Why this comparison

If you are over 50 and checking your blood pressure at home, two brand names come up constantly: Omron and Withings. They are not the same kind of company. Omron is a long-established maker of home health devices; Withings makes connected health gadgets built around a phone app. Our broader guide, best blood pressure monitor for home use after 50, covers what to look for in general. This page is narrower: it puts two specific, widely sold models side by side so you can decide between them. If you are still working out what your numbers mean, start with high blood pressure after 50.

We use the Omron BP5450 (sold as the Platinum, also named in some listings by the model number HEM-7343T-Z) and the Withings BPM Connect (model WPM05, also written WPM-05). Omron also sells the 10 Series BP7450, which Omron lists with the same two-user, 100-readings-per-user memory and the same 22 to 42 cm cuff range as the BP5450, so most of what follows about convenience applies to it as well. We did not find a published validation listing for the BP7450 in the sources we checked, so we do not make accuracy claims about it. Withings also sells other models with extra features; we do not cover them here.

What matters more than the brand: validation

Many home monitors sold online have never been independently tested. A study of best-selling monitors on Amazon found that only 16 percent of US upper-arm devices, and none of the wrist devices, had been validated. A device is “validated” when its accuracy has been checked against a reference method using a recognised protocol such as ANSI/AAMI/ISO 81060-2. The American Medical Association runs the free site validatebp.org, which lists devices that have passed. The American Heart Association recommends automated upper-arm monitors for home use and advises avoiding wrist and finger monitors, which tend to be less reliable. Always match the exact model number printed on the box to the listing, because related models have different numbers and validation does not automatically carry across.

What the sources say about these two

• Withings BPM Connect: validatebp.org has a listing for the BPM Connect (WPM05), with a 22 to 42 cm cuff range, tested against ANSI/AAMI/ISO 81060-2. A peer-reviewed accuracy study published in Vascular Health and Risk Management (2022) assessed it against the AAMI/ESH/ISO Universal Standard in the general population. A separate study in pregnancy and pre-eclampsia concluded the device met the protocol criteria for that group.
• Omron BP5450: validatebp.org has a Platinum upper-arm listing for adults with a 22 to 42 cm cuff, tied to the HEM-7311 designation and the ANSI/AAMI/ISO 81060-2:2009 standard. Medaval, an independent validation-rating site, notes that this listing relies on equivalence to the HEM-7311 rather than direct testing of the BP5450, and its page reports a validation study that did not meet a newer version of the protocol, with marginal diastolic results mentioned. Sources disagree on the model number (HEM-7311 versus HEM-7343T-Z), which is one more reason to check the exact label on the box. This is a nuance rather than a verdict: it does not mean the monitor is inaccurate, only that the evidence behind it is less direct than for the Withings.

Rating sites differ in how they judge devices, and we could not open every source in full, so look at the live validatebp.org and Medaval pages yourself before buying.

Who each suits

Omron BP5450 may suit you if

• You want a monitor that stores readings itself, and two people in the household can each keep their own record.
• You are fine pairing a phone through Bluetooth, or you plan to write readings in a notebook anyway.
• You prefer a device from a long-established home blood pressure maker with a wide set of models.
• You like seeing the previous reading next to the current one on the screen.

Withings BPM Connect may suit you if

• You want readings to land in the app automatically over Wi-Fi without using your phone each time.
• You want to share data with a family member or clinician through an app.
• You value the more direct published validation evidence.
• You are comfortable with a rechargeable device.

Downsides to weigh

Omron BP5450

• The evidence tying this exact model to a validation test is less direct, as noted above.
• Bluetooth pairing can be fiddly. One owner comment we saw said the manual was vague about syncing and that pairing failed when other Bluetooth devices were nearby. That is one person’s report, not a general finding.
• Some of the app’s features depend on having a smartphone.

Withings BPM Connect

• It relies on a Wi-Fi network and the Withings app, so it is less simple if you do not want an account or a phone app.
• It needs charging, so keep the cable handy.
• Our sources did not confirm on-device storage for two users, so check that if you share the monitor.
• Availability differs by region: the US model code is WPM-05, and some retailer pages describe other regional versions, so buy the version meant for your country.

How to get a reading you can trust

A good monitor still gives a poor number if the technique is off. These steps follow AHA home-measurement guidance as summarised in AHA materials:

1. Avoid smoking, caffeine and exercise for 30 minutes beforehand, and empty your bladder.
2. Sit quietly for at least five minutes with your back supported, feet flat and legs uncrossed.
3. Rest your arm on a table with the upper arm at heart level, and put the cuff on bare skin just above the bend of the elbow.
4. Do not talk or move during the reading.
5. Take at least two readings, about a minute apart, and record all of them.
6. Choose the right cuff: measure your upper-arm circumference. If it is outside the 22 to 42 cm range, neither of these cuffs will fit properly, and you need a different size.
7. Bring the monitor to a clinic visit about once a year and compare it with the office device.

Fluctuating readings are common. If you also notice a racing or irregular heartbeat, see our guide to heart palpitations after 50. Home readings do not replace medical visits, and you should not change prescribed treatment based on them without talking to your clinician. Seek urgent care for a very high reading with chest pain, shortness of breath, severe headache, vision changes, weakness or trouble speaking.

Where to look

Search results for the Omron BP5450 Platinum and the Withings BPM Connect show current listings. Check that the listing names the exact model and that the cuff range printed on it covers your arm. We have not confirmed which product pages are current, so these links lead to search results.

Our verdict

These two are closer than the brand names suggest: same cuff range, same upper-arm design, both with app syncing. The difference is how the data moves. If you want built-in memory and a simple Bluetooth app, the Omron fits. If you want automatic Wi-Fi syncing and the more direct validation record, the Withings fits. In both cases, the habits matter more than the logo: right cuff, same time of day, seated and rested, and a note of all readings for your clinician.

Frequently asked questions

Which is more accurate, Omron BP5450 or Withings BPM Connect?

We cannot rank accuracy from published sources. The Withings BPM Connect has a validatebp.org listing and peer-reviewed validation studies. The Omron BP5450 also has a validatebp.org listing, but Medaval notes it relies on equivalence to the HEM-7311. Check the exact model on validatebp.org and compare your monitor with your clinic’s device.

Do these monitors fit large arms?

Both list a cuff range of 22 to 42 cm (9 to 17 inches) of upper-arm circumference. If your arm is larger or smaller, you need a different cuff size, because a wrong-sized cuff gives inaccurate readings.

Is a wrist monitor a good alternative?

The AHA advises avoiding wrist and finger monitors for home use because they tend to be less reliable. A validated wrist device may be used in some situations, such as when no upper-arm cuff fits, but discuss that with your clinician.

Do I need a smartphone to use them?

Not to take a reading. Omron lists on-device memory for two users, and the Withings shows colour-coded feedback on the device. The apps add syncing, trends and sharing, and the Withings uses Wi-Fi to send readings to its app.

When should I worry about a home blood pressure reading?

One high reading is not a diagnosis; take another after resting and record all readings for your clinician. Seek urgent care if a very high reading comes with chest pain, shortness of breath, severe headache, vision changes, weakness or trouble speaking.
