Software studio · Prague, Czech Republic

We build mobile, desktop and web applications

Reactive Studio is a development studio based in Měšice, just outside Prague. Since 2018 we have been designing, building and maintaining iOS and Android apps, native macOS software, websites and e-commerce projects — for startups, established companies and international brands.

What we do

Mobile apps

Native iOS (Swift, SwiftUI) and Android (Kotlin) development, plus cross-platform React Native when it makes economic sense. From MVP to App Store and Google Play release, including review management.

macOS apps

Native macOS applications are our specialty — we build and ship our own products (FocusForge, CopyForge, DiskForge) sold worldwide, and we bring the same expertise to client projects.

Websites & e-commerce

Fast, SEO-friendly websites and custom e-shops (PrestaShop, WooCommerce, Next.js), including integrations with Czech payment, accounting and comparison-shopping services.

AR & Unity

Augmented-reality experiences and games built with Unity, ARKit and ARCore — including large retail campaigns with 3D content, animation and sound production.

AI integration

RAG chatbots, AI agents connected to company systems, and LLM-powered product features — designed with a pragmatic eye for what actually pays off.

Backend & cloud

Custom backends in Go and Node.js, cloud infrastructure on Google Cloud and AWS, CI/CD pipelines and long-term operations — we run what we build.

Selected work

  • Sportsman — a social app for 70+ sports (iOS & Android, React Native, custom Go backend on Google Cloud).
  • Spookies for Kaufland — an AR retail campaign app with 48 animated characters, built in Unity with ARKit/ARCore.
  • Hokejová knížka — an AR companion app for a book about Czech ice-hockey legends, featuring a digital reconstruction of the former Štvanice winter stadium.
  • FocusForge, CopyForge, DiskForge — our own native macOS productivity apps, localized into 20 languages and sold on the Mac App Store and directly.

Detailed case studies are available in Czech in our references section — we are happy to walk you through them in English on a call.

How we work

  1. Free initial consultation (60–90 min) — video call or in person in Prague. No commitment.
  2. Written proposal within a week — detailed budget, timeline and technical approach.
  3. Development in two-week iterations — regular demos, your feedback shapes the product.
  4. Release and hand-off — store publication, documentation, source code.
  5. Long-term support — monthly retainer or ad-hoc, your choice.

Typical budgets: a single-platform MVP starts around CZK 300,000 (approx. EUR 12,000); a full cross-platform app with a custom backend ranges from CZK 600,000 to 1,500,000 (approx. EUR 24,000–60,000). We publish our pricing openly — see the price list (in Czech).
