Constantly misplacing… just about everything? Then check out Tile. These compact, pure-white gizmos work with Bluetooth 4.0-equipped iOS devices to keep tabs on your stuff within range (between 50 and 150 feet), but stand out from the pack of thing-finders in that other users can aid in relaying location information of your Tiles, should they happen to be nearby. Tiles are inexpensive, waterproof, easy to set up, include a set of double-sided adhesive, and sport built-in speakers to help you find your gear. Only downside: they last precisely one year before requiring recycling, since batteries are not user replaceable or rechargeable.
