Key points regarding the Apple Watch’s health monitoring features include:

  • Heart Rate Monitoring: Uses photoplethysmography (PPG) sensors to detect pulse rate and rhythm.
  • Electrocardiogram (ECG): Available on select models, enabling users to record electrical signals of the heart for arrhythmia detection.
  • Blood Oxygen (SpO2): Optical sensors estimate oxygen saturation in the blood.
  • No Direct Blood Pressure Sensor: Apple Watch hardware lacks the necessary components (such as an inflatable cuff or tonometer) to measure blood pressure directly.

Third-Party Solutions and Workarounds for Blood Pressure Tracking

While the Apple Watch itself does not measure blood pressure, there are indirect methods and third-party devices designed to integrate with the Apple Watch ecosystem or the Health app on iOS:

  • Bluetooth-Enabled Blood Pressure Monitors:

External cuffs from brands like Withings, Omron, and Qardio can connect to iPhones, allowing users to log blood pressure readings that sync with the Health app. These devices operate independently but provide seamless data integration.

  • Companion Apps:

Apps such as Qardio, Withings Health Mate, and Omron Connect enable users to monitor trends over time by importing cuff-based measurements into Apple’s Health ecosystem.
