We’ve seen a few Kickstarter-birthed Bluetooth “smart tags,” pop up in the last few years, which means it’s about time for Chinese companies to start mass producing them for absurdly low prices.
Aukey’s Nut attaches to your keyring, backpack, dog, or just about any other easily-misplaced item, and can emit an audible alarm when invoked by a Bluetooth-connected smartphone app. And on the flipside, if you have a Nut handy, but can’t find your phone, the alarm works in reverse: Just hit the button on your Nut, and your phone will beep as long as it’s in range.
Many of these trackers include a single-use battery, and are meant to be thrown away once they die. The Nut though uses a standard, inexpensive watch battery that lasts for up to three months, and that you can replace on your own.
