There’s an app for that. Japanese tech company Konica Minolta has created a device called Kunkun Body that, when pressed behind your ear, analyzes your bacteria and sweat to determine if you stink or not. It then sends the data to your smartphone so you can sneak off to the nearest bathroom and re-apply your deodorant if you need to. The company has no plans to sell the the device outside of Japan … yet … but chances are you’ll be able to pick up one of these online very soon. Until then, you might have to rely on a good friend to tell you if things are getting a little ripe or if you’re still fresh as a daisy!
