Circular Ring 3: Contactless Payments and Vibrating Alerts

Announcing Circular Ring 3

The Circular Ring 3 is here, and it’s ready to do more than track your sleep. This new generation introduces a practical upgrade: contactless payment capability, letting you pay on the go without pulling out your phone or wallet. It also adds vibrating alerts for notifications and calls, so you can stay connected with a subtle buzz on your finger.

The ring is available in two distinct versions. The standard model includes the full suite of health tools, such as AFib detection. For those who prefer a slimmer profile, there’s the Slim variant, which omits AFib detection to achieve a more discreet form. Both versions maintain the core Circular experience, but the choice comes down to how much health monitoring you want versus how lightweight you need the ring to feel on your hand.

Key Features and Upgrades

The Circular Ring 3 introduces two significant upgrades for daily usability: contactless payments via NFC and vibrating alerts for notifications. This means you can leave your wallet at home for quick taps at terminals, and you’ll feel a discreet buzz on your finger for incoming calls or messages—no need to check your phone constantly.

Two distinct versions of the ring are available, and they differ notably in health tracking capabilities. The key distinction lies in AFib detection (atrial fibrillation). While both models offer core sleep and activity metrics, only the more advanced version includes dedicated AFib monitoring. The standard model focuses on general wellness, whereas the upgraded version adds this specific heart-rhythm analysis for users seeking deeper cardiac insight. This separation ensures you can choose the level of health data that fits your needs, with the premium tier offering that extra layer of proactive heart health tracking.

Slim Model and Health Tracking

The Circular Ring 3 is available in two distinct versions to suit different preferences. The Slim model is designed for those who prioritize a more discreet and lightweight profile on the finger. However, this slimmer design comes with a key trade-off: it does not include AFib detection. For users who want this specific heart-rhythm alert, the standard model is the necessary choice, as it retains this capability.

Beyond that distinction, both versions are equipped with a comprehensive suite of wellness tools. You can rely on continuous heart rate monitoring throughout the day and night. The ring also provides detailed sleep tracking, breaking down your rest stages to help you understand your sleep quality. Additionally, built-in activity tracking monitors your daily movement, steps, and calorie burn, ensuring you stay on top of your fitness goals even with the more minimal Slim option.

Pricing, Availability, and Battery

The Circular Ring 3 is priced at $380 for the standard model, while the Slim variant—which omits the vibration motor and speaker—costs $340. Pre-orders are open now, with a fully refundable $50 deposit required to secure your unit. Shipping is expected to begin in February 2025, with orders fulfilled on a first-come, first-served basis.

Battery life is a standout improvement. The Ring 3 delivers up to 8 days of use per charge, a significant jump from its predecessor. Charging is handled via the included USB-C charging case, which provides an additional 20 days of power on the go. A full recharge of the ring itself takes approximately 80 minutes.

For those on the fence, the company offers a 14-day return policy and a 1-year warranty. You can place your pre-order directly through the official website at circular.ring.
