I made an app.
https://play.google.com/store/apps/details?id=ch.pocketpc.nearbyglasses
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 new spyware dropped 😁

@fuchsi

Smart glasses could be described as spyware (recording images and audio without your knowlege or consent).

This app isn't spyware. It's using information that is already available to your phone (Bluetooth IDs that other devices are already sending out on their own accord) and merely making it easier for you to be aware of that information.

@yjeanrenaud

@lady_alys @yjeanrenaud oh, my bad. I guess I should have written anti-spyware then.

I thought it would be something essential for a spy to be aware of people with spy glasses. I believe Counter- intelligence is the word for that?

@fuchsi

Ah yes! That's the term for it. :)

@yjeanrenaud

@lady_alys @yjeanrenaud thanks for correcting me.

Apparently that wording was enough to insult and block me.

@fuchsi @lady_alys I took no offence. Honestly, I was not sure where this is heading towards, either. Sorry people called you out
