White swans mate for life. Black socks, not so much. Throw several pairs in the washer and dryer, and you'll often find that your socks ditched their mates and hooked up with new partners.
Actually, you probably won't even notice the new couplings at all, much less care. One black sock pretty much looks like another, which is why I'm spotlighting Blacksocks, a free iPhone app and the inaugural app in my new Totally Ridiculous and Unnecessary Apps Hall of Fame.
Swiss company Blacksocks SA developed the app to help you precisely match the company's RFID-embedded socks with their natural mates. The Swiss are famous for their precision in watches; who knew they'd translated their technical prowess into footwear?
Here's the Blacksocks concept: For $189, the company sends you 10 pairs of black calf-length socks. The hypoallergenic socks are made in Milan "by a second-generation family of sock artisans" from a blend of Peruvian Pima cotton, lycra and polyamide.
Each sock has an embedded RFID tag. Along with the socks, you get a wireless "Sock Sorter," a handheld RFID reader that communicates with the Blacksocks app on your iPhone (3GS or newer). Upon receiving your smart socks, you pair them using the app and the Sock Sorter so the iPhone app knows which socks belong together.
After doing laundry you just hold the Sock Sorter over the RFID chip on a particular sock; scan the device over all the socks in your basket; and the iPhone makes a sound to indicate when the sock's mate has been located.
