Circular launches a wellness smart ring that tracks your activity, heart rate and monitors your sleep

Circular is a smart ring and wellness wearable that tracks how you respond to your activities, daily choices and body rhythms and offers personalized recommendations to improve your overall lifestyle. The ring is now available on Kickstarter.

Various wearables have hit the market in the past few years. However, many of them are bulky, gadget looking, lack personalization and deliver raw data without telling you how to act upon it. So, the makers of Circular created a smart ring that is “The most advanced wellness smart ring.”

“Our main focus is to make sense of these data. Your metrics are compared to your own averages and baselines to craft very personal suggestions,” says Amaury Kosman, CEO of Circular.

The ring is scratch-resistant and water-resistant. The interchangeable shells, made of polished titanium, allow you to change the look of the ring to fit your style. Circular is stylish and feather weight, weighing only 4 grams.

“At Circular, the idea was to create a device that would be your everyday life companion – from the beginning of the day by waking you up with a smart alarm, to a sleep analysis at the end of the day,” says Kosman. “We also wanted a device that could help combat sleep inertia, to help with a user’s sports sessions with deep activity metrics and unique insights, to even getting notifications directly on your finger.”

Kira is an AI-powered intelligent assistant who provides smart personal insights to help you getting into optimum health.

The ring tracks both your day and night activities to calculate unique scores such as heart rate variability (HRV), energy level scoring and advanced tiredness calculations. All of these metrics are then compared to your own baselines to give you unique recommendations. While you’re sleeping, Circular tracks your sleep and helps improve your sleep quality using sleep metrics.

The silent smart alarm smoothly wakes you up during the light sleep stage without disturbing your surroundings by using silent vibrations.

Circular has built-in data storage. Paired with the Circular app, customized features include smart alarm clock, sleep analysis, activity analysis and alerts.

The company is planning to add more features in the coming days.
