What you get

  1. React Native & Expo

    TypeScript throughout, React Navigation, and shared patterns with your web codebase where it makes sense.

  2. Offline & Performance

    Local storage, background sync, and smooth animations so the app feels fast in real-world conditions.

  3. Push & Deep Links

    Notifications, universal links, and in-app flows that connect mobile to your web product.

  4. Store Submission

    TestFlight, internal tracks, metadata, and support through Apple and Google review.

Built for

  • Products launching on iOS and Android together
  • Teams extending an existing web product to mobile
  • Apps that need offline or field-use reliability
  • Consumer products with subscriptions or in-app purchases

Common questions

Yes. Our engineers are based in Lviv and Kyiv and deliver React Native apps for clients across Europe, the UK, and the US with predictable weekly releases.

We default to Expo for speed and OTA updates, and use config plugins or native modules when the product requires it.

Yes. We join brownfield codebases for new features, performance work, and store release support.

Most cross-platform MVPs land in 8–16 weeks depending on auth, payments, offline flows, and store submission requirements.
