ZuckOff turns camera glasses' own Bluetooth chatter into a proximity alarm

Smart glasses like Ray-Ban Meta, Oakley Meta and Snap Spectacles broadcast identifiable Bluetooth signals, and ZuckOff, an independent iPhone app, listens for those manufacturer signatures to warn you when a recording-capable pair is nearby. Everything runs locally — no account, no data leaving the device — and each alert comes with the underlying evidence so you can judge it yourself. The app logs every Bluetooth device it hears, lets owners whitelist their own glasses, and surfaces alerts through background notifications, a Home Screen widget, a Lock Screen Live Activity, and Shortcuts/Siri automation, with full CSV export.

The developers are candid about the limits. Glasses are loudest when powering on, pairing or leaving their case, and most keep advertising while worn, but a few standalone models stay silent — so quiet is not proof nobody is recording, just as a detection is not proof anyone is. Signal strength offers a rough distance estimate and no direction. Detection rules are built from packet captures of real hardware, and because the team owns only a handful of pairs, they’re soliciting scan captures and loaner devices from users to broaden coverage, and are open to collaborating with privacy groups.

The project reflects a growing countersurveillance response to always-on wearable cameras: rather than relying on visible recording indicators, it weaponizes the devices’ own wireless emissions against them. It’s funded through merch and small donations, and is explicitly unaffiliated with Meta, Luxottica, Ray-Ban, Oakley or Snap.
