Circular, pioneers of smart ring technology, is excited to unveil the Circular Ring Slim, the thinnest, and lightest, most intuitive smart ring in the world and the first to incorporate haptic navigation and alerts. Paired with Kira+, Circular’s powerful AI wellness assistant, the sleek Circular Ring Slim assesses 7 biometrics and 142 derived markers 24/7 to help people sleep better and live healthier lives. By optimizing physical activities and maintaining mental wellness it is making personalized, preventative health a reality.
Circular is creating the next generation of remote monitoring solutions for consumers and health professionals built into the most wearable wearables – elegant, high-performing smart rings. The Circular Ring Slim is the company’s second smart ring, following in the footsteps of its original Circular Ring Pro. Both are designed to be used and worn constantly, providing a full circle of health information and delivering on the promise of proactive, personal health.
Circular Ring Slim – Miniature but Mighty
Measuring 2.2 mm in thickness and weighing only 2 grams, the Circular Ring Slim is the slimmest and lightest wearable in the world. It is also one of the most precise health trackers available, thanks to a suite of advanced sensors. It has a three-axis accelerometer count that assesses activity and movement, a surface temperature sensor, and advanced PPG sensors combining three different LED light wavelengths, green, red, and infrared, to capture a range of health vitals such as heart and respiratory rates, blood oxygen levels and heart rate variability.
There is no screen or display, so everything is handled via the companion smartphone App which is compatible with both Apple iOS and Google Android.
Battery and Storage
With a 5-day battery life and 20 days of on-board memory, Circular Ring is designed to be constantly worn day and night. Its ultra-thin design ensures maximum comfort, and its mat black titanium shell makes it a perfect accessory for any social or business setting. It collects health data every 2 minutes to provide 15 times more health data than competitive trackers. By being continuously worn, Circular Ring Slim helps build a picture of overall health and can help predict potential health conditions. The Circular Ring Slim is also suitable for light water exposure like showering or washing hands but not for swimming.
During the day, the ring captures activity, blood oxygen levels, energy levels, calories burned, heart rate, respiration rate, and chronotype, among other metrics, while at night, the ring ambiently tracks circadian rhythm and records sleep quality, heart rate variability, sleep disturbances, REM cycles, and sleep and wake times. Its sensors measure temperature variations during sleep, which, combined with other biometrics, can provide a clearer picture of immune systems and provide early detection of the onslaught of illness.
It comes with a Micro-USB charging connector you can keep with you and charge the ring when it runs low. The Circular Ring takes approx 45mins to charge.
As well as being the slimmest smart ring available, it is also the first to feature both haptic navigation and feedback. The Circular Ring Pro button is replaced on the Circular Ring Slim with a complete haptic navigation interface. Users select various functions by tapping inputs anywhere around the ring. Haptic vibrations are also used to provide feedback and alerts and drive a number of features, including a Smart Alarm Clock that will gently wake a person at the optimal time in the sleep cycle with gentle vibrations, Medication Reminders providing alerts when it is time to take medicine and Guided Breathing Exercises, providing prompts to inhale, hold and excel for calming breathing exercises and improved sleep hygiene.
