Frequently Asked Questions
Is the ring waterproof for swimming?
The JCRing 2301B is designed for daily life with IP68/5ATM-equivalent water resistance. It is safe for hand-washing, rain, and showering. However, we recommend avoiding hot saunas or deep-sea diving to protect the precision sensors.
How does the JCRing 2301B monitor blood glucose risk without pricking my finger?
The JCRing 2301B uses advanced BGEM (Blood Glucose Estimation Model) technology. By utilizing medical-grade PPG optical sensors to track heart rate variability (HRV), skin temperature, and pulse wave patterns, our AI algorithm identifies metabolic trends and glucose risk levels. It is a non-invasive tool designed to help you understand how your lifestyle impacts your glucose health, rather than a clinical diagnostic device.
How long does the battery last and how do I charge it?
A single charge provides approximately 7-10 days of continuous monitoring. The ring comes with a portable wireless charging box; simply place the ring inside and connect the box to a power source via the included Type-C cable.
