Summary
Circular introduced the Ring 3 Slim and Ring 3 Pro, adding contactless payments and restoring haptics as it pushes smart rings closer to smartwatch-level features.
The 6.8mm Ring 3 Pro adds FDA-cleared single-lead ECG for atrial fibrillation detection and blood-pressure trend tracking, while both models also track sleep, activity, heart rate, skin temperature and glucose trends.
Battery life is rated at about 10 days for the 5.9mm Slim and up to 12 days for the Pro; payments will support Visa and MasterCard, though Circular has not named a partner or explained app integration.
Pricing, preorders and availability were not disclosed, with details due in coming months; the current Ring 2 starts at $350 and some advanced health features there appear to require a subscription.
The launch comes as Circular tries to differentiate itself in a crowded smart-ring market despite past criticism over transparency on costs and features.
