Combined with PPG technology, it monitors heart rate and blood oxygen levels. An AI algorithm generates diagnostic reports, identifying 12 abnormal patterns (e.g., sinus rhythm, atrial fibrillation, premature beats) and offering personalized suggestions based on sleep and exercise data.

• Heart Rate Monitoring: Continuously monitors heart rate fluctuations and other parameters to track heart function and detect abnormal conditions promptly.

• Blood Oxygen Saturation Monitoring: Provides round-the-clock intelligent blood oxygen measurement to help you monitor for oxygen deficiency.

• Blood Pressure Monitoring: Connect to the app to view measurement data and trends in blood pressure, aiding in understanding your patterns and developing healthy habits.

• Scientific Sleep Monitoring: Monitors various sleep states including deep sleep, light sleep, REM, and wakefulness. It provides an in-depth evaluation of your sleep quality to help develop good sleep habits.

• Blood Glucose Monitoring: The smart ring can monitor your blood glucose data in real time, automatically synchronized to the mobile app. You can intuitively view the blood glucose change curve to understand your levels and physical condition. Note: This product is not a medical device. The health data provided is for reference only and shall not be used as a basis for diagnosis or treatment.

6. Specifications

6.1 How to Measure Your Finger Size

To ensure you select the correct ring size, follow these steps:

1. Step One: Wrap a paper strip around the positions of the joint and the root of the finger on which the ring will be worn, forming one circle. (Note: There may be differences in sizes between the left and right hands. Measure the ring size according to the finger on which the ring will be worn.)
2. Step Two: Adjust the paper strip to a comfortable position and make a mark at the intersection. (Note: It should fit closely to the knuckle and the root of the finger. It should neither be too tight nor too loose.)
3. Step Three: Measure the length of the paper strip and take the larger value. Refer to the 'Finger Circumference' in the size chart (Figure 17) to find the corresponding ring size. (Note: The measurements at the top and the joint of the finger may be different. It is recommended to refer to the larger circumference.)

7. User Tips

• For the most accurate measurements, ensure the ring is worn correctly and snugly on your chosen finger.
• Regularly sync your SmartRing with the companion app to keep track of your health trends and access detailed reports.
