basic ASO as part of publishing:
Deep growth ASO with constant experiments is a separate service worth discussing on its own.
The Kyiv mobile development market has three main competitor categories:
I’m a Senior practitioner with 15 years of experience who personally runs a project from product strategy to release and ASO. No intermediate PMs, no handover to juniors. It’s a format effectively absent in my price segment in Kyiv.
A modern product without correctly set up payments loses 30–50% of revenue right at launch. I close the entire payment side:
If you plan to monetise via subscription — bake the architecture in from the start, otherwise you’ll have to redo both the logic and the paywall UI later.
Yes. Not every project is full-cycle:
You get the most value from a full cycle — but we flexibly adjust the scope to your resources.
Comparison with other options
| Alex Filiuk | Large Kyiv outsourcing agency | |
|---|---|---|
| Meetings in Kyiv (Podil, Pechersk, Unit.City) | ✅ In person at kickoff and key milestones | 📋 Via account manager, not with engineers |
| Who runs the project | ✅ Senior with 15+ years, personally | ⚠️ Junior+Middle team with PM as a layer |
| Design and code in one cycle | ✅ One accountability stack | ❌ Design dept vs Dev dept |
| Native iOS (Swift/SwiftUI) | ✅ SwiftUI + Combine, async/await | ✅ Yes, but often 2-3x more expensive |
| Native Android (Kotlin/Compose) | ✅ Kotlin + Jetpack Compose, Coroutines | ✅ Yes, but slow team onboarding |
| Cross-platform (RN / Flutter) | ✅ Chosen by metric, not by trend | 🔄 Pushed by team availability, not fit |
| In-app purchases (StoreKit 2 / Play Billing) | ✅ Including server-side validation | 💰 Separate module, separate budget |
| Push (APNs/FCM) and analytics | ✅ Firebase / Amplitude / RevenueCat included | 📋 Separate SOW |
| App Store / Google Play submission | ✅ I handle review communication | ⚠️ Often dumped on the client |
| ASO (App Store Optimization) | ✅ UA + EN, screenshots, keywords, listing | 💰 Separate vendor service |

Kyiv is the largest and most demanding mobile market in Ukraine. Over 3 million capital residents plus 1 million in the metro area form an audience that uses monobank, Privat24, Rozetka, Glovo, Bolt, Kyivstar TV, Diia and dozens of other product-grade apps every day. If your mobile product targets a Kyiv audience, it is automatically benchmarked against these apps — by startup speed, animation smoothness, payment reliability, onboarding stability and push notifications. That means one thing: “just shipping something” is no longer enough. A Kyiv user deletes a buggy, slow or awkwardly designed app within 30 seconds. I’m Alex Filiuk, Senior UI/UX designer and product developer with 15+ years of experience and 30+ mobile apps in my portfolio for Ukrainian and international clients. This page brings together everything a business owner, product manager or CTO in Kyiv should know before starting mobile app development — from platform and stack choice to store submission and ASO.
Kyiv isn’t just a “big city.” It’s a tier-1 market with its own mobile consumption culture, very different from Lviv, Odesa, Dnipro or Kharkiv. Key specifics I account for in every Kyiv project:
So a Kyiv mobile project must be approached differently than a regional one. If you’re building an app that starts in Kyiv and then expands to other cities and countries — set up the right architecture from day one. Otherwise you’ll pay for tech debt many times over later.
This is the very first and most important technical decision in the project. A mistake at the start costs hundreds of thousands of UAH in rework 6–12 months down the line. So I begin every project with a tech-discovery workshop, where we choose the stack together based on your product goals, budget and team.
In a product strategy workshop we lock the choice with reasoning. If there’s no UX yet — we start with mobile app design, validating technical assumptions in parallel.
I work via a transparent process all my clients have gone through. Each phase has a fixed deliverable you can review. No “trust the team, in 4 months it’ll be beautiful.”
On the Kyiv market, an app without correctly set up monetisation loses 30–50% of revenue right at launch. I close the entire payment architecture:
If you plan serious monetisation — be sure to launch paywall conversion optimisation early on.
Push is the #1 retention tool in Kyiv. A well-configured push flow lifts D7 retention by 15–25%. A misconfigured one triggers mass uninstalls.
Kyiv startups often get stuck on submission: 1–2 months of rejects, rework, appeals. I take this part on myself:
ASO (App Store Optimization) is SEO for apps. In Kyiv, good ASO drives 30–60% of organic installs. Basic ASO is part of the publishing flow:
The Kyiv mobile development market is the toughest in Ukraine. I understand who I compete with and why clients pick me:
My positioning — Senior practitioner with 15 years experience in a boutique partnership format. I personally lead a project from discovery to release. No intermediate PMs, no handover to juniors, no “let’s add two more developers.”
My portfolio has 130+ projects, of which ~30 are mobile apps. Among them — fintech, e-commerce, on-demand, healthtech, corporate CRM apps. I’ve worked with Kyiv startups, with teams from the USA (New York, Los Angeles), Europe (Berlin, London). The most relevant cases for the “mobile development” category are shown in the “Featured projects” block above — examples of both consumer apps and enterprise CRM on mobile.
If you want concrete examples — go to the projects page or contact me via the contact form: I’ll pick 5–10 cases for your niche and show not only the result but also the working process — discovery notes, design iterations, architectural decisions.
Mobile development is part of a full product cycle. In Kyiv, a complex approach is often required:
I work not only with Kyiv clients. If you have offices in several cities or scale regionally — we’ll build a system that works everywhere. Among other locations:
The full list of locations is on the “Service Areas” page.
If you have a specific request — fill in the contact form or write to email/Telegram (contacts in the website footer). The first consultation is free, up to 60 minutes long. We’ll discuss your product, goals, budget, approximate timeline. After that I’ll send a detailed proposal with a fixed price for the discovery phase and transparent T&M for further stages.
I’m ready to build a mobile app for your business in Kyiv that withstands comparison with monobank, Glovo and Rozetka — and becomes a tool of growth for sales, retention and LTV for years. Not “another app in the store,” but a working product.
