PhenomeTech Ceramic Ring
The PhenomeTech Ceramic Ring pairs precision health tracking with the refined durability of ceramic. The shell is scratch resistant, hypoallergenic and noticeably light, so it reads as jewellery rather than hardware while advanced PPG optical sensors work underneath. It tracks sleep duration and rest quality, heart rate, resting heart rate, heart rate variability, blood oxygen (SpO2), respiratory rate, skin temperature trends for early signs of change, steps, distance and calories, and combines them into a daily Capacity Score for recovery and readiness. Battery life is 5 to 7 days from a magnetic charging dock, and the ring is water resistant to 3ATM. It syncs over Bluetooth to the free Phenome app on iOS and Android, with no subscription. Data is encrypted in transit and at rest, UK GDPR compliant and never sold. Sizes 6 to 13, with a free sizing kit available.
