Blood pressure monitoring on the Apple Watch has been rumored for at least four years. According to new supply-chain reports from analyst Ming-Chi Kuo and corroborating evidence in iOS 20 beta code, the Apple Watch Series 11 may finally deliver it.

How it works

Apple's approach is not a traditional cuff-based measurement. Instead, the Series 11 will reportedly use a combination of:

  • Photoplethysmography (PPG): Enhanced optical sensors that measure blood volume changes in the wrist
  • Ultrasonic sensors: New hardware that measures arterial wall thickness and blood flow velocity
  • Machine learning calibration: The watch will require an initial calibration against a standard blood pressure cuff, then use AI models to estimate ongoing readings

The system is described as a "trend monitoring" tool rather than a diagnostic device. It will not give you an exact systolic/diastolic reading like a medical cuff. Instead, it will:

  • Alert you if your blood pressure appears elevated above your personal baseline
  • Track trends over days and weeks
  • Notify you if readings suggest you should see a doctor
  • Log data in the Health app for sharing with healthcare providers

This is similar to Samsung's approach on the Galaxy Watch 7 and Galaxy Watch Ultra, which offer blood pressure estimation with cuff calibration in supported markets.

FDA clearance status

Apple has reportedly been working with the FDA on De Novo classification for this feature — a regulatory pathway for novel devices. The FDA submission was reportedly filed in Q4 2025, and clearance is expected by mid-2026, ahead of the September launch.

If cleared, Apple would join Samsung as the only major smartwatch brands with FDA-authorized blood pressure features. Samsung's implementation is currently available only in South Korea and a handful of other markets, so Apple's global rollout could be a significant competitive advantage.

Other expected features

Beyond blood pressure, the Series 11 is expected to include:

  • S11 chip: Built on TSMC 3nm, with improved neural engine for health AI
  • Larger battery: ~10% capacity increase for all-day blood pressure monitoring without excessive battery drain
  • Sleep apnea detection: An expansion of the respiratory monitoring introduced in watchOS 11
  • Temperature sensing improvements: More accurate cycle tracking and illness detection
  • New satellite messaging: Emergency SOS via satellite, matching the iPhone feature

What this means for health tech

Blood pressure monitoring on the wrist is one of the most requested health features in consumer tech. Hypertension affects 1.3 billion people globally and is often undiagnosed because regular monitoring is inconvenient. A reliable wrist-worn monitor could genuinely save lives by catching elevated blood pressure early.

The caveat is accuracy. Wrist-based blood pressure estimation is inherently less precise than arm-cuff measurements. Apple's conservative approach — trend monitoring rather than absolute readings — is medically prudent but may disappoint users who expect exact numbers.

Pricing and timeline

Expected pricing:

  • Apple Watch Series 11 (41mm): $399
  • Apple Watch Series 11 (45mm): $429

Launch alongside iPhone 17 in September 2026. The current Apple Watch Series 10 will likely drop to the $299 tier. For current watch comparisons, see our Apple Watch Series 10 vs Samsung Galaxy Watch 7 head-to-head.
