A cottage industry of smartphone apps has sprung up to detect Meta AI glasses in the wild, with Nearby Glasses passing 100,000 Play Store downloads at $2.99 and a newer free app called Zuckoff climbing iPhone charts in early August 2026. The tools scan for the Bluetooth signals that Ray-Ban Meta, Oakley Meta, and Snap Spectacles emit when paired with a phone, giving bystanders a rough way to tell when a recording device may be nearby. They arrive as public bans on the glasses spread from schools and courts to entertainment venues and, most notably, DEF CON 2026, which prohibited smart glasses with no exceptions.
Meta dominates the category, and the volume of secret-recording content circulating on social media has driven the backlash. The Electronic Frontier Foundation has flagged the glasses' small recording LED — which can be covered with a sticker — as the only meaningful bystander safeguard Meta ships. EFF staff technologist Cooper Quintin told Ars Technica the LED is "better than nothing, but not by much." The Financial Times reported last month that Meta is testing a "super sensing" prototype that would capture a wearer's every moment, and that executives are planning not to activate the LED when those features are running.
The trust problem got worse in June, when Wired and EFF revealed that Meta had quietly installed an unreleased facial-recognition system on 50 million phones through its smart-glasses app. Meta pulled the system after the reporting, but it has not said whether or when it might try again. The company did not respond to a request for comment on the detector apps or its facial-recognition plans.
“It is completely unsurprising that people are building apps to fight back against Meta glasses and other surreptitious public recording.”— Cooper Quintin, EFF staff technologist
Key facts
- 01Nearby Glasses, priced at $2.99 on iOS and Android, has topped 100,000 downloads on the Play Store since February 2026.
- 02Zuckoff launched free on iPhone in early August 2026, with a $10-per-year perpetual scanning subscription and 12 Android testers being recruited.
- 03Meta quietly installed an unreleased facial-recognition system on 50 million phones in June before deleting it after Wired and EFF exposed it.
- 04DEF CON 2026 banned smart glasses outright, joining schools, courts, restaurants, and entertainment venues that have restricted the devices.
- 05Antizuck Smart Glasses Scanner reached near the top of iPhone charts in July 2026 at $3.
The detector apps themselves are the work of solo developers, not established security vendors. Nearby Glasses was released in February 2026 by Yves Jeanrenaud, who describes himself on GitHub as "no pro developer" and warns that "detecting Bluetooth LE devices might sometimes just not work as expected, and false positives are likely." He wrote that he built the app after seeing content that framed smart glasses as "an intolerable intrusion," but added that he does not "want to promote techsolutionism, nor do I want people to feel falsely secure."
By July, a second app, Antizuck Smart Glasses Scanner, was nearing the top of the iPhone charts at the same $3 price point. A high school teacher review called it the "best $3 I've spent," citing concerns that students could record classrooms with AI glasses. The apps share a common design: alert the user when a known Meta or Snap glasses Bluetooth identifier appears within range, log nothing, and disclaim any liability for false positives or confrontations.
Zuckoff, the most recent entrant, launched free on iPhone in early August 2026 and is recruiting 12 testers for an Android release later this year. Perpetual background scanning costs roughly $10 per year, which creator Pawel Szydlowski told Ars covers ongoing support. Szydlowski said he built the app in a week, drawing on 10 years of iPhone development experience and an earlier project that scanned for nearby Bluetooth devices.
The hardest part, Szydlowski said, was assembling a comprehensive list of the manufacturer identifiers that Ray-Ban Meta, Oakley Meta, and Snap Spectacles broadcast, so the app can filter out benign Bluetooth traffic like headphones and watches. He crawled Instagram and Reddit posts from owners to build the database, and users have been submitting new identifiers through app feedback. Thousands have downloaded Zuckoff since launch, with feature requests already pushing improvements to background alerting.
“I was like, 'I can do something about it, so let's go.'”— Pawel Szydlowski, Creator of Zuckoff
The apps have real limits. They can detect that a paired pair of Meta glasses is powered on and within Bluetooth range, but they cannot tell whether the glasses are actively recording. Walls, bodies, and other obstacles can block the signal entirely. Every developer in the category tells users not to confront wearers on the basis of an alert. Quintin's framing is that the apps supplement social norms and venue bans rather than replace them: "You need to have the social construct around these being unwelcome, and you also need to be able to find when people are using these."
Quintin also warned that the current threat model — creepy recordings uploaded to social media, plus documented use in immigration raids and harassment of sex workers and retail staff — could get worse if Meta ships facial recognition on the glasses themselves. That would let wearers identify strangers in real time and, combined with generative video, create convincing deepfakes or nonconsensual intimate imagery of people who never knew they were filmed. EFF is pressing lawmakers to grant a private right of action for biometric-privacy violations, arguing that without one, competitive pressure will push every smart-glasses maker toward the same feature set.
The detector-app boom is a market signal Meta cannot easily dismiss. Ray-Ban Meta is the best-selling product in a category Meta is betting on to define the post-smartphone interface, and a growing share of the buying public is now installing tools designed to flag Meta hardware as hostile. That is a different problem from bad press: it is a durable second-order market forming around the assumption that Meta's own privacy controls are inadequate. If the super-sensing prototype ships with the LED disabled, the detector apps become the only signal bystanders have — and their developers, none of whom work for Meta, will effectively be setting the terms of consent for a product Meta is trying to sell into every restaurant, classroom, and courtroom in the country.
