My ring Readings seem inaccurate? Can it be trusted?
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 InaccuracyWearing 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 Do1. Check Wearing Method:Review the user guide or app instructions to ensure correct placement and fit.2. Follow Measurement Guidelines:
