Ever wanted to give yourself a “real-world search bar” to easily find misplaced items, like keys and TV remotes? Now you can, with location sensors that attach to your stuff as key fobs or stick-on tags.
These simple devices use short-range signals like Bluetooth to digitally tether critical items to your smartphone. You’ll get an instant alert if you start to leave something behind, and a mobile app will guide you back toward the wayward object. Many devices can chirp, beep, bleat or otherwise make noise to reveal their location, and some even feature GPS and an independent cellular data connection to report their location from just about anywhere on Earth.
