F.A.Q
Is a paid subscription required to use all JCRing features?
No, a paid subscription is not required. All core features, including health and activity tracking, are available without additional costs.
How long does the JCRing battery last?
The battery lasts between 7 to 10 days, depending on usage. It fully charges in about 2 hours using wireless charging.
How is your ring different from similar ones on the market?
JCRing is developed by a medical device company (JC Health Group), which supports maximum accuracy in the indicators. JCRing offers a unique combination of comprehensive health tracking, including blood glucose monitoring, which is not commonly available in most competing smart rings. It also offers water resistance up to 100 meters and extended battery life of 7 to 10 days. Unlike many competitors, JCRing does not require a paid subscription for full access to all features.
What size is it and how comfortable is it to wear?
The smart ring has a minimalistic, ergonomic design that is comfortable for everyday wear. It is made of lightweight, hypoallergenic materials, and is designed to be worn around the clock, including sports and sleep. It can also be worn for water activities if it is waterproof.
What measures more accurately with a ring or a bracelet?
Finger-based measurements are generally more accurate because blood vessels are closer to the surface, providing clearer signals for sensors. This can make metrics like heart rate and SpO2 more precise than many wrist-based devices, where thicker tissue can interfere with readings.
What devices is JCRing compatible with?
JCRing is compatible with Android and iOS devices, allowing you to sync with most modern smartphones and tablets through the dedicated app.
Can I use JCRing while swimming?
Yes. JCRing is water-resistant up to 5 ATM (up to 100 meters), making it suitable for swimming and other water activities.
What functions does the JCRing smart ring support?
JCRing monitors heart rate (HR), blood oxygen (SpO2), heart rate variability (HRV), stress, mood, sleep, and physical activity. It also supports blood glucose monitoring, temperature tracking, and menstrual cycle monitoring for women.
How does the ring measure blood glucose?
JCRing uses photoplethysmography (PPG) technology for non-invasive blood glucose monitoring, allowing you to monitor changes in blood glucose in real time directly from the ring.
How accurately does the ring track sleep and sleep phases?
JCRing uses advanced sensors to monitor sleep stages, including light, deep, and REM sleep. This helps assess overall sleep quality and provides recommendations for improvement.
Can I use JCRing without being constantly connected to a smartphone?
Yes. JCRing works offline and stores data autonomously. When you reconnect to your phone, the stored data syncs with the app for analysis.
Does JCRing come with a warranty?
Yes. JCRing is covered by a one-year manufacturer’s warranty from the date of purchase.
Can JCRing sync with other apps?
Yes. JCRing can sync with third-party apps such as Apple Health and Google Fit.
