Frequently Asked Questions
Answers to the most popular questions
It depends on the product. For most business apps (delivery, booking, CRM client, loyalty) Flutter or React Native is optimal: one codebase, two stores, 30-40% savings. Native Swift or Kotlin is needed for heavy 3D, AR, video processing or deep NFC and Bluetooth integration. I help choose during the audit — see mobile development.
Cross-platform MVP takes 8-12 weeks. A complex product with custom backend, payments and integrations takes 4-6 months. Native apps for two platforms run 30-40% longer. I split the project into 2-week sprints: you see a working build every 14 days and can test on a real device.
Yes, the full cycle: Apple Developer and Google Play Console account setup, store page filling, screenshots, descriptions, ASO, passing Apple review. Apple often rejects for various reasons — I know most of the pitfalls and resolve them in 1-2 iterations, while newcomers can fail review for months.
The mobile world moves fast: new iOS and Android every year, new store rules, new screen formats. I offer an SLA contract: critical bugs in 4 hours, OS updates by priority, new features by separate estimate. Quarterly I run a performance and crash audit through Firebase Crashlytics.
Yes, that's a standard task. I connect REST or GraphQL API, sync data in real time, add push notifications through Firebase, single sign-on between site and app. If you don't have a CRM yet, I build it together with the app. See CRM, ERP and SaaS in Chernivtsi.
Simple MVP on Flutter or React Native starts at 7,000 USD. Business app with backend, payments and analytics costs 15,000-30,000 USD. Complex native products start at 40,000 USD. I give a fixed estimate after audit and split payment by sprints — convenient for Chernivtsi and Bukovyna mid-sized businesses.
Yes. I build a design system: typography, colors, components, icons, illustrations. I create a Figma prototype with all screen states, animation and microinteractions. I test UX on real users before development. I brand the app to your style — no Themeforest or UI kit templates.
HTTPS traffic encryption with certificate pinning, secure token storage in Keychain and Keystore, biometric authentication (Face ID, Touch ID, fingerprint), protection against reverse engineering, regular audits. For medical and financial apps I add GDPR compliance and Ukrainian personal data protection law as a baseline.
Yes. For tour agencies near the Town Hall and Turkish Square I build apps with tours, bookings, audio guides for the Metropolitans' Residence, maps of Kobylianska and Soborna, multi-language (UK, EN, RO, PL). I integrate with hotels, airlines and payment systems. For a website check web development in Chernivtsi.
Yes, cross-border trade is a separate app category. I build B2B portals for wholesalers, mobile apps for sales reps with offline orders, multi-currency systems (UAH, EUR, RON, MDL). For online cross-border sales see eCommerce in Chernivtsi.
Yes. I meet clients at cafes on Olha Kobylianska, the Chernivtsi IT Cluster space, near Universytetska and Soborna. The first meeting is free and lasts 60-90 minutes with an audit of your ideas and competitors in the App Store and Google Play. I work with businesses from Shevchenkivskyi and Pershotravnevyi districts.
Yes. Often a mobile app is the front-end for an existing accounting system. I connect 1C, BAS, Bitrix24, RetailCRM, Salesforce, Pipedrive and HubSpot via API. If there's no system, I build one on Node.js and PostgreSQL alongside the app. See CRM, ERP and SaaS.

Mobile App Development in Chernivtsi — Oleksandr Filyuk
Mobile Development for Chernivtsi
Chernivtsi is a mobile city. 265,000 residents, thousands of students at Yuriy Fedkovych Chernivtsi National University and Bukovinian State Medical University, a constant tourist flow through the Metropolitans' Residence, Town Hall and Turkish Square. They all open a smartphone every day to order coffee on Kobylianska, book a hotel, pay for Bukovyna wine or schedule a doctor's visit. If your business has no mobile app, you aren't present in the most important client touchpoint.
I'm Oleksandr Filyuk, 15+ years and 130+ launched products. I build iOS and Android apps on Flutter, React Native, Swift and Kotlin with backend on Node.js, PostgreSQL and Firebase. I work with businesses in Shevchenkivskyi and Pershotravnevyi districts and regularly meet clients at the Chernivtsi IT Cluster, cafes on Olha Kobylianska and spaces near Universytetska and Soborna.
Which stack fits your project
Cross-platform development on Flutter or React Native is the optimal choice for 80% of business apps. One codebase, two platforms, 30-40% savings. Fits delivery, loyalty, CRM clients, booking, B2B portals, medical accounts. Modern Flutter delivers near-native performance, and React Native is the best choice if you already have a React website.
Native development on Swift and Kotlin is needed for heavy apps: 3D visualization of Bukovyna wineries, AR tours of Kobylianska architecture, video processing, complex NFC, Bluetooth or camera work. I pick the stack at the audit — no dogma, purely your goals and budget.
What's included in the project
Every project starts with an audit: I study your business, App Store and Google Play competitors and successful samples in your niche. Then User Story Map, Figma prototype, design system, 2-week sprint development, real-device testing, store publishing, marketing assets (ASO optimization, screenshots, video).
I build backend on Node.js and PostgreSQL, integrate Firebase for pushes, analytics and crashes, AWS or Google Cloud for scalable infrastructure. I connect payments (LiqPay, Fondy, Stripe for international), delivery (Nova Poshta, Ukrposhta), maps (Google Maps, Mapbox), social login (Apple, Google, Facebook) and analytics (GA4, Firebase Analytics, Amplitude).
Integrations with accounting systems
Ukrainian business rarely starts from scratch — you already have 1C, BAS, Bitrix24, RetailCRM or Salesforce. I connect mobile apps to these systems via API and sync products, prices, stock and orders in real time. For Bukovyna winery sales reps or medical centers I add offline mode: data is written locally and synced when the network is back.
Security and compliance
Mobile apps mean personal data, payments, medical records and business secrets. I build security in from day one: HTTPS with certificate pinning, secure Keychain and Keystore storage, biometrics through Face ID, Touch ID or fingerprint, protection against reverse engineering and root/jailbreak. For medical apps I follow GDPR and Ukrainian personal data law. Regular post-launch security audit is part of the SLA contract.
Why Chernivtsi
Chernivtsi has a unique feature: an active tourism economy around Austro-Hungarian heritage, the UNESCO Metropolitans' Residence and pedestrian Kobylianska, plus cross-border trade with Romania and Moldova through Porubne and Mamornytsia. This creates a huge field for mobile products: audio guides, tour booking, B2B portals for exporters, multi-currency wallets, cafe loyalty programs. I know this context and build apps that resonate with local clients immediately.
How to start
Leave a request — I respond within a day, schedule a free meeting in Chernivtsi or on Zoom and spend 60-90 minutes analyzing the idea, competitors, stack and budget. After that you get a written proposal with a fixed estimate. If you need a CRM behind the app, see CRM, ERP and SaaS in Chernivtsi, for a website see web development, for an online store see eCommerce. Full service description is on the mobile development page.
