Nearby Glasses scans Bluetooth signals to detect devices like Meta Ray-Ban smart glasses, giving users a heads-up about potential wearable surveillance.
The rise of smart glasses with built-in cameras has triggered a new privacy dilemma: people may be recorded without realizing it.
A new Android app called Nearby Glasses aims to flip that dynamic by alerting users when smart glasses or similar wearable tech are detected nearby.
The app continuously scans for Bluetooth signals from devices made by companies such as Meta, Oakley, and Snap, which produce camera-equipped smart eyewear.
In short, if someone near you might be wearing recording glasses, your phone could notify you first.
How the Nearby Glasses App Works
The app listens for nearby Bluetooth identifiers broadcast by connected devices.
Each Bluetooth device includes a manufacturer identifier, a public code that reveals which company produced the hardware.
When Nearby Glasses detects identifiers tied to companies known for smart glasses, it triggers an alert.
Key mechanics include:
- Continuous Bluetooth scanning to detect nearby devices
- Alerts when identifiers from Meta or Snap hardware appear
- Ability for users to add custom identifiers for broader detection
Think of it like a radar for wearable tech. Instead of spotting airplanes, it flags devices that might be recording.
Why the App Was Built
Developer Yves Jeanrenaud created the app amid growing backlash against always-recording devices.
Critics argue these products collect data about nearby people who never gave consent.
Jeanrenaud told TechCrunch he was motivated by “the sheer scale and inhumane nature of the abuse these smart glasses are involved in.”
He pointed specifically to concerns around Meta’s Ray-Ban smart glasses, which have reportedly been used in contexts such as filming or harassment.
On the project page, Jeanrenaud calls smart glasses an “intolerable intrusion” that ignores consent.
Another concern involves face recognition features potentially becoming default capabilities in smart glasses.
Jeanrenaud described that possibility as “a huge floodgate” for privacy-invasive behavior.
Not Perfect: False Positives Are Possible
The system isn’t foolproof.
Because the app identifies device manufacturers, it can mistake other hardware from the same company for smart glasses.
For example:
- A Meta VR headset might trigger an alert
- The app cannot always differentiate device types
However, VR headsets are typically large and obvious, making them easier to identify visually.
Testing the App in the Real World
In testing, the app scanned nearby devices while walking around a city neighborhood.
The result: no alerts for smart glasses, suggesting none were detected nearby.
To test further, a Bluetooth identifier associated with Apple devices (0x004C) was added manually.
The phone immediately flooded with alerts—likely detecting multiple nearby Apple products.
That experiment confirmed the app’s Bluetooth detection system works as intended.
What’s Next for Nearby Glasses
Jeanrenaud says the app is still evolving.
Planned or requested developments include:
- Additional detection features
- Expanded identifier databases
- A possible iPhone version, depending on time and availability
Still, the developer admits technology alone won’t solve the underlying issue.
“This is a technical solution to a social problem,” Jeanrenaud said, describing the app as “a desperate act of resistance.”
Meta and Snap did not respond to requests for comment.
So the question remains: as wearable cameras blend into everyday fashion, will tools like Nearby Glasses become essential for digital self-defense?
TL;DR:
A new Android app called Nearby Glasses alerts users if nearby devices from companies like Meta or Snap are detected via Bluetooth, potentially indicating smart glasses with recording cameras. Built as a privacy tool, it scans manufacturer identifiers and notifies users, though false positives can occur.
AI Summary:
- Android app Nearby Glasses detects smart glasses via Bluetooth signals
- Alerts users when devices from Meta, Snap, or similar brands appear nearby
- Created amid rising concerns about wearable surveillance and consent
- May produce false positives when detecting other devices from the same manufacturer
- iPhone version may come later depending on development time
