Log your blood pressure in the Health app

You can log your blood pressure in the Health app to help monitor your hypertension or aid in assessing your hypertension risk with your doctor.

Here's what you need

Choose a blood pressure cuff

Automatic blood pressure cuffs that fit around your upper arm provide the most accurate measurements. Consult with your healthcare provider for personalized recommendations, but here's what to consider when purchasing a blood pressure cuff:

  • Choose a cuff that is an appropriate size for your upper arm. A cuff that is too small or too large will result in inaccurate readings. If your arm circumference is between sizes, it's generally better to choose a larger cuff.

  • Consider recommendations from relevant medical societies in your country or region.

  • Research brands known for producing reliable, health-focused products, and purchase your cuff from a pharmacy, medical supply store, or other reputable retailer.

If you're learning about your risk for hypertension, the log completes when you have a total of 7 wake-up and 7 bedtime measurements. If 7 wake-up and 7 bedtime measurements haven't been recorded after 6 months, the log closes automatically. If you're monitoring your hypertension, the log completes when you have one measurement each day for 28 days.

Depending on your location, or if you have an active pregnancy logged in the Health app, the Blood Pressure Log uses classifications from the following organizations for your average blood pressure measurements:

  • American Heart Association (AHA)

  • European Society of Cardiology (ESC)

  • International Federation of Gynecology and Obstetrics (FIGO)

The Blood Pressure Log is a separate feature, and logged blood pressure values do not influence the Hypertension Notification feature in any way. Once you've completed your log, you can tap Export PDF to share a PDF of your measurements with your doctor.
