Wrist Relay Turns the Apple Watch Into a Tiny Walkie-Talkie

Field notes

The documented interaction uses invitations rather than public rooms: a recipient receives a notification, joins or declines, and both Watches enter a temporary conversation. The main control is deliberately reduced to hold-to-speak and release-to-listen, with haptic feedback and one-speaker-at-a-time audio. The project reports that a physical Watch has already connected through a Cloudflare-backed relay, while remote playback, latency, sleep, and reconnect behavior remain under test.
