On Your Finger. No Screen Required. The PHAEVOX™ CeraRing is a full-featured smart health ring built from premium ceramic — tracking heart rate, blood oxygen, sleep, stress, and daily activity 24/7. Bluetooth 5.2, 5ATM waterproof, magnetic charging. Available in Black, White, and Pink across sizes 6–13. 💓 Continuous Health Tracking Heart rate, SpO2, HRV, stress, and sleep — monitored around the clock without a screen on your wrist. 💧 5ATM Waterproof Rated to 50 metres — wear it swimming, showering, or in the rain without a second thought. 🪨 Premium Ceramic Shell Scratch-resistant, hypoallergenic ceramic that looks like jewelry and performs like a health device. ⚡ Bluetooth 5.2 + Magnetic Charge Low-power BT 5.2 chip keeps it connected efficiently. Magnetic charging — no ports, no fuss. All the Data. None of the Bulk. Smartwatches are obvious. The CeraRing is invisible — it looks like a piece of jewelry and works like a health lab. Worn on your finger where blood flow is strongest, it captures more accurate biometric readings than a wrist-based device. Heart rate variability, blood oxygen saturation, sleep stages, stress levels, step count, calories — all tracked continuously and synced to the QRing app (iOS 9.0+ / Android 5.1+). Gesture control lets you trigger actions without touching your phone. Remote photo shutter, ring finder, female cycle tracking, and ring games round out a feature set that goes well beyond what most wearables offer at this price.
