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.
