Will the beacon pulse be visible to other people at the bar?

In discreet mode only 4 of 32 columns light at low brightness on the wrist edge, so anyone across the room sees a dark sleeve while you still catch the amber glow from your own periphery.

Does the collider need my wingman to also own a sleeve?

No. The profile listens for any BLE advertising beacon, so your friend's phone with a beacon app can drive the signal and your sleeve displays it.

How do I re-pair the beacon for a different friend tomorrow night?

Hold Pad 1 again, or edit the beacon UUID in the Sleeve Studio app and send the updated profile over Bluetooth in under 10 seconds.

Hot/Cold Wingman Beacon on a Wearable 8×32 LED & Touch Sleeve

When your wingman signals from across a loud room, a discreet 4-column edge pulse on the 8×32 RGB LED matrix slides from cool blue to warm amber so you read the cue on your outer forearm — no phone, no words ($199).

A private signal only you decode: A 4-column edge pulse slides from blue (not yet) to amber (now) in your own peripheral vision.
Phone stays pocketed: No glare of checking a text mid-conversation — the cue is invisible to everyone but you.
Ships as 1 of 50 modes: Pre-loaded as Edge Beacon Discreet; pair a friend’s beacon in the Sleeve Studio app.

Why You Can't Text Your Wingman Across a Crowded Room

Phone checks read as rude: Pulling out a phone mid-conversation signals disinterest to the person standing in front of you.
Peer-to-peer over Bluetooth: A friend’s sleeve or phone beacon nudges your wrist edge — no cell signal required.
Peer-reviewed textile roots, shipping hardware: The Oct 2026 NUS Nature paper coined “garment GUI” with a lab-only woven pixel fibre (not for sale); our shipping $199 sleeve uses 5 sewn conductive-fabric pads and a removable 8×32 LED pod.
