Answers to the most popular questions
The cost depends on product complexity, the number of platforms and the integrations required. Approximate ranges: an MVP app (one platform, 6–10 screens, basic backend, authentication) — starter package; a full product (iOS + Android, 20–30 screens, push notifications, payments, CRM integrations) — standard package; a complex product (real-time, video calls, geo logic, in-app purchases, multiple user roles, admin panel) — premium package.
Client geography doesn’t affect price: a business in Rivne, Kyiv or Los Angeles gets the same rates. Local entrepreneurs from the Rivne region who order an app together with a website or a CRM system get a combined package with significant savings. Exact numbers are discussed after discovery — without discovery any “price on the website” is usually inaccurate by ±50%.
This is the most common question for a Rivne business ordering an app for the first time. The answer depends on three factors: interaction complexity, budget, future plans.
At discovery I’ll look at your scenario and honestly say what will work better. Sometimes the answer is hybrid: backend and UI in Flutter, with a critical module (e.g. video calls) implemented natively via a bridge.
Yes. I meet clients from Rivne and the Rivne region in person at the discovery session — 2–3 hours where we discuss: business model, target audience, key use cases, technical constraints (which systems need to be integrated), monetisation (subscription, in-app purchases, ads, B2B), competitors in the Rivne region market and at national level.
The meeting can happen in your office (Soborna, Chornovola, Kyivska, Lonokombinat — anywhere in Rivne), or at a neutral place over coffee. Further work happens mostly online via Figma, GitHub, Slack/Telegram, with regular build demos. If you’re also planning branding — we combine discovery for both.
It depends on complexity, but typical reference points for Rivne businesses are:
The cycle includes: discovery (1–2 weeks), UI/UX design and prototype (3–4 weeks), iterative development (2-week sprints), QA, Apple and Google review (here delays of 1–7 days per platform are possible), release. I always plan a buffer for review — Apple loves to bounce apps for reasons like “not enough content”, “unclear sign-in”, “hidden IAP”, and that has to be anticipated at the design stage.
Publishing is a separate process that’s often underestimated. I take care of everything turnkey:
All of this is included in the standard development package, not as an extra.
Yes — I deliver the full cycle: frontend (the mobile app) and the backend (the server side). The stack depends on the project: Node.js + TypeScript, Python (FastAPI/Django), or PHP (Laravel) — I pick what’s optimal for the specific task. Database — PostgreSQL, MySQL or MongoDB. Hosting — AWS, DigitalOcean, Hetzner, or Ukrainian Cityhost for businesses that want data stored within the country.
If you already have a CRM/ERP system — the app integrates with it via API and a separate backend isn’t needed. If you’re also planning a website in parallel, the backend can be shared between the app and the web version — that’s the most economical scenario.
Push notifications are one of the most powerful retention channels, but only when set up correctly. I implement them via Firebase Cloud Messaging (FCM) for Android and Apple Push Notification Service (APNs) for iOS, with a unified backend API.
Capabilities I configure by default:
An admin panel for the marketer or owner — to send campaigns independently without a developer.
In-app purchases (IAP) — the standard monetisation mechanism for content, premium features and subscriptions inside the app. I implement them via StoreKit 2 on iOS and Google Play Billing on Android, with backend validation through App Store Server API and Google Play Developer API.
Regarding the commission: Apple and Google take 15–30% of every transaction that goes through IAP. This is mandatory for digital content and subscriptions inside the app — bypassing it is forbidden, otherwise the app gets blocked.
But there are exceptions where you can use your own payment system (LiqPay, Fondy, WayForPay for the Ukrainian market, Stripe for international):
At discovery I’ll help you choose a legally clean monetisation model for your case.
From my practice with the Rivne region’s business, I identify these categories:
Each category has its own integration, monetisation and ASO specifics. We discuss this in detail at discovery.
This is a critical question for any app that processes personal data — and that’s almost every app. The baseline checklist I implement by default:
For medical and financial products — additional requirements (HIPAA, PCI DSS), which we discuss separately.
Yes, updates are a standard process. Importantly: any release in App Store and Google Play must pass review. Apple — usually 24–48 hours, Google — 1–7 days. So a “2-hour hotfix” is impossible in mobile apps — unlike web development.
Ways to minimise risks:
In the post-release support package (60 days free) — response to critical bugs, crash-rate monitoring through Firebase Crashlytics and prompt fixes.
Yes, fully. Most of my clients are from Kyiv, Lviv, Odesa, the US and Europe — we work entirely online via Figma, GitHub, Slack/Telegram, Zoom. For Rivne businesses the “no meetings” format is also available: discovery via video call, brief via a structured questionnaire, build demos through TestFlight (iOS) and Internal Testing (Android), invoices and contracts — electronic.
If meeting in person is convenient — I’m in Rivne, we can do discovery face to face and immediately look at the specifics of your business. Most clients choose a hybrid: 1–2 in-person meetings at the start (discovery + prototype presentation), then fully online until release. It’s the most efficient format — we don’t waste your time and don’t slow down the project.

A mobile app for a business in Rivne and the Rivne region is no longer a “bonus to the website” — it’s a full-fledged sales and retention channel. In a city of 240,000+ residents and a strong small-and-medium business sector — from cafés on Soborna and Chornovola streets to manufacturers around Lonokombinat and IT startups — a mobile product often becomes the primary interface between the business and the customer. I’m Alex Filiuk, Senior UI/UX designer and developer with 15 years of experience, designing and building mobile apps for Ukrainian and international clients. My portfolio includes 20+ mobile projects — native iOS and Android, and cross-platform in React Native and Flutter.
This page is a complete guide for a business owner or CTO in Rivne planning to launch a mobile app. You’ll find: how to choose between native and cross-platform, how much it costs and how long development takes, how publishing in app stores works, which integrations are usually required, how to avoid the typical mistakes of outsourcing agencies, and why it pays off to choose a designer-developer with Rivne context rather than a remote team that has never seen your office.
The most common illusion I encounter at discovery with Rivne businesses: “make us a mobile version of the website, but as an app.” It doesn’t work — and here’s why. The mobile user in 2026 has completely different expectations from an app than from a website:
So the right strategy for a Rivne business is to design the mobile experience separately, from scratch, rather than “wrapping the website in a shell”. It’s more work upfront, but the result is a real product that lives in the customer’s pocket — not a ghost icon on the smartphone home screen.
I’m not religiously committed to a single technology — I pick the stack for the task, not the task for the stack. Main directions:
If your project includes not only an app but also web — we design the website and the app on a shared backend, saving 30–40% of the budget. If you need a full CRM/ERP system — the app becomes a mobile interface to it.
I work via a transparent process that all my clients have gone through — from those in Rivne to those in Kyiv, Los Angeles or Berlin. Each stage has a fixed deliverable that you see and approve.
The total cycle ranges from 8 weeks for an MVP to 6+ months for a complex product. If you have a tight deadline (e.g. release tied to a Rivne launch by a specific date) — at discovery we look at what can be parallelised and where scope can be cut without hurting quality.
A modern mobile app rarely lives in a vacuum — it’s usually integrated with 5–15 external systems. Here are the key categories I work with constantly for Rivne region businesses:
Over 15 years in product development I’ve seen dozens of cases where a business in Rivne or other Ukrainian cities invested in a mobile app and got a result that didn’t meet expectations. The most common reasons:
Mobile app development is an investment that must pay back. Before naming numbers, I always ask the client to do the economics: if the app brings 50 new clients per month with an average ticket of 1,500 UAH, payback may come in 6–12 months. If those numbers don’t add up — maybe a mobile app is not the priority right now, and it’s worth investing in a website and Google Ads.
Approximate ranges (exact numbers are in the “Pricing” block):
Possible engagement models: Fixed Price (fixed cost after discovery), Time & Material (hourly billing for projects with variable scope), Retainer (monthly support after release).
A mobile app is part of a product ecosystem. If you’re planning a serious launch, it’s worth looking holistically:
I work not only with Rivne region businesses. If you have offices in several Ukrainian cities or plans for regional expansion — we build a product that scales. Among other locations:
The full list is on the “Service Areas” page. Also see the project portfolio, where real mobile cases from various industries are presented.
If you have an idea or already have an MVP that needs improvement — fill in the contact form or write to email/Telegram. The first discovery consultation is free, up to 60 minutes. We’ll go through: what product you want to build, who needs it, what alternatives exist, how much it will roughly cost, and how soon it’s realistic to ship in App Store and Google Play.
I’m ready to build for your business in Rivne a mobile app that will live in the customer’s pocket — not among ghost icons. A product that works for your sales, retention and differentiation from competitors every single day.
