White swans mate for life. Black socks, not so much. Throw several pairs in the washer and dryer, and you\u2019ll often find that your socks ditched their mates and hooked up with new partners.\n\tActually, you probably won\u2019t even notice the new couplings at all, much less care. One black sock pretty much looks like another, which is why I'm spotlighting\u00a0Blacksocks, a free iPhone app and the inaugural app in my new Totally Ridiculous and Unnecessary Apps Hall of Fame.\n\tSwiss company Blacksocks SA developed the app to help you precisely match the company\u2019s RFID-embedded socks with their natural mates. The Swiss are famous for their precision in watches; who knew they\u2019d translated their technical prowess into footwear?\u00a0\n\tHere\u2019s the Blacksocks concept: For $189, the company sends you 10 pairs of black calf-length socks. The hypoallergenic socks are made in Milan \u201cby a second-generation family of sock artisans\u201d from a blend of Peruvian Pima cotton, lycra and polyamide.\n\tEach 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.\n\tAfter 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\u2019s mate has been located.\n\tIn my opinion, if you spend $189 on this product, you'll also want to buy a device that will locate your common sense. If you have several pairs of black socks, all from the same maker, how difficult\u2014or important\u2014is it to match them exactly? Do you really need to know a sock\u2019s "history," which the app and Sock Sorter provides? Can\u2019t you tell when a black sock is looking a bit gray and washed out? Do you need an app to tell you?\n\tMaybe the next step is for the communications chip in your Nike+ running shoes to communicate with the chip in your socks, though I doubt any good could come from that. If you\u2019re not careful, your socks and shoes might blab on Facebook about how much your feet stink.\n\tHave you spotted a candidate for the Totally Ridiculous and Unnecessary Apps Hall of Fame?
