Helium 4 is a solo indie studio focused on on-device AI, mobile engineering, and privacy-first utilities. Everything ships offline-ready, fast, and without compromise.
Helium 4 is built by a single developer with 5+ years of mobile and full-stack experience across Android, iOS, React Native, Flutter, and web.
The focus is on shipping products that solve real problems — especially at the intersection of AI and mobile, where most solutions still require cloud connectivity and sacrifice privacy.
Every project at Helium 4 is built to run fully offline, perform well on mid-range hardware, and respect the user's data.
A fully offline AI companion app powered by llama.cpp running directly on Android hardware. Lucy supports six distinct personalities, persistent memory across sessions, LAN AI sharing, and smart model management — all without ever connecting to the internet.
Screen sharing between mobile devices over local Wi-Fi — no internet required, no accounts, completely free. ZeroLink casts one phone's screen to another in real time using direct LAN connections, with zero data leaving your network.
