You put trackers on your stuff. You lose your stuff. You find your stuff via your smartphone and app. Its nothing new, but Tile Tracker ($19) just made tracking your lost items a worthy business. Not only does it locate your belongings via bluetooth on any IOS device, but recruits other Tile user’s apps via social media, allowing them to search for your signal as well, expanding your search’s reach—-all while maintaining privacy of course. Available for preorder.
