Your blood pressure is an important biometric that gives you vital information about what’s going on inside your body. Even if you don’t have diagnosed hypertension or a family history of high blood pressure, it’s important to keep an eye on your blood pressure numbers, especially as you age or if you are pregnant.

Undiagnosed and untreated high blood pressure can lead to a host of health complications, from optic nerve damage to heart disease. When you know what your blood pressure is, you and your doctor can have a better idea of whether you need to adjust medications, diet, exercise, or other activities.

Since blood pressure can fluctuate throughout the day, it’s best to be able to take readings often. But in the past, most people were limited to only getting an accurate blood pressure reading at a doctor’s office. Consumer-friendly blood pressure cuffs can be more convenient because you can use them at home, but you may not be able to wear them all the time because they are bulky and uncomfortable.

Enter: the wearable device. Blood pressure monitor watches and fitness trackers give you the freedom to take measurements as often as you choose to, even on the go. Some of these devices also count steps or monitor sleep patterns. There are also wrist blood pressure monitors that don’t resemble watches. These devices are larger and designed primarily for at-home use.

Here are a few tips to consider when looking at watches designed to keep up with your blood pressure.

According to the American Heart Association, upper arm cuff-style blood pressure monitors provide more accurate readings than wrist or finger monitors. One reason for this is that when you take a blood pressure reading, the monitor must be at heart level, with the upper arm resting near the heart.

To match the readings provided by upper arm blood pressure monitors, some watches include instructions to keep your wrist on your heart during readings. Following these instructions helps to ensure you’ll get the most accurate reading possible.

A good way to test your watch’s accuracy is to compare its readings with those received in a medical setting. You can do this by taking your watch with you to a doctor’s appointment and testing yourself immediately after getting an upper arm cuff reading.

We chose the blood pressure monitor watches on this list because users indicate they provide accurate or near-accurate results. They come from transparent manufacturers who don’t make unfounded claims. We read scores of consumer reviews on multiple websites and researched each company’s background and reputation.

  • $$ = $50-$400
  • $$$ = over $400

Most accurate blood pressure watch

Omron HeartGuide

  • Price: $$$
  • Battery life: 2 days per charge
  • Waterproof: no

This FDA-cleared medical device uses an inflatable cuff inside the watchband that you activate when you want to take your blood pressure. Readings take around 30 seconds.

It syncs up to a companion app called HeartAdvisor, which provides information about your readings. The app collects and stores your data in the form of color-coded graphs that help you see trends in your readings, based on variables such as exercise and time of day. The HeartAdvisor app is available for both Android and Apple devices.

Pros: Readings are quick and accurate, and the watch has lots of amenities besides blood pressure. It also helps you track and monitor fitness goals and sleep patterns. The display is simple to read, even if you are farsighted. The watch can send notifications when you receive texts and emails, and an extended warranty is available from the manufacturer to protect your purchase.

Cons: Some reviewers say that this watch is bulky and uncomfortable to wear. It’s also important that you get the right size for your wrist. People with slim wrists might find this watch heavy. The biggest con of all might be the price, which is the highest on our list. Even though it’s incredibly expensive, the watch does not appear to be waterproof.

FitVII Smartwatch

  • Price: $$
  • Battery life: 3 to 10 days
  • Waterproof: yes

This fitness and sleep tracker takes blood pressure and heart rate readings, which are stored in a companion app. In online reviews, some users say it’s remarkably reliable, especially for an inexpensive watch.

Pros: It includes a heart rate alarm feature and a fatigue test. Other interesting features include an alert system that tells you to stand up when you’ve been sitting for too long. Even though this watch is priced for a smaller budget, it’s waterproof. You can choose from several different color bands according to your preference. No wires are required to charge on the wireless charging station.

Cons: This watch isn’t the most stylish of the bunch, and no one is going to mistake it for a regular watch. The display is meant to be easy to read, but the screen is a bit small. There doesn’t seem to be any warranty available for this watch, though you can purchase a replacement strap if it breaks.

Best blood pressure watch on a small budget

MorePro Activity Tracker

  • Price: $
  • Battery life: 5 days
  • Waterproof: some water resistance

This activity tracker is compatible with Android and Apple phones. It also comes with an app that you can use to track your vitals and activity levels every day, just like more expensive fitness trackers.

Pros: For an activity tracker that’s on the lowest end of the price spectrum, this device really does have a lot to offer. It has built-in GPS, a pedometer, blood oxygen level readings, an app to track it all, and of course, blood pressure measurement. It isn’t big or bulky, so you can easily sleep while you’re wearing it and get information about your sleep quality in the morning. There’s even a 180-day warranty.

Cons: The MorePro Activity Tracker isn’t a medical device, so it’s not subject to FDA approval to back up its claims. This is more of a device for tracking your overall health, not necessarily the best or most accurate blood pressure measurement that you can get. The display is quite small, so it won’t be easy for everyone to read.

If you’re in the market for a wearable device that tells you your blood pressure, you’ll need to establish the key features that are important to you before you start to shop.

First, you’ll need to decide whether you’re looking for a wearable blood pressure monitor that happens to tell time, or if what you want is a fitness tracker that supplies blood pressure readings. If you want a wearable blood pressure monitor, you may want to purchase one of the devices the FDA has approved. Fitness trackers aren’t currently subject to any FDA oversight.

Next, consider how the device will need to fit in with your lifestyle. Some devices are so waterproof that you can wear them while swimming, while others can’t even be on the bathroom counter while you run a steamy shower. Also, become acquainted with how long the battery life lasts on your preferred device, since some need to be charged quite often.

The display of the device you use makes a difference. Ask yourself:

  • Is the design intuitive?
  • Will you be able to read the screen easily?
  • Do you feel like you can navigate the menu of the device to maximize its value and use all of its features?

Some blood pressure watches and fitness trackers sync to both Apple and Android devices, but others do not. Check the compatibility of your preferred device before you buy.

Pricing varies widely, so look around to make sure that you’re buying something you can afford. Some products don’t have a lot of up-front costs but may require you to pay for a monthly service plan to keep the device active.

Finally, make sure that your purchase is protected. When choosing from the many options available, look for manufacturers that offer at least a 1-year warranty, plus free returns or exchanges within 30 days.

It’s hard to know. The best way to check is to compare several readings with a medical-grade device.

Available research

Large-scale testing for accuracy hasn’t been done on blood pressure monitor watches or on fitness trackers that contain a blood pressure reading feature.

A few small studies have looked at the accuracy of specific watch models, with uneven results. A 2020 study showed positive results, but it was funded by a watch manufacturer. Another 2020 study showed negative results and had researchers with stated conflicts of interest.

FDA clearance vs. FDA approval

Some blood pressure monitor watches are marketed as FDA-cleared medical devices. FDA clearance isn’t the same thing as FDA approval.

Unlike class III medical devices that support or sustain life, wrist monitors are categorized as class I or class II low risk medical devices. Low risk medical devices don’t require FDA approval to be marketed. The FDA doesn’t guarantee the results of the watch you buy.

However, these watches still have benefits. They may give accurate or near-accurate results that provide valuable information — for example, if you have high blood pressure during pregnancy. They may also provide information about how your blood pressure responds to exercise.

Just don’t rely on watches as your sole blood pressure monitoring device. This may be especially important if you have hypertension (high blood pressure) or take medications that make you prone to hypotension (low blood pressure).

Blood pressure monitor watches may provide accurate readings, although this hasn’t been proven in large-scale studies.

To get the most accurate, consistent results, it may make sense to choose a watch designed specifically for this purpose, rather than a fitness tracker that includes this feature.

Blood pressure monitor watches may have benefits for people who wish to test their readings several times a day.

Fitness trackers with this feature may have value for people who wish to track their blood pressure and heart rate before and after exercising.

If you have a health condition such as hypertension, don’t rely on wrist monitors exclusively for your readings. No watch takes the place of monitoring by a healthcare professional.
