Wellness Score · Circular Ring 2
Circular Ring 2 tracks your sleep, energy, stress, recovery, activity, heart rate, HRV, breathing, temperature, and more, then combines them into one daily Wellness Score. So when you wake up, you know how your body is doing without checking eight separate numbers.
A sleep score of 72. A stress score of 58. An energy score of 81. A recovery score of 64.
None of them tell you what to do today. Most people do not have time to weigh every signal against each other every morning. So they guess. They trust the score that feels most important, or they ignore the data and go by how they feel.
The Wellness Score is not a simple average. Each contributing signal is weighted according to its importance to your overall health, then combined into one daily readout.
Circular Ring 2 collects your data continuously, then processes your overnight sleep data alongside the previous day's activity, stress, and recovery signals. Every morning, you get one score measured against your own personal baseline, not a generic population average.
Your number sits front and center the moment you open the app.

Track your Wellness Score across 7 and 30 days to see whether your body is improving, declining, or holding steady.

Kira AI
A number alone does not tell you what to do with it.
Kira, Circular's AI health coach, reads your Wellness Score alongside its contributing signals and tells you what is driving the change in plain language.
When your HRV and breathing rate dip together, Kira tells you that instead of leaving you to find the pattern yourself. When your score climbs, Kira can help you connect it to what you actually changed.
Example:
“Your HRV and breathing rate are both down this morning. Consider pushing today's workout to tomorrow.”
Circular Ring 2 combines a wide range of physiological signals into one daily Wellness Score, with Kira AI recommendations included at no ongoing cost.
You feel okay, but your score says otherwise. Kira AI shows HRV and breathing rate are both down, so you move the hard workout and protect recovery before your body forces you to.
You have been pushing through work stress for days. Then you notice eight straight days under 75. The pattern makes it clear: this is not one bad morning. It is cumulative strain, and your body needs a real weekend off.
Your score drops after travel, then slowly starts climbing back. Instead of guessing when you have adjusted, you can see how many days your body actually takes to recover from the time zone shift.
You compare the 30 days before and after cutting back. Sleep quality, HRV, and recovery start moving in the right direction. The score turns a vague “I think I feel better” into something you can actually measure.
Your score stays low while your body is still under strain, then climbs as your recovery returns. One trend line makes it easier to know when to rest, when to move lightly, and when you are ready to push again.
Instead of bringing eight separate charts, you bring one clear trend and the signals behind it. It makes patterns easier to explain, easier to review, and easier to act on.
Your Wellness Score connects data from sleep, stress, recovery, heart rate, HRV, temperature, activity, ECG, SpO₂, breathing patterns, and Energy Score. These features work together, so your daily score is not built from one isolated metric. It reflects the wider state of your body.
The Wellness Score uses HRV, resting heart rate, breathing rate, SpO₂, temperature variation, sleep quality, wake-up score, recovery, activity, stress, and Energy Score.
The score is measured against your own baseline, not a generic population average. This helps Circular detect when your body is shifting away from your normal pattern.
Circular processes your overnight data together with the previous day's activity, stress, and recovery signals to generate one daily score.
90+ means excellent. 80–89 means good. Below 80 means your body may need more recovery.
Circular Ring 2 is not a medical device. The Wellness Score does not diagnose illness, detect disease, or predict medical outcomes. It is a wellness feature designed to support daily awareness.

The Wellness Score reflects your overall physiological state, built from your tracked signals and compared against your personal baseline. It is designed to support proactive awareness and help you make better day-to-day decisions about effort and recovery.
It does not diagnose any condition, detect illness, predict medical outcomes, or replace a conversation with a doctor.
★★★★★
"I used to trust how I felt. Score sat at 61 one morning when I felt completely fine. HRV and breathing rate were both down. Moved the workout. Good call, turns out."
★★★★★
"Eight days under 75 in a row. I had been pushing through a stressful work stretch and telling myself it was fine. The streak made it impossible to ignore. Took a proper weekend off. Score was back above 80 by Monday."
★★★★★
"Six months in. Mostly I just check the number, read Kira's line, and get on with my day. Which is the whole point really."

The Wellness Score is one daily health score built from your sleep, stress, recovery, activity, heart rate, HRV, breathing, temperature, and energy data. It gives you a simple read on how your body is doing overall.
No. They are related, but not the same. The Energy Score is one of several signals that feed into the Wellness Score. The Wellness Score takes a wider view across sleep, cardiovascular, respiratory, temperature, recovery, stress, activity, and energy data.
No. Recovery is part of the Wellness Score, but the Wellness Score looks beyond recovery alone. It also considers sleep, stress, activity, energy, heart rate, HRV, breathing rate, SpO₂, and temperature variation.
The score uses HRV, resting heart rate, breathing rate, SpO₂, body temperature variation, sleep quality, sleep balance, wake-up score, weekly activity volume, body recovery, Energy Score, and Stress Score.
Yes. Sleep data is one of the key inputs, so overnight wear is important for an accurate Wellness Score.
The score becomes more useful as your personal baseline builds. Kira AI uses your own data across the first couple of weeks, then continues to refine insights the longer you wear the ring.
Your score may drop when your body shows signs of strain, such as lower HRV, higher resting heart rate, poor sleep quality, elevated stress, temperature changes, lower recovery, or heavier activity load. Kira AI helps explain which signals are driving the change.
Yes. Your body can show strain before you notice it. A lower score may reflect changes in HRV, breathing rate, temperature, stress, or recovery that are not obvious yet.
Sometimes. One bad signal does not always define the whole score. If other signals like HRV, recovery, stress, and activity load are stable, your overall Wellness Score may stay in a healthy range.
Kira surfaces meaningful drops and patterns as part of your daily check-in. Instead of just showing a low number, Kira explains what changed and what you can do next.
Yes. You can track your score across 7 and 30 days to see trends, patterns, and changes in your baseline.
No. Wellness Score and Kira AI daily recommendations are included with Circular Ring 2 as part of the core feature plan, with no ongoing subscription required.
Yes. The Wellness Score can help make your health patterns easier to explain. Instead of showing separate charts for sleep, HRV, stress, and recovery, you can show one trend line and the signals behind it.
No. Circular Ring 2 is not a medical device. The Wellness Score is a wellness feature. It does not diagnose illness, detect disease, predict medical outcomes, or replace medical advice.
