Interactive electronics

Objects that make the world react.

CosNFX builds expressive electronics for costumes, stages, and curious spaces — all designed by one maker. It starts with the gesture-driven CosNFX app, the living Earth of Planetaria, and the true Moon of Lunaria.

Flagship · the app

Build a power. Throw it from your wrist.

A Wear OS watch app that fires sound, on-screen effects, and real props from a flick of your wrist — and all of it is yours to build. Your sounds, your gestures, your combos, so every character in your closet gets its own show.

Made by CosNFX

Built here, by one maker.

Every product in this store is designed and built by the maker behind CosNFX — software, firmware, and hardware. Here's what's live today.

Coming soon

Planetaria

A desktop digital twin of Earth — the actual planet, live: the real day/night line, NASA satellite clouds, city lights after dark, live USGS earthquakes, the ISS overhead, the night sky above your location, plus time, weather, and NOAA tide cards on your schedule — on a round AMOLED display.

Coming soon

Lunaria

The actual Moon, tonight: tonight's true phase, the Moon's real monthly wobble (libration), earthshine on the dark limb, and its true size as it nears and recedes — every frame computed on the device. Set it to a night that matters and it keeps that Moon forever. No app, no account, works offline.
