A 30-year-old Polish software developer has built an iPhone app that detects Meta smart glasses in the vicinity and estimates how far away they are by reading the Bluetooth signals the glasses broadcast. It has around 5,000 users a month after launch.
Pawel Szydlowski bought several models of smart glasses and catalogued their Bluetooth fingerprints, then wrote software that matches what a phone hears against that catalogue.
“If the unique identifier matches, and also if the manufacturer identifier matches, then we have like an ultimate combo there,” he told Business Insider.
The app is free, with a paid tier that sends notifications in the background. His argument for building it is one sentence long.
“We as a society have the right to at least know that someone is recording,” he said.
