Anyone used/tried the 'Nearby Glasses' app on Android? Is supposed to alert you to nearby smart glasses that might be filming you without your knowledge. Uses Bluetooth LE to identify manufacturers ID from nearby devices Not something I have really thought about before but then got me wondering about what might be going on at the gym I attend. Am rural enough that it had not been much of a concern but rumour has it the things are becoming more common Definitely something to try next time I go to London https://play.google.com/store/apps/details?id=ch.pocketpc.nearbyglasses&hl=en-US
