Many women may not warm up to wearable fitness trackers lacking style and femininity. BioSensitive Technologies kept that in mind when developing the Ear-O-Smart. Never mind dangling a band around your wrist. Try on a pair of earrings that can pick up your body’s biorhythms such as heart rate and calorie intake. The data is immediately available to read on an app on your smartphone. Although currently seeking funding on Kickstarter, Ear-O-Smart wants to ship you a kit next summer that will let you customize the jewelry. Current pricing for a pre-order is starting around $110.
