Mobile App Development Agency — Ukraine

Codevia is a mobile app development agency based in Ukraine. We build iOS and Android apps in Flutter and React Native for clients across Europe and North America. Our team combines technical depth, convenient timezone, and the transparency you expect from a genuine partner.

We do not trade in grand marketing language — we deliver: real apps in the App Store and Google Play, technical decisions with clear rationale, and consistent communication throughout the project cycle.

What We Build

Cross-Platform Apps with Flutter

Single codebase, native performance on iOS and Android. Clean Architecture, BLoC state management, automated testing, and CI/CD pipelines.

React Native Applications

JavaScript and TypeScript, shared patterns with React web. Ideal for teams with existing web developers or products spanning mobile and web.

MVP and Product Validation

From concept to first public release in 8–14 weeks. We help choose the right initial scope and avoid over-engineering at the early stage.

B2B and Enterprise Tools

Field operations apps, role-based access, offline sync, and corporate system integrations. Security and auditability are built in from day one.

Consumer Products

Marketplaces, fintech, health and fitness, social apps. Push notifications, in-app purchases, onboarding flows, and retention mechanics.

Why Codevia

  • Ukrainian Team with Proven Track Record

    Our developers in Ukraine have real production experience — not just course certificates. We have navigated hard technical challenges and know where the risks are.

  • Convenient Timezone for Europe, US & Canada

    UTC+2/UTC+3 gives full working-day overlap with Central and Eastern Europe, plus 4+ hours of daily real-time overlap with US East Coast and Canada every afternoon (our PM is your AM). Same-day responses — no waiting overnight.

  • Specialization Over Breadth

    We specialize in Flutter, React Native, React/Next.js, and .NET. We do not try to take any project that comes our way. This means deeper expertise and better outcomes for your specific technology choices.

Frequently Asked Questions

Ukrainian developers offer a combination that is hard to find elsewhere: strong technical education, extensive production experience, European timezone alignment (UTC+2/UTC+3), and competitive rates compared to Western Europe or North America. Ukraine has produced internationally recognized engineering talent for decades.
We work asynchronously through a shared project management tool (Linear or Jira), hold weekly video calls, and provide written sprint summaries. You see every task, estimate, and blockers in real time. We do not disappear for a week and surface a finished feature — we involve you throughout.
We use Flutter and React Native to deliver both platforms from a single codebase. This is cost-effective for most projects. When a client requires fully native apps (Swift/Kotlin), we scope that separately — it is not our primary offering.
All IP is fully transferred to the client upon final payment. We sign NDAs before project kickoff. Source code repositories are transferred to your organization on completion or progressively during development.
Yes. We offer ongoing maintenance retainers covering OS updates, dependency upgrades, bug fixes, and minor feature iterations. We have clients whose apps we have maintained for over two years post-launch.
