Four smart glasses detector apps launched or updated in four days, and none detects recording

Four iPhone apps for spotting nearby smart glasses launched or updated between September 28 and October 1, according to MIXED's report. None can tell whether a camera is recording. Spex and Smart Glass Finder explicitly acknowledge that limit in their listings.

That extends the distinction in our earlier Bluetooth scanner story. Detecting glasses leaves their camera activity unknown.

What changed

Spectre reached version 2.5 on September 28. Its update improves recognition of Ray-Ban Meta and Oakley Meta frames and avoids duplicate detections when glasses rotate their Bluetooth address. Spex and Smart Glass Finder debuted that day. AntiZuck reached version 1.1.0 on October 1.

The apps passively scan Bluetooth broadcasts. Spex warns that connected, idle glasses broadcast rarely. AntiZuck says broadcasts mostly occur at power-on, pairing and case-open. Silence can therefore hide nearby glasses.

Spectre's artwork says "Know when you're recorded", despite that gap. MIXED reports no independent test of the four apps.

What to compare before paying

MIXED reported these US prices and iOS requirements. It checked Spectre and Spex prices on October 3.

Paid extras include background alerts, longer history and lists that exclude your own glasses. They extend monitoring rather than reveal recording.
