Circular, makers of the Circular Ring Pro smart ring, has launched the Circular Ring Slim, which it says is the thinnest and lightest smart ring on the market, and purportedly the first to also incorporate haptic navigation and alerts.
Paired with Kira+, Circular’s AI wellness assistant, the sleek Circular Ring Slim assesses seven biometrics and 142 derived markers 24/7 to help people sleep better and live healthier lives. By optimizing physical activities and maintaining mental wellness, the Ring focuses on personalized, preventative health.
As the company’s second smart ring, the Circular Ring Slim is, like the inaugural model, designed to be used and worn constantly. It measures 2.2mm thin and weighs just 2 grams. It offers precise health tracking via a suite of advanced sensors. It comes equipped with a three-axis accelerometer count that assesses activity and movement, and a surface temperature sensor. Advanced PPG sensors combine 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.
With a six-day battery life and 20 days of on-board memory, Circular Ring has a matte black titanium shell. It collects health data every two minutes and, over time, helps build a picture of overall health as well as predict potential health conditions.
During the day, the ring captures activity, blood oxygen levels, energy levels, calories burned, heart rate, respiration rate, and chronotype, among other metrics. 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.
The Circular Ring Pro button is replaced on the Circular Ring Slim with a complete haptic navigation interface. 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 you at the optimal time in the sleep cycle with gentle vibrations. There are also medication reminders, providing alerts when it is time to take medicine and guided breathing exercises, providing prompts to inhale, hold, and exhale for calming breathing exercises and improved sleep hygiene.
To make actionable sense of the wealth of data collected by the new slim version of the Circular Ring, it is connected to Kira+, an AI-powered conversational health and wellness assistant. Kira+ is trained with millions of health data points and leverages the latest generative AI language models. It provides personalized health information and recommendations in a reliable and relatable way, says the company.
Kira+ continually analyzes the ring’s data and gets to know you over time. Over a 14-day period, Kira+ asks questions about daily habits and preferences to set a base level. Based on an in-depth analysis of your parameters, chronotype, digital biomarkers, and health goals, Kira+ then delivers personalized health recommendations and analyses tailored to individual users. The best part? There are no monthly subscription fees.
Getting better over time, Kira+ also assesses the multitude of biomarkers monitored to predict potential health lifestyle or nutritional issues before they occur. It even offers an early warning system for detractions in medication compliance.
Kira+ also provides motivation through gamification strategies, challenges, leaderboards, and even the ability to earn financial rewards through the Circular Coin program. By achieving health or activity goals, you can earn Circular Coins, a digital currency that can be exchanged for Circular’s products and services such as outer shells, chargers, cable, rings, premium app features, or trusted third party products and services.
The Circular app is compatible with a range of other health apps, including Google Fit and Apple HealthKit.
The Circular Ring Slim is available for pre-order at the discounted price of US$245 and will ship on December 15, 2023. From December 15, 2023, onwards, it will be priced at US$275.
