ZuckOff Is a Free App That Detects Meta Smart Glasses Nearby

Polish developer Pawel Szydlowski built ZuckOff, a free Bluetooth scanner that uses digital fingerprints to spot Ray-Ban Meta, Oakley Meta, and Snap Spectacles nearby. It hit over 5,000 App Store downloads in its first month and 1,000 on Google Play. The app matches unique identifiers against manufacturer IDs but cannot tell if the glasses are recording or who is wearing them. Meta pushed an update in July that blocks recording when the LED is tampered with, though tape still defeats the light. Roughly seven million pairs of Meta smart glasses were sold in 2025. A BBC investigation found accounts posting non-consensual footage, including a woman's face and phone number, with one video exceeding 1.3 million views. The basic scan is free on iPhone; a Pro version adds background monitoring, widgets, alerts, history, and CSV export.
