Overview
- Circular introduced two new models: the Ring 3 Pro, which includes an FDA-cleared on-device ECG for atrial fibrillation detection, and the Ring 3 Slim, a smaller, lighter version that omits the onboard ECG to prioritize size.
- Both rings restore vibrating haptic alerts for silent alarms and reminders and add NFC contactless payments so wearers can pay with a finger tap.
- Circular said basic functionality will remain subscription-free while users must opt into a paid subscription to enable new blood-pressure trend tracking and glucose monitoring features.
- Battery life targets rose versus the Ring 2, with the Pro rated up to 12 days and the Slim up to 10 days, and both models use titanium construction, 50-metre water resistance, and wireless charging.
- The announcement follows a wider industry move to jewelry-like smart rings and signals growing competition to combine everyday payments with clinical-grade health features; both new rings are expected to ship in 2027 with pricing and exact dates to be announced.
