New, Hopefully Better Bluetooth Item Locator Device | Tile Mate 2018

How it works is you get these little devices called Tiles.  Activate it via bluetooth on your device and account.  Now if it is in bluetooth range, you can activate the locator sound, and the app also tracks its last approximate GPS location when it connects with your phone.  

We used to have similar devices in the 90s when nobody was using smartphones, but with no tracking.

The most useful feature when your devices are out of bluetooth range is the Community.  The Tile community is huge (supposedly).  So if an item is noted missing, other Tile users that happen to be in bluetooth range will ping the location back to you (anonymously).  Genius!
