TL;DR: The Circular Ring 2 is a subscription-free smart ring for $299 (MSRP $449) that tracks 140+ health metrics, explains them with AI, and looks like jewelry, not a gadget.
If you like the idea of tracking your health but hate wearing bulky gadgets, buzzing screens, or juggling yet another app subscription, this smart ring might be your new favorite piece of tech. Circular Ring 2 takes advanced health tracking and shrinks it down into a sleek titanium ring that quietly works in the background — no wrist real estate required.
Circular Ring 2

Instead of flooding you with charts and raw numbers, Circular Ring 2 focuses on clarity. It tracks more than 140 health signals, covering everything from sleep quality and stress levels to heart rhythm, recovery, energy, and activity. Then it hands that data off to Kira, its built-in AI health coach, which translates those signals into simple, actionable insights you can actually use.
The ring itself is crafted from lightweight titanium, weighs just 3 grams, and is designed to be worn all day and night without getting in the way. There’s no screen, no constant notifications, and no distractions — just steady, behind-the-scenes tracking. Battery life stretches up to eight days, and a quick wireless charge gets you back to full in about half an hour.
Circular Ring 2 also stands out for what it doesn’t require. There’s no monthly subscription for core features, and you’re not locked into another recurring charge just to access your own health data. Upcoming premium metrics like blood pressure and glucose trends are on the roadmap, but the foundation is already packed with value.
If you want meaningful health insights wrapped in a piece of jewelry you’ll actually enjoy wearing, this is the ring for you.
The Circular Ring 2 offers a quieter, smarter way to stay in tune with your body for $299 (MSRP $449) for a limited time.
