Reactive Studio s.r.o.

Reactive Studio is a software development studio based in Měšice, just outside Prague, Czech Republic. Since 2018 we have been designing, building and maintaining mobile, desktop and web applications for startups, SMBs and enterprise clients.

What we do:

- Mobile apps — native iOS (Swift, SwiftUI) and Android (Kotlin), plus React Native when it makes economic sense. From MVP to App Store and Google Play release, including review management.
- macOS apps — our specialty. We build and ship our own products (FocusForge, CopyForge, DiskForge) sold worldwide, and bring the same expertise to client projects.
- Websites and e-commerce — fast, SEO-friendly sites and custom e-shops (PrestaShop, WooCommerce, Next.js), including integrations with Czech payment, accounting and comparison-shopping services.
- AR and 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.
- Cloud and DevOps — backends on Google Cloud and AWS, Kubernetes, APIs, serverless, CI/CD, monitoring and long-term maintenance.

Selected work:

- Sportsman — a social app for 70+ sports (iOS and 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 and ARCore.

How we work: we start with analysis and a written estimate, build in short iterations you can see running, and stay on for long-term support. We write code that another team could pick up, and we have had software running in production since 2018.

Typical engagements start at EUR 12,000 for a single-platform app and EUR 24,000 to 60,000 for an iOS and Android MVP with a backend. We work in Czech and English.
