So you are self-conscious about body odor and don’t exactly trust your nose when it comes to it? The Konica Minolta Kunkun Body Odor Checker may be able to help. It is a smart little gadget that can measure 3 types of smells. It combines with your iOS/Android device and lets you know when you don’t smell pleasantly.
The battery life lasts up to 10 hours. The bad news? Something like this isn’t exactly cheap.
