Joule Transforms Earrings Into Fitness-Tracking Wearables

Ontario, Canada-based BioSensive Technologies Inc. is set to begin shipping Joule, its new earring back fitness wearable.

The bite-sized wearable allows women, or anyone wearing earrings, to capture and store their fitness data without the hassle of wearing a wrist-based fitness tracker. And the company website boasts that Joule is the world’s “smallest” and “lightest” fitness tracker.

Joule earring backs can track heart rate, calories burned, steps taken and overall activity level. The small one-size-fits-all wearable also allows users to try to stay within their target heart rate zone by imputing personal body and fitness metrics. The Joule app stores user data via Bluetooth 4.0 and is available for both iOS and Android.

BioSensive’s patent-pending Joule technology is three years in the making and is based on its previous full earring fitness tracker, Ear-O-Smart. In 2014, Ear-O-Smart failed to reach its Kickstarter funding goal.

Joule’s target market are people less inclined to wear more clunky and less fashionable fitness wearables, especially when they are not “working out.” The company hopes Joule users will gain a better, more complete understanding of their health by wearing the tracker all day.

The tech-filled earring backs are smaller than a dime and weigh roughly 1.5 grams. Joule fitness wearables can last for a day when fully charged by its portable charging case. One wearable earring back costs $88 and comes with a 12-month warranty.

Joule will ship its first batch of earring backs on April 18.
