Developers launch Bluetooth detector apps to alert users to nearby smart glasses
Tools like Zuckoff scan local Bluetooth signals to estimate the proximity of smart eyewear, though they cannot confirm if active recording is taking place.
The short version
- Developers are releasing mobile apps, including Zuckoff, Antizuck Smart Glasses Scanner, and Nearby Glasses, to detect nearby smart glasses like Ray-Ban Meta devices via Bluetooth signals.
- The apps estimate proximity using hardware signatures and vendor IDs, helping address growing privacy concerns over discreet video recording and AI data collection.
- Hardware limitations mean detector apps cannot tell whether a device is actively recording, and custom hardware modifications can disable recording indicator lights.
- App developers and tech experts suggest long-term privacy solutions may rely on clearer social norms, built-in operating system detection, or camera-free smart glasses design.
Key facts
- Software developers have launched apps such as Zuckoff, Antizuck Smart Glasses Scanner, and Nearby Glasses to identify nearby smart glasses by sweeping local Bluetooth frequencies.[CNET]
- The free iOS app Zuckoff, created by Pawel Szydlowski, has recorded 2,000 sign-ups since launching in early August 2026, with an Android version in development.[CNET]
- Smart glasses detection apps identify device signatures and approximate signal strength, but they cannot determine direction or confirm if a device is actively recording.[CNET]
- Some users and hardware modifiers disable or bypass capture LED indicator lights to record secretly with smart glasses.[CNET]
- Some hardware manufacturers, such as Even Realities with its G2 model, are releasing camera-free smart glasses to address privacy concerns.[CNET]
What remains uncertain
- It is unknown whether major tech companies will alter hardware or software protocols to evade Bluetooth detection by third-party apps.[CNET]
- Because paired devices can stop broadcasting strong Bluetooth signals, silence detected by an app is not definitive proof that no nearby recording is occurring.[CNET]
