The very innovative French startup Circular claims to have revolutionized the wearable market with its Circular Ring Slim, touted as the world’s thinnest and lightest smart ring. Available for pre-order, the ring weighs a mere 2 grams and boasts a thickness of 2.2 mm, delivering a substantial feature set within its compact design.

The Circular Ring Slim focuses on health analysis, incorporating seven biometrics and 142 derived markers captured by a suite of sensors. These sensors include a surface temperature sensor, a three-axis accelerometer for activity assessment, and photo-plethysmo-graphy (PPG) sensors utilizing green, red, and infrared LED light wavelengths to measure various health vitals. The ring tracks heart rate, respiratory rate, blood oxygen levels, and even monitors sleep quality, providing insights into REM cycles and detecting symptoms of illness.

The data collected by the ring is transmitted to Kira+, Circular’s AI assistant, which converts the information into valuable insights and advice. The company emphasizes the accuracy of its data, highlighting its use in clinics and scientific studies.

The Circular Ring Slim offers a six-day battery life, 20 days of onboard memory, and data collection every two minutes, providing 15 times more health data than competitive trackers. Haptic navigation is a notable feature, allowing users to tap inputs for various functions and receive haptic vibrations for feedback and alerts. The ring also features a smart alarm clock that leverages haptic vibrations to wake users at optimal times in their sleep cycles.

Circular aims to make smart rings more prevalent in the wearable market, emphasizing their comfort, resistance, longer battery life, and the ability to wear them alongside traditional watches. The Circular Ring Slim is available for pre-order at a discounted price of $245 (€226), with shipments scheduled for December 15, after which the price will be $275 (€253). Interested customers can place orders on the Circular website.
