Mobile Development in Ivano-Frankivsk — iOS, Android, Cross-Platform

A simple cross-platform MVP on Flutter or React Native takes 6-8 weeks of work. A complex product with native modules in Swift and Kotlin, a backend, integrations and an admin panel — 4 to 6 months. At the kick-off meeting we draft the screen list, user flows and integrations, after which I provide a transparent sprint-by-sprint estimate. You pay per module and every two weeks see a build in TestFlight or Firebase App Distribution. No surprise +30% at the end — everything is agreed upfront.

It depends on the product. For a typical business app with forms, lists, chat and payments, Flutter or React Native is optimal: one team, one codebase, two stores. For apps with heavy graphics, AR, video processing, BLE peripherals or strict offline requirements, I choose Swift for iOS and Kotlin for Android. I often deliver hybrids: 80% of screens cross-platform, critical modules native. I will help you pick the stack at discovery, without religious wars.

Yes — the backend is half the success of any mobile product. I build it on Node.js and PostgreSQL with GraphQL and REST APIs, authentication, push notifications, integrations with your CRM and ERP. For fast MVPs I often use Firebase: Auth, Firestore, Cloud Functions, Realtime Database, Push, Crashlytics. Hosting on AWS, Google Cloud or your own server. If you already have a CRM/ERP, I plug the mobile app into it as another API client.

I do. We can launch from my developer account, but the right way is to create your corporate Apple Developer account ($99/year) and Google Play account ($25 one-off) so that the app belongs to your company. I prepare screenshots, descriptions, keywords in Ukrainian and English, metadata, and configure in-app purchases if needed. I shepherd the app through Apple review and respond to reviewer comments. Releases are routine for me — dozens per year.

Push goes through Firebase Cloud Messaging (FCM) for Android and APNs for iOS — free and stable. Segmentation lives on the backend: you can target push to specific cohorts, geos or behavioural segments. Analytics — Firebase Analytics plus custom events flowing into your BigQuery or PostgreSQL to feed product metric dashboards: retention, DAU/MAU, time to conversion. I plug in Sentry or Crashlytics for crash tracking. You see the real picture, not just download counts.

Yes, this is a typical task. I integrate apps with Bitrix24, RetailCRM, Salesforce, Pipedrive, HubSpot, 1C and BAS via REST/GraphQL APIs. If your CRM has no public API, I build a Node.js middleware that listens to its database or webhooks and exposes clean endpoints for the mobile client. For Carpathian oilfield crews, for example, I sync 1C field tickets into the foreman's mobile app in real time. Details in CRM development.

TLS for all traffic, certificate pinning for critical APIs, secure token storage in Keychain (iOS) and EncryptedSharedPreferences/Keystore (Android), 2FA and biometrics (Face ID, Touch ID, fingerprint). Sensitive data is never kept in plain text on the device. For medical and fintech projects, I run a separate security audit before release. Everything aligns with GDPR, App Store and Google Play privacy guidelines, and Ukrainian personal-data protection law.

After release I do not vanish. iOS and Android ship new versions every year — the app needs adapting, otherwise in 1-2 years it will simply fail review or stop working on new devices. I offer an SLA with regular updates, crash monitoring through Crashlytics or Sentry, and A/B testing via Firebase Remote Config. Once a quarter we review product metrics and propose new features. About 60% of my Ivano-Frankivsk clients have been with me for 3+ years.

Yes — Carpathian tourism is one of the most exciting directions. I have shipped apps with offline trail maps, accommodation booking in Polyanytsya and Mykulychyn, ski-pass and rental integrations, push notifications about weather and avalanche risk. For hotels and guesthouses I build apps with booking management, QR check-in and loyalty programs. Such apps are often integrated with Next.js websites — see web development in Ivano-Frankivsk.

Yes, very much so. A field crew servicing wells and pipelines in the Carpathian foothills does not carry a laptop around. They need a phone with offline mode, photo capture of work, GPS tracking and electronic ticket signatures. I build such apps on Flutter with SQLite caching and sync when network appears. Integration with 1C, BAS and the central ERP. Many of my clients in this segment are graduates of the Ivano-Frankivsk National Technical University of Oil and Gas.

Discovery — 1-2 offline meetings in central Ivano-Frankivsk, near Rynok Square or at your office on Nezalezhnosti Street. Then we run two-week sprints: a Zoom demo at the end of each, minutes in Notion, new tasks in Linear or Jira. Design happens in Figma with a clickable prototype. Test builds reach TestFlight and Firebase App Distribution immediately — you install the app on your phone and give feedback. Transparency at every stage, no wait-we-are-still-working moments.

Honest answer — not always. A small cafe or salon is often better served by a website and social media presence — see digital marketing and SEO. A mobile app pays off when there are repeat purchases (delivery, a cafe with loyalty), a complex service (tourism, medicine), field crews or a meaningful audience of several thousand users. At discovery I will honestly tell you if you do not need an app yet, and suggest cheaper alternatives via PWA or a Telegram bot.
