This app alerts you if someone is secretly recording you
Worried someone might be wearing smart glasses and recording without you knowing?
Nearby Glasses is a free Android app that alerts you if smart glasses from Meta, Snap, or Luxottica are within Bluetooth range.
Created by sociology professor Yves Jeanrenaud in Germany, the app was built out of concern for privacy and unwanted filming.
How does the app work?
The app scans for Bluetooth signals unique to certain smart glasses, with a detection range of about 10-15 meters outdoors and 3-10 meters indoors.
You can tweak its settings to scan wider or add custom devices.
Heads up: it sometimes picks up other gadgets like Meta VR headsets by mistake, and only sends local notifications—no exact locations or identities.
As Jeanrenaud puts it, the app is "very imperfect," but he hopes it helps people feel a bit more aware.
