Camera glasses announce themselves over Bluetooth. ZuckOff listens for those announcements and tells you when a lens is in the room. ■ What it spots • Ray-Ban Meta and Oakley Meta, by the manufacturer signature in their Bluetooth advertisement • Snap Spectacles • Display glasses and headsets, including Quest and Vision Pro, are named in the log but never flagged: a headset is a camera you can see coming • The full list, and how each one is recognised, is in the app ■ The evidence, shown • Every flag lists what matched, whether that was a manufacturer ID, a service UUID or an advertised name • Confidence is rated possible, likely or strong, and the app says which • You can disagree with it, because the reasoning is never hidden ■ Every device, logged • Sightings keeps a record of all Bluetooth devices heard nearby, glasses or not • A signal timeline for each device • Own a pair yourself? Mark them once and they stop raising alerts ■ On Apple Watch • Check around me scans from your wrist for fifteen seconds and shows the same evidence as the iPhone • Meeting mode, part of Pro, keeps scanning until you tap Stop and buzzes when a pair turns up • watchOS only lets the watch listen while ZuckOff is open on its screen. With Always On that includes time with your wrist down, and the Return to Clock setting can stretch it to an hour • With Pro, a watch face can show the last verdict from your iPhone ■ On your Mac • ZuckOff for Mac is on the Mac App Store, for macOS 15 or later. It listens from the menu bar or the Dock • Pro bought on your iPhone unlocks it on a Mac signed in with the same Apple Account ■ Shortcuts and Siri • Start scan, Stop scan, Get scan status and Get suspect count work in the Shortcuts app, in automations and with Siri • An automation can stop the scan when you get home, even with ZuckOff closed, and start it again when you leave • Starting a scan with ZuckOff closed needs Pro with background scanning on. Without Pro the action asks to open the app ■ How close, not which way • Signal strength gives a rough distance and no direction at all • ZuckOff shows proximity bands rather than an arrow, because an arrow would be invented ■ What it cannot do • Glasses advertise loudest while powering on, pairing, or leaving the case. Once paired to their owner's phone they can go quiet, so silence here does not mean nobody is recording • A detection does not mean anyone is recording either. ZuckOff sees that a device is nearby and nothing about what its owner is doing with it ■ Your data stays on your phone • No account, no analytics • The log never leaves unless you export it yourself, or choose to send a hardware report for a device ZuckOff does not recognise, so new glasses can be added later • A report shows you exactly what it contains before anything is sent • Your iPhone shares its last verdict with your paired Apple Watch and nothing else ■ ZuckOff Pro Scanning is free and always will be. Pro is for the times you are not looking at the screen: background monitoring, alerts, the Live Activity, the Home Screen widget, meeting mode and the watch face on Apple Watch, sighting history beyond 24 hours, and CSV export. $9.99 per year, with the first week free. The subscription renews automatically unless it is cancelled at least 24 hours before the period ends, and renewals are managed in Settings on your device. A lifetime option is also available: one payment, no subscription, Family Sharing on. One purchase covers iPhone, Apple Watch and Mac. ZuckOff is an independent app and is not affiliated with, endorsed by or connected to Meta Platforms, Luxottica, Ray-Ban, Oakley or Snap.

ZuckOff's advantage is update cadence (every 3 days vs every 11 days). On price, ads and device support there is nothing between them.
