After debuting its new hypertension notification feature with the Apple Watch Series 11 and Watch Ultra 3 in September 2025, the company is finally bringing the health tracking metric for users in India.
Starting this week, users with the Apple Watch Series 9 or later and Watch Ultra 2 / 3 will be able to access Apple’s passive hypertension-detection system in India.
What’s Hypertension?
The feature is designed to flag early signs of chronic high blood pressure, a condition that affects millions of people in India but often goes undiagnosed. What makes Apple’s approach interesting is that it doesn’t ask users to change anything about how they use their watch.
Instead, it taps into data from the same optical heart sensor used for heart rate tracking and studies how the user’s blood vessels react to each heartbeat.
Apple says the watch runs this analysis quietly in the background, pulling data from a rolling 30-day window. If the algorithm identifies consistent patterns associated with hypertension, the user receives a notification explaining the concern and suggesting next steps.
Apple believes the feature could help more than a million people in India discover they may be living with high blood pressure. The company frames it as a tool to encourage early lifestyle changes or medical treatment before the condition leads to something more serious.
There are limitations, though. The feature isn’t available for users under 22, anyone already diagnosed with hypertension, or pregnant individuals. And of course, it’s not a replacement for medical equipment, just an early nudge from your wrist.
Still, this expansion makes Apple’s health ecosystem feel a lot more proactive. With a massive base of Apple Watch users in India, the rollout brings a meaningful new addition for users.
