Circular unveils Ring 3 series with contactless payments and on-finger vibration alerts
Smart ring maker Circular has officially unveiled the Circular Ring 3 series, introducing two distinct models: the advanced Pro and the streamlined Slim. Both rings are designed to integrate seamlessly into daily life, offering a compelling blend of health tracking and innovative new features like contactless payments and haptic feedback. This launch comes amid intensifying competition in the smart ring market, following recent releases from Oura and RingConn.
Circular Ring 3 Pro: Advanced Health Monitoring
The Circular Ring 3 Pro represents a significant leap forward from its predecessor. It boasts a slimmer, more refined design while packing an impressive array of health sensors. Key features include an FDA-cleared ECG for detecting atrial fibrillation (AFib), blood pressure trend tracking, and glucose monitoring. The ring also delivers advanced sleep analysis and comprehensive biometric monitoring, providing users with a complete picture of their well-being.
Battery life has seen a major upgrade as well. The Ring 3 Pro offers up to 12 days of use on a single charge, a substantial improvement from the seven days offered by the previous generation. This extended battery life means less frequent charging and more consistent, uninterrupted health tracking.
Circular Ring 3 Slim: Core Features in a Compact Design
For users who prefer a lighter, more minimalist device, the Circular Ring 3 Slim is an excellent alternative. It is thinner and lighter than the Pro model but still delivers essential health and wellness tracking. This includes monitoring sleep, heart rate, HRV (heart rate variability), SpO₂ (blood oxygen levels), skin temperature, and daily activity levels.
Despite its smaller size and simplified feature set, the Slim model still offers impressive battery life of up to 10 days. Circular CEO Amaury Kosman explained the company’s strategy behind offering two models: “We understand that not everyone wants every health feature. Many people simply want a beautifully designed, fashionable smart ring that delivers essential wellness insights and effortless contactless payments. That’s why we created Circular Ring 3 Slim—a lighter, more streamlined experience that retains the convenience of secure NFC payments while offering the core health tracking features many users want in an incredibly compact design.”
On-Finger Vibrations and Contactless Payments
A standout feature across the entire Circular Ring 3 series is the integration of on-finger vibrations. This haptic feedback system provides a discreet and effective way to receive notifications and alerts. Users can utilize it for silent wake-up alarms that won’t disturb a partner, medication reminders, vital health alerts, and even guided breathing exercises for stress management.
Both the Pro and Slim models are equipped with an integrated NFC chip, enabling secure contactless payments directly from your finger. This functionality adds a new level of convenience to daily life, allowing you to leave your wallet or phone at home for everyday purchases. The payment feature positions the Circular Ring 3 as more than just a health tracker—it becomes a versatile tool for modern living.
Design, Durability, and Available Finishes
The new rings are designed with both style and durability in mind. Both the Ring 3 Pro and Slim are constructed from titanium steel, offering a premium feel and robust build quality. They feature 50-metre water resistance, making them suitable for swimming, showering, and everyday wear without concern. Wireless charging support adds another layer of convenience for users.
Consumers will have a range of finish options to choose from, including gold, rose gold, silver, and black. The rings will be available in sizes 6 through 14, accommodating a wide variety of finger sizes. This extensive sizing range ensures that most users can find a comfortable and secure fit.
Competition in the Smart Ring Market
The announcement of the Circular Ring 3 series comes at a pivotal time. The smart ring market has seen heightened competition over the past year, following the launches of the Oura Ring 5 and RingConn Gen 3. Each of these devices offers its own unique approach to health tracking and wearable technology. By introducing two distinct models, Circular is strategically positioning itself to capture different segments of the market.
The Pro model targets health enthusiasts and users who want comprehensive biometric data, while the Slim model appeals to those who prioritize simplicity, design, and essential wellness tracking. This dual-approach strategy could help Circular differentiate itself in an increasingly crowded field.
Pricing, Pre-Order, and Release Timeline
Circular has confirmed that pricing and preorder information for both smart rings will be announced in the coming months. The company expects the rings to become available in early 2027. While specific pricing details remain under wraps, the feature set and build quality suggest the Circular Ring 3 series will compete in the premium smart ring category.
The combination of advanced health features, innovative haptics, contactless payment capabilities, and extended battery life makes the Circular Ring 3 series a compelling option for both existing smart ring users and newcomers to the category. As the wearable technology market continues to evolve, devices like these represent the growing convergence of health monitoring, convenience, and everyday functionality.
For those interested in upgrading their wearable technology or exploring the smart ring category for the first time, the Circular Ring 3 series offers two distinct paths forward—one packed with every possible health sensor and another focused on core wellness essentials. Both models share the innovative features that set this generation apart: contactless payments, on-finger vibrations, durable titanium steel construction, and long battery life.
