Apple Watch Ultra 4 to Offer More Accurate Blood Pressure Monitoring

Apple is preparing the Apple Watch Ultra 4 with a refined cuffless blood‑pressure detection system. According to the industry source Digitimes, the next‑generation watch will feature eight ring‑arranged sensors on its back that use the optical heart sensor to analyse how blood vessels react to individual heartbeats. When abnormal patterns are detected, the watch can alert users to a possible hypertension risk, improving on the current “Hypertension‑Hints” that only flag trends over a 30‑day period.

In parallel, Apple’s forthcoming iOS 27 beta expands the role of AirPods Pro 3 in fitness tracking. The update adds GymKit support, letting the earbuds capture complete workout data—such as distance, pace and heart‑rate—by simply tapping an iPhone to NFC‑enabled gym equipment. Tests show the AirPods can record activity rings without a smartwatch, a move that could reduce the need for an Apple Watch during gym sessions. Both developments illustrate Apple’s strategy to broaden health monitoring across its wearable lineup.
