Independent app studio from Kraków, Poland.
We build software that does less — intentionally. Minimal design. Thoughtful features. No noise.
We build iOS apps for mental health and self-reflection, and publish open-source React Native packages. Everything runs locally on your device — no cloud sync, no accounts, no tracking. Your journal is yours alone. We think good tools should be quiet: present when needed, invisible when not.
We extract reusable patterns from our apps and publish them as open-source packages under the @byarcadia-app npm scope. Greek mythology naming — Aether for the UI layer, Plutus for payments. Battle-tested in production, designed to save other developers the same boilerplate.
Dominik Woźniak — frontend and mobile developer based in Kraków. Building with React Native, Expo, and TypeScript. Writes about development on Medium.
