Actually, it's designed to tell the user whether or not he/she stinks, not whether others stink. Turns out we don't need much help telling whether someone else stinks. It's our own odors we don't always smell.
So along came this Japanese company with a device that will detect odors and send a message to your phone. See This Japanese Device Will Tell You When You Stink:
The device conveniently fits in a coat pocket and detects specific chemicals associated with body odors. The two chemicals associated with the kind of smell that comes from a sweaty locker room are ammonia and isovaleric acid. 2-nonenal is linked to the smell that comes with old age and diacetyl makes you smell like ‘rancid cooking oil’. KunKun can detect all four of these and lets you know immediately whenever you stink.
The device doesn’t just notify when you stink; it also tells you how much you stink using a color-coded meter. A stink-0-meter if we may call it. The idea was pitched by Hiroshi Akiyama, a 43-year-old man working in Konika Minolta when he became worried of his body odor. The company then partnered with Osaka Institute of Technology to develop the ‘sniff sniff’ stink-o-meter.
I won't be out til summer, so til then, don't spare the deodorant.
