I made an app.

Nearby Glasses is here to warn you when smart glasses are nearby.

I hope it's useful for someone.

The app is now open source (AGPL-3.0), the app is free and rather simple

It's also downloadable outside the Play Store. iOS port is in the making. F-Droid is an option, will have to look into that

@yjeanrenaud So simple but so effective :)

I've got a pair of Meta Quest 1 and a Meta Quest 3 in the house if you need fingerprinting from them to see if you can filter them out?

@naturepunk @yjeanrenaud I think if they can be picked out it’s a good thing, but theoretically they can load the same type of capture and recognition capabilities- so even though it should be obvious someone is using them, they could be disguised as something else if not worn by the user? Seems fine to keep detecting them.
