The next watch and phone update is being revised before publication. The previously submitted 2.18.0 is being held; the final release details will appear here once they are confirmed.

• More scene, less clutter. Updated backgrounds fill the watch screen. Profile names and gesture numbers appear briefly, while a soft center indicator replaces the old arm button. Tap a gesture area for its number and instruction; hold it to turn that gesture on or off.
• Controls a swipe away. Mission Control holds the address and PIN. Sound chooses Watch, Phone and Web playback. Visuals controls the background, effects, rotation and indicator style. Your saved choices carry forward.
• Companion connection improvements. Profile synchronization and interrupted sound connections have received further fixes to help the phone and watch recover their shared setup.

The original 30 profiles, their current kits, the included library, all seven built-in gestures and combos remain free. Pro remains a separate one-time purchase. Paid profile packs are separate from Pro; Sports and Arcade Night are in development.

New character effects, Superhero sounds, and smoother gestures

Watch 2.15.3 and phone companion 1.2.1 are available on Google Play. This October release brings new character effects and Superhero sounds, more comfortable gestures, and independent controls for your watch's background and animation.

• Thirteen new fullscreen watch effects. Choose from 38 effects, including Primal surge, Devouring maw and Pirate's Rogue wave. Mercenary now starts with Hero Impact. Werewolf and both cats keep Claw scratch; Storm God and Picochew share Voltaic. Your saved selections are preserved.
• A new seven-sound Superhero kit. The replacement kit covers both wrist rotations, Down-punch, Strike, Fist clench, Raise and Fist pump. Your custom sound assignments and uploads stay in place.
• More comfortable gestures. Wrist rotations recover sooner, Strike accepts a compact forward punch, and Raise uses a 200 ms upright hold. Lower your arm before the next Raise; wrist orientation can also trigger it during an elbow bend below head height. Fist pump recognizes a downward pull toward your body.
• Deliberate arming. Tap the identity name to arm or disarm. A forceful wrist flick no longer disarms the app.
• Saved identities and playback fixes. Delayed Mission Control refreshes preserve newer edits; stale saves are rejected with the local draft retained. Sound playback keeps its selected clip when settings change, and reconnection, visual reset and purchase-recovery fixes address interrupted sessions.
• More control over your watch display. Keep an uploaded image without the built-in HUD backdrop, or choose a black background while retaining your image selection. Button effects and wrist-driven visualization rotation now have independent on/off controls. Creature uses Devouring Maw by default; existing saved choices are preserved.
• Matching visuals on the phone. The companion's VFX Stage uses the profile's selected visualization and follows the profile that triggered a gesture. Mission Control also follows identity changes made on the watch while protecting unsaved edits.

All 30 built-in identities and the included sound and visual library remain free. The optional one-time Pro unlock still adds uploads, custom gestures, prop control, extra Mission Control screens and Battle mode. A Wear OS watch is required; the phone app is its companion. Gesture response depends on watch placement and movement, so rehearse your own setup.

Phone checkout, clearer controls, and smoother effects

Watch 2.15.1 (230) and phone companion 1.2.0 (15) were published on September 3, 2026. This release brings the August fixes and checkout improvements into the published app.

• Finish Pro checkout in the phone app. Tap Unlock Pro on the watch and an updated companion opens to the upgrade screen. If it does not open, start CosNFX on the phone and tap Unlock Pro in System. One purchase covers watch and phone installed under the same Google account.
• Clearer first use. A first-fire hint appears on the watch, all seven gestures start enabled on a fresh install, and idle auto-disarm gives a double buzz and a visible notice.
• Effects adapt to the watch. The visualization engine adjusts detail to rendering load, and the pad that fired pulses so you can see which gesture registered.
• Better prop feedback. Failed prop actions surface in diagnostics and a wrist cue; Art-Net actions preserve the other channels in the universe.
• The Pro boundary is clearer. Ordinary watch, phone, and browser audio routing is free. Pro adds extra simultaneous Mission Control screens, alongside uploads, custom gesture recording, props, and Battle mode. Built-in calibration remains free for Underhand, Overhand, Down-punch, and Strike.

Gesture tuning has been measured on Galaxy Watch 7. On another compatible watch, set the correct wrist, calibrate the four supported directional gestures, and rehearse your setup.

The big one: a new look, a new library, and every fix

Three updates that were queued separately ended up shipping together, so this release changes how CosNFX looks, what it sounds like, and how it behaves on day one. Everything you have set up carries over.

• Your buttons take the shape of your character. On the watch ring, each of the seven pads is drawn in the silhouette of the identity wearing it — a shield, a claw, a crescent, a bolt — so the ring tells you who you are before you read a word. The numbers 1–7 stay exactly where they were.
• Mission Control is rebuilt around the Stage. Your buttons appear as a live ring in the browser: tap a pad to set its gesture, sound, and effect; the pads flash as you perform; tap the centre to arm. Four zones — Stage, Show, Library, System — hold everything else, in place of the old row of tabs.
• Finding a sound is finally quick. A searchable browser with kit filters replaces the long dropdowns, and Test on watch plays the sound through the watch speaker before you commit to it — so you hear it where it will actually fire.
• The phone companion reaches 1.0. Same four zones, same shaped-pad ring, and it flashes live as you perform. It also draws far more efficiently than before, which is easier on your battery.
• A free Halloween pack: three cinematic kits. Haunted Manor (dragging chains, a door that opens by itself, a midnight bell), Banshee (an all-vocal ghost — whisper-screams, guttural moans, a full banshee wail), and Witching Hour (bone snaps, a raven that answers your beckon, a full-moon wolf howl, a real witch's sneer). Built from licensed cinematic recordings plus a few designed sounds, covering all seven gesture roles — free for everyone, in time for haunt season.
• A leaner library. The early placeholder sounds from the beta era retire (about 140 files), which makes the app a noticeably smaller download. Every one of the 210 curated kit sounds stays.
• Your setup is protected. The update remaps profiles automatically. If a gesture was pointing at a retiring sound, it falls back to that identity's default kit sound — open Mission Control or the phone app and pick a new one whenever you like. Anything you uploaded yourself stays exactly where you put it, along with your custom gestures, combos, and calibrations.
• Your sound kits play from the very first gesture. Fresh installs used to spend their first session on placeholder tones while the real library finished loading. Now the kits land the moment they're ready.
• Strike and Raise are on out of the box, and both read the same on either wrist, so a brand-new install has working gestures before any setup.
• Clearer Pro messages. When a Pro feature is locked, the app says so — and points you at the phone app, where one purchase covers watch and phone on the same Google account.
• Pairing works in every language. The Mission Control PIN always displays digits your browser keypad can type, whatever language your watch is set to.
• Sound survives Bluetooth shuffles. If the audio route changes mid-session, the engine rebuilds itself instead of going quiet. A reconnect loop that could nibble battery when a second device tried to link is gone, along with a stack of smaller hardening under the hood.

CosNFX is live on Google Play

Launch day. Free, worldwide, on your wrist.

• All 30 identities and all 210 sounds, free. Heroes, monsters, and mages — each with its own kit, colors, reactive effect, and cinematic backdrop.
• One optional Pro unlock ($4.99, once) adds your own sound and art uploads, custom gesture recording, real light and prop control, multi-device playback, and Battle mode.
• The watch tile: swipe to CosNFX and one tap opens it armed — firing a second after you raise your wrist.

Ready for the world

The release-candidate sweep before production.

• Your gesture ring remembers itself. Ring button choices now persist across every launch.
• A claw-scratch effect joins the visual library — built for the Cat identities, available to any of them.
• First-launch loading got a hard pass, recalibration flows were unstuck, and the browser panel took its proper name: Mission Control.

The phone becomes a controller

The companion app grew from a remote into a full second surface.

• An on-screen gesture pad — play every effect from the phone, no watch required.
• Second speaker: the phone carries the sound over Bluetooth, so a pocketed phone throws the audio a hall can hear — Wi-Fi off.
• Camera-flash muzzle: the phone's flash fires on the beat of a gesture.
• Every editor — sounds, looks, gestures, calibration, combos — rebuilt native on the phone, in sync with the watch and Mission Control.

The sound library era

Three weeks of pure audio work — recording, curating, and cutting until every identity earned its kit.

• 210 curated sounds, role-matched per identity: Overhand carries the main attack, Underhand the second, Strike the melee, Down-punch the heavy impact, Fist the special move, Raise the charge-up, Hip thrust the emote.
• Every sample loudness-tuned for the watch speaker — measured on the hardware, kept only if it survived it.
• The Library got themed sections, live filtering, and grouped per-gesture pickers on every surface.

The HUD rework

The watch face became the costume piece it should have been all along.

• The numbered gesture ring — a glanceable ring of your armed moves, edge-glowing in your identity's color.
• Two backdrops per identity: a cinematic Scene and a single iconic Emblem — thirty new emblem artworks in one drop.
• Reactive visual effects went native per identity, and the engine learned to guard your battery: it idles honestly when disarmed and stands down after 15 idle minutes armed.

Where it started

CosNFX entered closed beta on June 30 with the bones it still stands on.

• Seven pre-calibrated gestures with per-wrist calibration, custom gesture recording, and timed combos.
• Real prop control over Wi-Fi — WLED strips, Philips Hue, Home Assistant relays — plus DMX over Art-Net and OSC for show-control rigs.
• Mission Control: the watch serves its own control panel to any browser on your network, locked behind a 6-digit PIN.
• Battle mode: linked watches, strikes that land damage, a held Raise that blocks.
