No, a paid subscription is not required. All core features, including health and activity tracking, are available without additional costs.

The battery lasts between 7 to 10 days, depending on usage. It fully charges in about 2 hours using wireless charging.

JCRing ring is developed by a medical device company JC HEALTH GROUP, which gives 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. In addition, its superior water resistance of up to 100 meters, extended battery life of 7-10 days, and integrated features like real-time ECG tracking and blood pressure monitoring make it one of the most feature-rich devices in its class. Unlike many competitors, JCRing does not require a paid subscription for full access to all features, providing excellent value without ongoing costs.

The smart ring has a minimalistic and ergonomic design, making it comfortable for everyday wear.
The ring is made of lightweight, hypoallergenic materials, making it almost invisible on the finger. Thanks to its clever design, it does not restrict movement and can be worn around the clock, including playing sports, sleeping or even swimming if it is water resistant.

Measurements taken from the finger are generally more accurate because the blood vessels in the finger are closer to the surface, providing clearer signals for sensors to detect. This makes monitoring metrics like heart rate, blood oxygen (SpO2) more precise compared to wrist-based devices, where thicker tissue can interfere with the readings.

JCRing is compatible with Android and iOS devices, allowing users to sync the ring with most modern smartphones and tablets through a dedicated app.

Yes, JCRing is water-resistant up to 5 ATM, allowing it to be submerged to depths of up to 100 meters, making it ideal for swimming and other water activities.

JCRing monitors heart rate (HR), blood oxygen levels (SpO2), heart rate variability (HRV), stress levels, mood, and sleep, as well as physical activity. It also supports blood glucose monitoring, temperature tracking, and menstrual cycle monitoring for women.

JCRing uses photoplethysmography (PPG) technology for non-invasive blood glucose monitoring. This safe method allows you to monitor changes in blood glucose in real time directly from the ring.

JCRing uses advanced sensors to monitor sleep stages, including light, deep, and REM sleep. This helps assess your overall sleep quality and provides recommendations for improvement.

Yes, JCRing works offline and stores data autonomously. Once the ring is connected to your phone, all the stored data syncs with the app for analysis.

Yes, JCRing is covered by a one-year manufacturer's warranty from the date of purchase

JCRing offers the ability to sync your data with several third-party apps, such as Apple Health and Google Fit.
