alerts Starting today – Starting today, Apple Watch users in India will have access to a new high blood pressure notification feature that can alert them if symptoms of chronic high blood pressure are detected. The feature uses machine learning algorithms to analyze PPG (photoplethysmography) data from the watch’s optical heart sensor over a 30-day period. It is specifically designed for users with undiagnosed high blood pressure – the Apple Watch will not measure blood pressure directly or display readings on the watch face.

Apple cardiologist Dr. Adam Phillips, who helped develop the hypertension feature, told Indianexpress.

com that the feature is also built on three core principles related to the company’s health. “One is that our features are rooted in science.

That means we develop them and validate them clinically with the most rigorous scientific standards. These features are actionable – when we send a notification, we want to reach the right person at the right time with the right action associated with it.

And we do everything with privacy at the core,” he said.
