Apple has activated its passive hypertension detection feature for Apple Watch users in India, marking a significant step in expanding its health monitoring capabilities. This feature, initially launched globally in September 2025, now supports not only the Apple Watch Series 11 and Ultra 3 but also Series 9 and Ultra 2, making it accessible to a broader audience in a country heavily affected by cardiovascular diseases.
Hypertension, often called the "silent killer," frequently shows no symptoms until serious complications occur. Over 30% of India’s adult population suffers from high blood pressure, with half unaware of their condition. Apple’s innovation could serve as an early warning system that encourages proactive health management before critical events like strokes or heart attacks.
How the Hypertension Detection Works
The standout aspect of this feature is its passive nature. Apple Watch users do not need to activate any specific mode or use special equipment. The watch utilizes an optical photoplethysmography (PPG) sensor already embedded in the device to record heart rate data continuously.
Beyond measuring simple heart rate, Apple’s AI algorithms analyze pulse transit time (PTT) — the time it takes for a blood pressure pulse to travel from the heart to the wrist — and other waveforms. High blood pressure typically shortens this transit time due to increased arterial stiffness. Data is collected over 30 days during sleep or light activities, then encrypted and processed on Apple’s cloud servers to detect risk patterns.
If the watch identifies signs of potential hypertension, it provides the user with a private notification containing detailed explanations, recommendations for blood pressure monitoring, advice to consult healthcare professionals, and lifestyle tips such as reducing salt intake and increasing physical activity.
It is important to understand that this feature is predictive rather than diagnostic. It does not replace traditional blood pressure monitors or professional medical evaluations but serves as a health prompt that encourages early detection.
Supported Devices and User Limitations
Currently, the hypertension detection feature is compatible only with Apple Watch Series 9, Series 11, Ultra 2, and Ultra 3. The Apple Watch SE, lacking the newest PPG sensor and processing power, does not support this functionality.
Moreover, Apple restricts the feature’s use for specific groups:
- Individuals under 22 years old, due to their low risk for hypertension.
- Users already diagnosed with hypertension, since the feature focuses on early detection, not ongoing monitoring.
- Pregnant women, because physiological changes during pregnancy can affect data accuracy.
Apple emphasizes that this is not a medical device but a wellness tool designed to enhance users’ awareness about cardiovascular health.
Why India Was a Priority for Expansion
India faces one of the highest hypertension burdens globally, with an estimated 200 million adults affected. Yet only 12% have been diagnosed, and fewer than 10% achieve proper control. Limited healthcare access in rural and densely populated urban areas creates challenges for early diagnosis.
With a growing middle class and increasing smartwatch adoption, India presents a unique opportunity for Apple to scale its health solutions effectively. By integrating pressure trend detection on wearable devices, Apple aims to elevate its Watch from a lifestyle gadget to a vital health companion in emerging markets.
When Will Indonesia Get the Feature?
As of early December 2025, Apple has not officially announced the hypertension detection feature’s arrival in Indonesia. However, since the service is active in over 150 countries, including Malaysia, Vietnam, and the UAE, Indonesia is likely next in line.
Several factors may delay the rollout:
- Validation and calibration of the algorithm for Indonesia’s diverse population.
- Regulatory approvals from the Ministry of Health or BPOM (Indonesia’s Food and Drug Authority).
- Readiness of local healthcare infrastructure to support follow-up interventions after alerts.
Apple Watch users in Indonesia should ensure their devices run the latest watchOS version and watch for new options related to blood pressure trends or hypertension notifications within the Health app settings.
A Broader Vision: Apple’s Health Monitoring Ecosystem
Hypertension detection adds to Apple Watch’s growing suite of health features that include:
- Electrocardiogram (ECG) monitoring.
- Irregular heart rhythm (AFib) notifications.
- Blood oxygen (SpO2) tracking.
- Fall detection and emergency alerts.
- Body temperature sensing for ovulation prediction.
This continuous innovation reflects Apple’s ambition to make the Apple Watch a comprehensive personal health hub. The passive, user-friendly design ensures that health surveillance runs unobtrusively, aligning with Apple’s philosophy of technology serving human needs seamlessly.
For countries like Indonesia, integrating Apple’s predictive hypertension alerts could enhance public health outcomes by bridging gaps in early diagnosis and ongoing health engagement. Although not a substitute for medical devices, this feature represents a meaningful step towards proactive cardiovascular care at the population level.
