Introducing Joule Earring Backings!

Universal smart earring backing that you can pair with your existing post-styled earrings to monitor your health.

Heart Rate

Workouts are more effective if one can maintain the heart rate within a target zone by monitoring the workout sessions. Joule helps you to achieve the best result for your workout, by providing you the heart rate information while you are working out.

Calories Burned

One burns only around 180 calories for one hour of workout session in the gym, whereas more than 2000 calories are burned throughout the day. Joule tracks the calories burnt not only when you are exercising, but also accounts for the missing 90% daily caloric expenditure.

Activity Level

Joule helps you to keep track of your activity level, day after day. Joule is connected to your smartphone via Bluetooth, thus syncing your activity throughout the day.

Comfortable and Discrete

Joule is not only the world's smallest fitness tracker, but also the lightest tracker in the world. Our disruptive patent pending technology, is the result of more than 3 years of research and development.
