in-depth: ZuckOff Is a Free App That Sees Meta Glasses Before They

A new, free mobile application called ZuckOff is empowering individuals to detect the presence of Meta's smart glasses in their immediate surroundings. Developed by 30-year-old Polish coder Pawel Szydlowski, the app leverages Bluetooth technology to identify various models of smart glasses, including Ray-Ban Meta, Oakley Meta, and Snap Spectacles. Since its August launch, ZuckOff has gained rapid traction, with over 5,000 downloads on Apple's App Store and 1,000 on the Google Play Store, signaling a growing public demand for privacy tools in response to concerns about unsolicited filming.

Meta's smart glasses have faced significant public scrutiny due to widespread reports of individuals being recorded without their consent. Incidents range from unpermitted filming in public spaces to more egregious cases, such as men using the devices to film dates, prompting many venues like schools and cinemas to issue outright bans. The controversy is exacerbated by the fact that the glasses' recording indicator lights can be easily circumvented with simple hardware modifications, enabling covert recording despite Meta's stated intention for the camera to be noticeable.

Szydlowski engineered ZuckOff by meticulously recording the unique Bluetooth signals emitted by various smart glass models. This process allowed him to create a digital "fingerprint" for each device, enabling the app to flag when a matching manufacturer identifier is detected nearby. While the app can indicate the rough proximity of smart glasses based on signal strength, it cannot confirm if a device is actively recording or identify the person wearing it. Nonetheless, it transforms an otherwise invisible threat into a partially discernible one.

The urgency for such a tool is underscored by alarming statistics and reports. A January BBC investigation revealed dozens of online accounts featuring women filmed in public by Meta glasses without their permission, with one video garnering over 1.3 million views and exposing a 21-year-old woman's face and phone number. The sheer volume of Meta smart glasses in circulation—approximately 7 million pairs sold in 2025—amplifies the potential for privacy infringements.

Meta has attempted to address these concerns, announcing in July 2026 that an upcoming software update would detect physically tampered recording LEDs, disabling the camera functionality. Meta CTO Andrew Bosworth emphasized the company's design philosophy for the camera to be conspicuous. However, this stance conflicts with a core commercial appeal of the product: its ability to blend in, looking less like a camera and more like conventional eyewear.

ZuckOff’s development arrives as legislators begin to grapple with the implications of pervasive wearable cameras. California and other jurisdictions are exploring laws to criminalize the disabling of recording lights or filming individuals without explicit consent. The app itself is designed to be legally robust, as it merely detects existing signals rather than interfering with device operations, making it challenging for Meta to challenge its availability.

For users seeking enhanced capabilities, a ZuckOff Pro version is available for $25. This premium offering includes features such as historical logging of detections, data export capabilities (CSV), a homescreen widget, and continuous background monitoring with alerts, even when the phone screen is off. The app represents a proactive, citizen-led response to the evolving challenges of digital privacy, offering a measure of control in an increasingly surveilled environment, even as comprehensive legislative solutions remain in development.

FAQ

Q: What is ZuckOff and how does it work?

A: ZuckOff is a free mobile app developed by Pawel Szydlowski that uses Bluetooth detection to identify the presence of smart glasses like Ray-Ban Meta, Oakley Meta, and Snap Spectacles in your vicinity. It works by recognizing the unique Bluetooth "fingerprints" of these devices.

Q: What are the main privacy concerns associated with Meta smart glasses?

A: Primary concerns include unsolicited filming of individuals in public and private settings, often without their consent. The recording indicator lights on these glasses can be easily disabled, making covert recording possible, which has led to bans in various venues and incidents of non-consensual video sharing online.

Q: Can ZuckOff tell me if I am actively being recorded by smart glasses?

A: No, ZuckOff can only detect the presence and approximate proximity of smart glasses. It cannot determine if a device is actively recording or identify the person wearing them. It serves as a tool to make an otherwise invisible privacy threat partially visible.
