Review: Withings BPM Vision

When you visit your doctor’s office, a blood pressure test is often the first thing you'll face. Blood pressure measures how hard your blood pushes against your artery walls as your heart beats, and it’s one of the most important vital signs. High blood pressure means an increased risk of heart failure, heart attack, or stroke, which are among the leading causes of death in the US, and nearly half of the adults in the country have high blood pressure.

Hypertension is one of the easiest, widespread health problems to solve because we have all the tools, and the fixes are relatively easy, if not always simple to scale: Eat less salt. Drink less alcohol. Exercise more. Still, it remains hard to monitor blood pressure at home because you need an arm cuff. You still can’t get a blood pressure reading from a fitness tracker, although Apple has been developing one for the Apple Watch. Samsung has rudimentary support for blood pressure monitoring on its Galaxy Watch, but the feature isn't available in the US and has caveats.

Enter: Withings’ BPM Vision, the update to the no-frills BPM Connect ($100). Withings also launched Cardio Check-Up this year, a service within the Withings+ subscription that lets you send information on your cardiac health to a certified board of cardiologists for review. It is easier than ever not to let a heart attack sneak up on you.

The BPM Vision is a tabletop unit, which makes it easier to use and see the display in contrast to the BPM Connect, which has all the electronics in the cuff. This is important for a blood pressure monitor because everything affects your blood pressure, including whether your legs are crossed and if you’re sitting up or leaning back. The BPM Connect wasn’t difficult to use, but it’s infinitely easier to unzip the BPM Vision at my dining room table, lean back, and relax for five minutes.

It also charges via USB-C, and both my spouse and I have been using it for a few weeks with no sign that the battery is low. It’s a little annoying that there’s no battery indicator, but again, this matters less for a tabletop unit you can plug in while using it than for a cuff. It comes with one regular-sized cuff with a range from 8.7 inches to 16.5 inches that comfortably fits both my husband’s and my arms (my arm is 9 inches around and his is 15). You can also order an XL cuff for arms bigger than 15.8 inches.

It’s FDA-cleared and meets the validation protocols recognized by organizations such as the Association for the Advancement of Medical Instrumentation and the American Heart Association. It is hard for me to independently verify its accuracy, given that I’m not a physician, but the heart rate readings are the same when checked against a Whoop Band and an Oura Ring.

It was easy to set up—just turn it on and connect it to the Withings app. You can see your readings simultaneously on the LCD and the Withings app on your phone, which is compatible with iOS and Android. (It also syncs with Apple Health, Samsung Health, and a few other apps.) You can also have someone else use it as a guest profile, although their readings will not be saved.

You can subscribe to Withings+ with one month free, and then it's $100 per year or $10 per month. If you’re worried enough about hypertension that you want to monitor your blood pressure at home, I think you probably already know what you need to do to improve your health, and the Withings+ Health Improvement Score won’t help you.

You Need to Calm Down

I asked Jehan Bahrainwala, a Stanford professor with a clinical area of focus in resistant hypertension and secondary hypertension, how you’re supposed to use this thing. “It is more useful to have more readings over a short time period than sporadic readings over a longer time period,” she responded over email. “I recommend patients monitor their blood pressure at the same time daily for one week in a row, one week per month, and keep a journal of these readings.”

The display is simple—it shows your systolic and diastolic blood pressure and heart rate. You can take one measurement at a time or three in a row, which takes about 5 minutes with 45 seconds of rest in between. I recommend taking three in a row because even if you follow every other instruction that Withings gives you, my first reading always showed elevated blood pressure.

It turns out that taking your own blood pressure reading isn’t as easy as lying on an exam table. To use the BPM Vision, I sat down at my kitchen table at the same time every morning. I had my back supported, with my feet uncrossed and flat on the floor. I took my sweatshirt off and drank plenty of water. I rested my arm on the table for around 5 minutes, then I wrapped the cuff around my upper arm with the tube running down the middle, along my vein.

I have a family history of stroke, so I have a particular interest in monitoring my blood pressure. It’s worth noting here that I am scrupulously healthy, as befits someone covered in fitness trackers at all times. I watch what I eat; I exercise regularly; I avoid alcohol. However, I can make my blood pressure shoot up by thinking about the wrong person at the wrong time. (If you’re reading this, it’s not you!)

However, my husband has no history of high blood pressure or high cholesterol, and he doesn’t have to follow any rules whatsoever. He can take a reading immediately after an hour-long hike with the dog, and his blood pressure will be low. With blood pressure readings, as with so many other things, your mileage will vary. Neither of us found it uncomfortable when the cuff was inflated.

Given that one of the main selling points of a Withings+ subscription is Cardio Check-Up, it’s a major ding that this feature does not work with the BPM Vision. (Cardio Check-Up only works with Withings products that have the ECG feature, like the Scanwatch 2.) You can download a comprehensive monthly health report on the Withings app to bring to your health care provider, and it includes your blood pressure readings, but it’s not the same level of concierge service as having a cardiologist check on you within 24 hours.

The BPM Vision is also bigger than the BPM Connect, a factor to contend with if you plan on traveling with it (and if you have to take your blood pressure every day, you probably will). But do you need a blood pressure monitor? Unfortunately, you should probably have one, even if you don't have a family history of stroke. “High blood pressure is very often asymptomatic," says Bahrainwala. "Home blood pressure monitoring could help diagnose this earlier, which can then lead to timely interventions.”

The Withings BPM Vision is handy and comfortable, and you don't have to wear a giant, clunky thing on your arm. Even if you can’t send the data to a cardiologist to check ASAP, it’s particularly useful that you can easily keep a long-term journal in the app to give to a provider. I—and you, too, probably—should make sure to get a little more time to exercise from now on.
