The free app ZuckOff, developed by Polish tech whiz Pawel Szydlowski, alerts users to the presence of smart glasses in their vicinity via Bluetooth detection. Since its launch in August, it has caught the attention of over 6,000 users, including those concerned about the privacy implications of Meta’s smart glasses.

Meta’s smart glasses have faced scrutiny for their ability to secretly film users, with one BBC investigation highlighting instances where women were filmed in public without their consent. The recording indicators on these glasses can be easily circumvented, leaving users vulnerable. Roughly 7 million pairs were sold in 2025, making the issue of privacy a widespread concern.

ZuckOff works by recording Bluetooth signals from various smart glasses models, such as Ray-Ban Meta, Oakley Meta, and Snap Spectacles. While it can’t pinpoint exactly who is wearing the glasses, it does offer proximity information, turning an invisible threat into a partially visible one. This could be a valuable tool until more robust legal protections are put in place, as seen in California’s recent laws against disabling recording lights or filming without consent.

The app’s Pro version, priced at $25, offers additional features like history logging and continuous background monitoring. However, it remains a legal grey area, as it doesn’t interfere with the glasses’ signals. Until then, ZuckOff might just be your best bet to stay one step ahead in this tech surveillance age.
