Users occasionally feel their Circul Ring readings—such as steps, blood oxygen, blood pressure, or sleep data—may not be perfectly accurate. This is a common concern shared by users of many smart rings and smartwatches. Here are some important points to understand:
Possible Reasons for Inaccuracy
Wearing Position and Fit:
The ring must be worn snugly but comfortably on the correct finger. Too loose or too tight, or wearing it on a different finger than recommended, can affect sensor contact and data accuracy.
Movement and Activity During Measurement: For accurate blood pressure and oxygen readings, it is important to stay still and relaxed during measurement. Movement, talking, or muscle tension can cause fluctuations.
Individual Differences: Skin tone, finger shape, and individual physiology may affect sensor readings. This is a known challenge across all wearable devices.
Sleep Monitoring Limitations: Sleep tracking estimates stages based on movement and heart signals, which may not perfectly match clinical sleep studies. Battery usage can also impact duration and data completeness.
Environmental Factors: Cold fingers, poor circulation, or ambient lighting can sometimes interfere with optical sensors used for heart rate and oxygen measurements.
What You Can Do
1. Check Wearing Method:
Review the user guide or app instructions to ensure correct placement and fit.
2. Follow Measurement Guidelines: Stay still and relaxed during readings, especially for blood pressure and oxygen.
3. Keep Firmware and App Updated: Updates often improve sensor algorithms and data processing.
4. Consult FAQs and Support: Visit our FAQ pages or contact support@circulsense.com for personalized help.
Important Note
These variations are common to most wearable health devices and do not indicate product defects. The Circul Ring uses advanced AI and medical-grade sensors to provide more accurate data possible within the limits of non-invasive wearable technology.
We encourage users to use the Circul Ring as a helpful tool for ongoing health awareness rather than a replacement for clinical measurements. If you have health concerns, please consult a healthcare professional.
