Smart ring maker Ultrahuman is working with the Abu Dhabi Public Health Centre to develop and validate a biological age model aimed at rollout across the United Arab Emirates. The two-year agreement combines clinical biomarkers and wearable-device data to estimate ageing speed and identify factors that accelerate or slow it. Ultrahuman plans a phased expansion after validation but gave no timeline. CEO Mohit Kumar said the focus is on using data, not the ring itself, and that the model will not be trained on UAE data.

Samsung Electronics is expanding the Galaxy Watch’s health management features from individuals to families by adding family profiles to Samsung Health and linking Samsung accounts. Users can selectively share metrics such as steps, sleep, heart rate, blood pressure and blood glucose so relatives can monitor changes and respond. Samsung also highlighted heart-health scoring and sleep-time vital signs tracking, and cited regulatory approvals and cases where alerts prompted medical care.
