CosNFX
Trigger sound effects as you move.
Flick your wrist for a sword swing or lift your arm for a thunderclap. CosNFX plays sounds and animations as you move. Pick from 30 free characters, or use Pro to perform with your own sounds, artwork and gestures.
Requires a compatible Wear OS watch. The Android companion is optional.
From wrist flick to sound
Pick a character
Try a Superhero, Pirate, Cryomancer or another profile. Each comes with its own sounds, artwork and animations.
Turn gestures on
Tap the center of the watch screen. Tap again to pause gestures between scenes.
Make a move
Flick, strike, clench or raise your arm to play its assigned effect. The watch can play on its own, offline.
Use the Android companion to edit a profile on a larger screen, or open Mission Control in a browser on the same Wi‑Fi network. You can also send sound to the phone or browser.

Set up effects on your phone
Start with a button on the watch image. Then choose the sounds, visuals and devices that respond to that move.
Choose a button
Tap a number on the watch image to open the effect settings for that button and its gesture.
Route sound to three speakers
In this upcoming Pro preview, one Pirate gesture can play three sound layers.
- Main → Phone
- A cutlass swing from the louder phone speaker.
- Support → Watch
- A hilt click right where you move your wrist.
- Environmental → Browser
- A creak of the ship’s deck from a linked computer across the room.
Choose the output, volume and delay for each layer. Leave the extra layers off when you only want the main sound.
Pair the sound with a visual
Pick the animation that plays with a move. With Pro, use your own artwork to give the watch a look that fits your costume.
Send a cue to a light
In Pro, one gesture can play a sound, flash the phone and send a command to a networked light or prop. Add another device action when the same move should control more than one prop.
Decide what starts a cue
In the upcoming Pro update, a spoken phrase can start an entrance and a location cue can run an effect when you enter a marked area. You can also set a gesture or launch a cue by hand.
Line up your entrance
Start the soundtrack, animate the watch, then change the lights. Set when each action runs and rehearse the sequence from the phone.
