Flick, strike, or snap — and your Wear OS watch fires a hero-grade sound effect the instant you move. Hands free, eyes up, fully in character — and with Pro, the same gesture flashes your lights and fires your smoke in sync.
The flagship — CosNFX for Wear OS
A natural gesture fires the effect the instant you move — the watch reads your motion, so your hands stay empty and your eyes stay up. It calibrates to the way you actually move, and with Pro the same gesture flashes your lights and puffs your smoke in sync.
Low-latency sound fires straight from the watch the moment a gesture hits — your hands stay free, your eyes stay up, and you stay in character. A quick double-tap arms or disarms, hands-free.
One gesture can also drive your gear over Wi-Fi — HTTP for WLED strips, Philips Hue, Home Assistant (smart plugs for smoke machines and fans), and ESP32/Arduino builds, plus OSC and Art-Net for lighting consoles and show-control — so the whole effect lands together.
Calibrate each gesture to the way you actually throw it, and the watch aims its detector at your real movement. Reset to the defaults any time — and Pro lets you record entirely new signature moves.
Heroes, monsters, and mages — each with its own colour and sound kit, a dynamic energy field, and a cinematic backdrop. Swipe to switch, or build your own from scratch.
The watch opens a full control panel in any browser on your Wi-Fi — gestures, sound library, props, calibration — gated by a 6-digit PIN the watch shows you. Open it from your phone or a laptop, in the browser you already have.
Link two or more watches over Wi-Fi for versus play — strikes deal damage, and a held Raise blocks an incoming hit. Bring it to a cosplay face-off, a reenactment, a LARP, or just a backyard duel with friends.

Straight answers
CosNFX runs on any Wear OS watch — Galaxy, Pixel, and others — so a standard smartwatch is all it takes. Prefer a turnkey device? Join the waitlist for the standalone CosNFX watch, with the software pre-installed.
Yes — completely. All 30 identities, every sound effect, every visualization, every gesture, the HUD, and the phone control panel are free, all included. The one optional one-time $4.99 "Pro" purchase (no subscription) adds the power-user tools: recording your own custom gestures and finisher combos, your own audio/image uploads, firing real props over your Wi-Fi, multi-device play, and multiplayer Battle mode. Optional add-on packs — extra audio, visualization, and graphic packs, plus smart ring integration — will come as separate purchases later.
The watch is fully standalone — it fires sounds entirely on its own, with or without Wi-Fi. Bring in Wi-Fi when you want the phone as a louder second speaker, the browser control panel, prop triggers (lights/smoke), or Battle mode.
CosNFX is a Wear OS app, so it runs on Wear OS watches — Galaxy, Pixel, and more — rather than Apple Watch / watchOS. The control panel is just a web page, so any phone's browser (iPhone included) can configure it and act as a speaker; the watch itself is the Wear OS part.
The CosNFX app is the first product — it lands on Google Play July 15. A standalone CosNFX watch (with the software pre-installed) and LED kits are next: join the waitlist and browse the store — I'll have them up the moment they're ready.
Everything runs locally, on your own devices — your data stays with you. The phone control panel is protected by a 6-digit PIN shown on the watch, so only you can control it even on shared venue Wi-Fi. See the privacy policy for details.
