Frequently Asked Questions

Q: Why is the Circul Ring’s data more accurate?

Four key reasons:

  1. SST sensor technology that is certified by the FDA.

  2. Adaptive-Fit technology ensures continuous and stable contact with your skin.

  3. Real-time updates every second, unlike other smart rings that only sample data at one-minute intervals.

  4. Clinically validated through years of medical research and testing.

Q: Is the CIRCUL RING continuously monitoring my health?

Yes, the CIRCUL RING provides near-medical-grade health data with real-time tracking at second-level intervals. It supports continuous monitoring for certain metrics such as heart rate, HRV, stress, and energy levels throughout the day. Other metrics, like blood pressure, activity, exercise heart rate, sleep monitoring, sleep apnea tracking, and continuous blood oxygen, are monitored during specific time periods or under certain use conditions.

Q: What metrics does Circul Ring track?

Sleep Apnea monitoring

Blood Pressure

Blood Oxygen Levels (SpO2)

HRV monitoring

Heart Rate (Realtime monitoring)

Temperature

Real-time Sleep Monitoring

Activity Tracking

Steps and Movement

Energy & Stress

Q: How long does the battery last?
The CIRCUL RING features medical-grade tracking at 1-second intervals. Due to the increased power consumption from these intensive calculations, the battery life in this mode is approximately 7~9 days per charge. 🔋
Q: What materials are used to make the ring?

Stainless steel with PVD coating. Unlike traditional smart rings that make fingers sweat, this one stays dry and comfortable. Crafted like a luxury watch, it fits every setting—business or casual—with refined elegance.

Q: How to claim the extended warranty?

Automatically applied to all orders placed in August on this sale page.
