New app scans Bluetooth to warn if smart glasses are nearby
Feb 24th 2026
A hobbyist-built app detects distinctive Bluetooth signals from smart glasses, such as Meta Ray-Ban, and sends push alerts to warn users about potential covert recording as companies add AI features to wearables.
- The app scans local Bluetooth signatures and alerts users when it detects a device that matches known smart glasses models.
- It was developed by a hobbyist and is not officially supported, so its accuracy and security have not been independently verified.
- Bluetooth detection can fail if glasses do not broadcast, have Bluetooth turned off, or use proprietary protocols, and it may produce false positives.
- Meta has been reported to be developing a facial recognition feature called Name Tag for its smart glasses, increasing privacy concerns.
- Stalkers and harassers have previously used smart glasses like Meta Ray-Ban to record people without their knowledge or consent, which motivated the app.
