Frequently Asked Questions
What makes the JCRing X3 different from other models?
The X3 is our premium medical-grade smart ring, featuring higher-precision sensors and advanced algorithms for:
- Medical-class SpO₂ (blood oxygen) monitoring
- Comprehensive HRV and stress analysis
- Non-invasive blood glucose risk trend assessment
- VO2 Max estimation for cardio fitness level
- Advanced AI-powered health risk alerts
Does the X3 really monitor blood glucose?
The X3 provides non-invasive blood glucose risk trend monitoring (estimated trends and fluctuations based on multi-parameter data like HRV, temperature, and pulse wave analysis). It does not give exact mmol/L or mg/dL readings like a finger-prick glucometer. Ideal for long-term trend watching in pre-diabetes, diabetes management support, or metabolic health awareness. Always consult a doctor for medical decisions.
Who is the JCRing X3 best suited for?
People focused on cardiovascular and metabolic health
Pre-diabetic or diabetic risk individuals
Middle-aged & seniors wanting medical-grade accuracy
Serious fitness users who want VO2 Max and recovery insights
Anyone seeking the most advanced health warnings & reports
What health metrics does the X3 track 24/7?
Heart rate, HRV, SpO₂, stress level, skin temperature, sleep stages (deep/light/REM/awake), activity & steps, calories burned, breathing rate trends, and OSA (sleep apnea) risk screening.
Is the X3 waterproof for swimming?
Yes — 5ATM rated. Safe for showering, rain, hand washing, and shallow swimming (≤1 meter depth, ≤30 minutes). Avoid hot tubs, saunas, diving, or prolonged saltwater exposure.
Battery life and charging?
Up to 7 days of typical use on a single charge. Full charge takes ~1.5–2 hours via the included wireless charging case.
