Using Bluetooth you can track down the Tile keyring within a 200ft range.
It's a neat idea, well-executed and it seems there's a crowd of people who would agree.
Logging into the smartphone app, I can see 2895 equally forgetful users are within the vicinity. Which is just as well — as part of what makes it such a useful bit of tech is the ability to crowd-source help from other Tile users.
Somewhat melodramatically, you have the ability to "set up a search party". Within seconds you can have half of Christchurch searching on your behalf for your misplaced camera bag. Or, at least anyone with the app and a good signal for their handset.
Having got over the embarrassment of advertising my inability to keep track of my belongings to thousands of strangers, I was quickly updated by the app:
"Your camera's location was found by the community, say thanks!"
