Can your iWatch Monitor Blood Pressure?

As technology continues to advance, so does the capabilities of wearable devices. One of the most significant advancements in wearable technology in recent years is the ability to monitor our health in real-time. Apple’s iWatch is one such device that has gained tremendous popularity due to its many features, including monitoring vital signs such as heart rate, oxygen saturation, and activity levels. But does it have the ability to monitor another vital sign, blood pressure?

What is Blood Pressure?

Before delving into the question of whether the iWatch can monitor blood pressure, we must first understand what blood pressure is. Blood pressure is the force at which blood flows through our veins and arteries. It is measured in millimeters of mercury (mmHg) and is expressed as a ratio of systolic pressure, which is the highest pressure during a heartbeat, to diastolic pressure, which is the lowest pressure between beats.

What is the importance of monitoring blood pressure?

Given that blood pressure is a crucial indicator of our overall health, monitoring it is crucial in identifying and preventing heart-related diseases such as stroke, heart attacks, and kidney diseases. High blood pressure or hypertension, if left untreated, can lead to severe complications and even death. On the other hand, low blood pressure or hypotension can indicate underlying health conditions such as anemia, heart disease, or hormonal imbalances.

Can the iWatch Measure Blood Pressure?

The short answer is, No. Currently, the iWatch does not have the capability to monitor blood pressure. However, Apple has released its recent blood oxygen monitoring feature on the iWatch 6 and SE. This feature is similar to a pulse oximeter and can help users monitor their oxygen levels in real-time, a crucial indicator of overall health.

Why doesn’t the iWatch have the capability to Monitor Blood Pressure?

Apple has not yet incorporated blood pressure monitoring technology into its iWatch. The reasons are numerous, but one of the primary reasons is that monitoring blood pressure requires a sphygmomanometer, a device that measures blood pressure using an inflatable cuff placed around the arm. This device is cumbersome for wearable technology and may require significant modifications to the iWatch design to accommodate.

Alternative Ways to Monitor Blood Pressure

While the iWatch does not have the capability to monitor blood pressure, there are alternative methods available. These methods include:

  • Analog Sphygmomanometers: Traditional blood pressure monitors use an inflatable cuff and a manometer to measure blood pressure. While these devices can be cumbersome, they provide accurate readings and are readily available.
  • Digital Sphygmomanometers: Digital blood pressure monitors are more convenient than traditional analog monitors and are also more accurate. These devices use modern technology to measure blood pressure and can be linked to smartphones and other digital devices.
  • Smart Blood Pressure Monitors: These are wearable blood pressure monitors designed to provide real-time blood pressure readings. They are convenient and portable and can provide accurate readings when used correctly. Several designs are available, including blood pressure cuffs and wristbands.

Which alternative way is the most accurate?

The most accurate way to measure blood pressure is through an analog or digital sphygmomanometer. These devices are widely available and have been used for decades to accurately measure blood pressure. However, even with these devices, accuracy requires proper use and interpretation of results.

The Future of Blood Pressure Monitoring on iWatch

While Apple has not yet released a blood pressure monitoring feature on the iWatch, it is rumored that the company is working on developing the sensor technology required to monitor blood pressure. Future iWatch models may incorporate this technology, providing yet another vital sign to monitor in real-time.

How accurate will the iWatch monitor blood pressure?

This has yet to be determined. While the incorporation of blood pressure monitoring is exciting news, the accuracy of the readings will depend on the technology used by Apple. Sphygmomanometers provide extremely accurate measurements, and it remains to be seen if the iWatch can compete.


In conclusion, while the iWatch does not currently have the capability to monitor blood pressure, there are alternative methods available to do so. As technology continues to advance, it’s possible that future iWatch models may incorporate blood pressure monitoring technology, providing yet another convenient way to monitor our health.
