Circular Ring 2: World’s Most Advanced Health Tracking Ring

You wake up feeling tired. Your smartwatch says you slept 8 hours, but you don’t feel rested. You check your heart rate, but it tells only half the story. What if your wearable could truly understand your body—giving you precise health insights, early warnings, and personalized guidance?

Take control of your health with Circular Ring 2—the most complete health-packed smart ring. 

Get 13+ health features, including tracking of heart’s electrical activity, your steps, AI actionable insights, 140+ biometrics, and real-time tracking—all in a premium titanium design. No bulk, no distractions, and no subscriptions.

Your heart’s health shouldn’t be a mystery. Circular Ring 2 changes the game. In just 30 seconds, you can have your heart’s electrical activity available to you. Circular Ring 2 takes heart rhythm directly from your finger—where signal quality is naturally stronger and clearer. 

For the first time, heart rhythm monitoring fits into something as small and comfortable as a ring.

The Circular Ring 2 integrates Kira, an AI-powered health strategist that learns your unique patterns and suggests exact actions to improve your well-being. Powered by advanced AI and machine learning, it processes over 140 biometric markers, and delivers daily actionable recommendations tailored to your habits, physiology, and lifestyle.

Unlike other rings, Kira actively guides you toward improved health and wellness, making it an indispensable partner in achieving your goals.
Kira is the proactive core of Circular Ring 2’s personalized wellness guidance, setting it apart from competitors that rely solely on passive chatbots.

Kira doesn’t just summarize your data—it contextualizes it. For example:

• Struggling with stress? Kira will suggest breathing exercises or adjustments to your daily routine.
• Poor sleep quality? Kira identifies potential disruptions and offers ways to improve your rest.
• Low energy? Kira correlates patterns in your activity, sleep, and recovery to pinpoint areas to optimize.

You shouldn’t have to pay a monthly fee just to understand your own health. Yet, most wearables put their most valuable insights behind a paywall. Circular Ring 2 is different. With a one-time purchase, you get lifetime access to everything – heart’s electrical activity, sleep tracking, heart rate variability, stress analysis, personalized AI recommendations, scores, leaderboards, and all future features. No recurring fees. No locked insights..

Plus, you’ll benefit from free, frequent updates that continuously enhance your ring’s capabilities. We’ve already released 133 updates to our app and ring, and we’re just getting started. With Circular Ring 2, your investment keeps getting better over time.

Because real health tracking shouldn’t come with a monthly bill. It should come with clarity, control, and confidence – and that’s exactly what we deliver.

The Circular Ring 2 provides continuous tracking of vital health metrics such as heart rate, sleep patterns, stress levels, activity, and recovery.

More than just an alternative, a ring is the future of seamless health tracking.

That means faster shipping, less waste, and a ring that fits like it was made for you. Available in US sizes 6 to 13—so everyone gets the perfect fit, instantly.

Your health changes by the minute—shouldn’t your tracker keep up? Circular Ring 2 captures biometric data every 2 minutes, delivering 5× more granularity than standard wearables. More data means smarter insights—from heart rate and HRV to SpO₂, temperature, and sleep patterns—giving you a clearer picture of your well-being. Detect early warning signs, optimize recovery, and get truly science-backed guidance from Kira, tailored to your unique needs.
