Withings BPM Connect Review: Accurate, Hands-Off, and Right for Some Older Adults

What the BPM Connect is, and what it is not

The BPM Connect is an automatic upper-arm blood pressure monitor built into a small cylinder, about six inches long, that is joined to its cuff. You wrap the cuff around the bare upper arm, rest the arm on a table, and press the single button. It inflates, measures, and shows the systolic and diastolic pressure and the heart rate on a small LED dot-matrix screen, with a coloured light that shows at a glance whether the reading is in the normal or high range.

What makes it different from most home monitors is what happens after the reading. It connects to home Wi-Fi as well as Bluetooth, so readings upload to the Withings app by themselves, even if the phone is in another room or another town. The device holds up to eight readings if it cannot connect, then sends them on next time it can.

It is not an ECG device, and Withings lists only blood pressure and heart rate among the things it measures, with no irregular-heartbeat or atrial fibrillation (AFib) flag. It is also not a cellular device: a version called the BPM Connect Pro, made for doctors' remote-monitoring programmes, sends readings over the mobile network without home Wi-Fi.

Is the Withings BPM Connect accurate?

Yes, when it is used properly. Accuracy is the one thing a blood pressure monitor cannot get wrong, and it is the first thing to check. The BPM Connect (model WPM05) is on the Validated Device Listing run by the American Medical Association, which only includes monitors validated for clinical accuracy. Its listing names the ANSI/AAMI/ISO 81060-2 standard, an arm range of 22 to 42 cm, and validation for adults in general and in pregnancy.

The published validation study, in the journal *Vascular Health and Risk Management* in 2022, tested it against the international standard in 85 people. On average its readings differed from reference measurements by 0.6 mmHg systolic and 2.1 mmHg diastolic, well inside the standard's limit of 5 mmHg, and it passed every criterion of the standard. The study was in the general population rather than specifically in older adults.

Two cautions. Withings says readings may be inconclusive for anyone with a pacemaker or an implanted cardioverter defibrillator. And no monitor is more accurate than the way it is used: a cuff on top of a sleeve, a reading taken straight after walking upstairs, or an arm hanging by the side can each push the numbers up by more than any difference between good monitors.

What it is like for an older adult to use

Day to day, it is simple: cuff on, arm on the table, one press of the button. There is nothing to plug in, and no tube to connect, because the cuff and the monitor are one piece. The battery is rechargeable, and Withings says a charge lasts about six months, with the battery level shown in the app, so there are no small batteries to find and change.

Three things are harder than they need to be for an older user:

• Setup. Installing it requires the Withings app on a smartphone (iOS 18 or Android 12 and later) and the home Wi-Fi password. It cannot be set up from a computer. In practice, a family member or carer will usually do this once.
• The display. The reading appears on a small LED dot-matrix screen on the end of the cylinder. It is bright, but the figures are much smaller than the large digits on many simpler monitors. The coloured light helps: green for normal readings, orange for high-normal and red for high blood pressure, according to Withings.
• More than one user. Up to eight people can use one monitor, but after each reading you have to cycle through the names with the single button and hold it to assign the reading. That is easy to get wrong, so a couple sharing one monitor should practise it together.

If the person being measured lives alone and will not ask for help with the setup, that is a reason to choose a simpler monitor rather than a reason to struggle with this one.

Sharing readings with family and the doctor

This is the reason to buy a BPM Connect. Once set up, readings arrive in the Withings app by themselves, so a family member can see whether a parent is measuring and what the numbers are, without phoning to ask. Withings says the app can securely share data, produce a PDF report to send to a doctor, and show a live dashboard during a video appointment.

That matters most when a doctor is adjusting blood pressure medication and has asked for home readings. A complete record of every reading, with times, is more useful than a handwritten list with gaps, and more honest than one where the high readings were left out.

Remember that the doctor will not see the readings unless someone shares them. Agree in advance how the readings will reach the surgery: a PDF before each appointment, or whatever their own system accepts.

The 3-reading mode

Single readings vary, which is why the American Heart Association advises taking two readings a minute apart and recording both. The BPM Connect has an automatic mode that takes three readings in a row and shows only their average. To use it, press the button to switch it on, then press and hold until the screen shows BP x3, and press again to start. The gap between readings is set in the app.

Withings says that, because of an FDA requirement, this mode has to be selected each time it is used. For an older adult that is one more step to remember, but it is worth learning: an average of three readings is a better guide to treatment than one.

How to take an accurate reading at home

These steps come from the American Heart Association, and they matter as much as the monitor:

• No caffeine, smoking or exercise for 30 minutes before, and empty the bladder first
• Sit in a dining chair rather than a sofa, back supported, feet flat and legs uncrossed
• Rest quietly for five minutes, without talking or looking at a phone
• Put the cuff on the bare upper arm, never over a sleeve
• Rest the arm on a table so the cuff is at heart level
• Take two readings a minute apart (or use the BPM Connect's 3-reading mode), at the same times each day
• Have the monitor checked against the equipment at the doctor's office, typically once a year

The AHA also gives the reading to act on: higher than 180 systolic and/or 120 diastolic is a hypertensive crisis. Wait a few minutes and measure again, and if it is still that high, contact a doctor straight away. If it comes with chest pain, breathlessness, weakness, numbness, vision changes or difficulty speaking, call 911.

Check the arm size before buying

A cuff that is the wrong size gives the wrong reading, and the BPM Connect has one cuff, built in. It fits upper arms from 22 to 42 cm (about 9 to 17 inches) around, measured midway between the shoulder and the elbow. That covers most adults, but not everyone, and there is no larger cuff for this model.

For an arm larger than 17 inches, choose a monitor with a larger cuff. Withings sells an XL cuff (40 to 52 cm) for its BPM Vision, and the Greater Goods XL-cuff monitor is listed for arms from 15.7 to 20.5 inches. Our roundup covers more options.

BPM Connect vs BPM Vision and Omron

The closest alternatives are Withings' own BPM Vision, which adds a larger screen, and Omron's Bluetooth monitors, which are cheaper and include a heartbeat check. All of these figures come from the makers' Amazon listings and, for the two Withings models, Withings' own comparison page.

Who should buy it

Choose the BPM Connect when the readings need to reach someone else: an adult child keeping an eye on a parent's blood pressure from a distance, or a doctor who has asked for home readings while adjusting medication. Its validated accuracy and hands-off Wi-Fi upload do that better than monitors that rely on a Bluetooth phone app being opened.

Choose the BPM Vision instead if you want the same automatic syncing with a larger, clearer screen and on-device instructions. Choose an Omron such as the Platinum if an AFib check matters, or because the person is used to AA batteries and a bigger display. And if nobody will ever look at the readings except the person taking them, a simple validated monitor with large digits is the better buy.
