I recently stumbled on a clutch of Tile Bluetooth trackers in an airport departure lounge. I’d just disappeared down a Bluetooth LE devices security rabbit hole and was using the RamBLE app to discover what was about (who knew there were so many Samsung Smart TVs around?). I’ve been aware of the Tile and it’s companion app for a while. As they didn’t work with Android until recently, I had resisted purchase. With a imminent family holiday to a large European theme park with a child with a history of legging it; I purchased a pack of four Tiles for £50.
