Smart Glasses Detection Apps Help Protect Privacy in Public Spaces
“We can do something about that.”
Since February, developers have released and updated several apps designed to detect smart glasses, including Ray-Ban Meta glasses, Oakley Meta glasses, and Snap Spectacles.
“It’s not at all surprising that people are developing apps to combat Meta glasses and other devices capable of secret public recordings,” Quintin told Ars. Many people have a “strong aversion to being recorded without their consent, and rightfully so.” According to Quintin, nonconsensual recording remains “the biggest problem with these glasses.”
Smart glasses detection apps are not perfect. In the best-case scenario, an app can alert users when compatible glasses are nearby by detecting the Bluetooth signal used to pair the glasses with a smartphone. However, the technology cannot determine whether the glasses are actively recording.
App developers remind users never to assume that someone wearing smart glasses is filming them. They also advise against confrontation and warn that they are not responsible for false positives, misunderstandings, or inaccurate results. Detection may become less reliable when walls, furniture, or people block or weaken the Bluetooth signal.
Despite these limitations, many users do not consider smart glasses detection apps a deal breaker. They want an easy way to scan a room for nearby devices, provide feedback to developers, and support the continued development of privacy-focused technology.
One of the earliest options, Glasses Near Me, is available for $2.99 on both iOS and Android. The app has been downloaded more than 100,000 times from the Google Play Store and remains one of the most popular smart glasses detection apps. However, developer Yves Jeanrenaud warns on GitHub that he is “not a professional developer,” that Bluetooth Low Energy device detection “may not work as expected,” and that the app “may have false positives.”
Jeanrenaud said he kept his goals modest after seeing online content portraying smart glasses as “an unacceptable, intrusive, and horrifying technology that ignores consent.” “I hope this app is useful to someone,” he wrote on GitHub. He also cautioned that he does not want to promote tech solutionism or give users a false sense of security. Smart glasses detection is “still an imperfect approach,” he said, and likely “always will be.”
