You cannot check blood pressure on iPhone 12 using the phone itself; the device requires a separate blood pressure cuff to take a measurement. The iPhone 12 works with Apple’s Health app to log and track readings, but it has no built-in sensor to measure your blood pressure directly.
Can you check blood pressure on iPhone 12?
No, the iPhone 12 does not measure blood pressure on its own. Apple’s support documentation confirms that blood pressure logging in the Health app requires a blood pressure cuff and an iPhone 11 or later with the latest iOS. The phone acts as a data hub, not a measurement tool.
How to log blood pressure in the Health app
Setting up the Blood Pressure Log in the Health app for the first time takes a few steps. Apple documents two tracking purposes you choose during setup:
- Open Health > Browse > Heart > Blood Pressure Log > Get Started.
- Follow the prompts to choose a purpose: Learn About My Risk for Hypertension (logs 7 days of morning and evening measurements for a doctor report) or Monitor My Hypertension (logs daily measurements for 4 weeks).
- Schedule reminders as prompted.
Once set up, the log automatically stores readings from a paired Bluetooth cuff or manual entries, making it easy to track trends without extra effort.
How to manually add a blood pressure reading
If you do not have a Bluetooth cuff or prefer to enter data by hand, the Health app lets you add a reading with the exact fields Apple requires:
- Open Health > Browse > Vitals > Blood Pressure > Add a Measurement.
- Enter the Date, Time, Systolic, and Diastolic values.
- Tap Add to save the entry.
This method is useful when you take a reading with a non-connected cuff and want to keep a complete record in one place.
Using a blood pressure monitor with your iPhone 12
Pairing a Bluetooth blood pressure cuff with your iPhone 12 is the most seamless way to track readings. Apple states that blood pressure monitors can store data in Health, and Bluetooth devices need to be paired with iPhone. Follow the device’s own setup instructions, companion apps are just an interface for the cuff, not a separate measurement system. Once paired, the cuff automatically sends readings to the Health app, eliminating manual entry and reducing errors. This integration is especially helpful when you are busy and want readings logged without navigating home screen and apps to type numbers. Note that the third-party app Blood Pressure: Health+ requires iOS 17.0 or later, which may affect iPhone 12 compatibility.
