Withings BPM Core Review: BP Monitor with ECG and Digital Stethoscope
The Withings BPM Core is the only home blood pressure monitor with a built-in single-lead ECG and a digital stethoscope. It is FDA-cleared, clinically validated to AAMI/ESH ±3 mmHg for blood pressure, and the ECG is cleared for atrial fibrillation screening. At $249.95, it costs more than a standard validated monitor, but for people with AFib, suspected AFib, or heart valve concerns, the extra screening tools are worth it.

What We Like
- + FDA-cleared single-lead ECG. Records 30 seconds and screens for atrial fibrillation.
- + Digital stethoscope captures heart valve sounds. Useful for people with known valvular disease.
- + Blood pressure accuracy validated to AAMI/ESH ±3 mmHg.
- + Wi-Fi sync. No phone needed during measurement.
- + Long battery life (~6 months per charge) with USB-C.
- + Cloud sync to Withings Health Mate app, Apple Health, and Google Fit.
- + On-device color display shows BP category right away.
- + PDF export for sharing with your doctor or cardiologist.
What We Do Not Like
- − Costs $250 versus $99 for the BPM Connect with same BP accuracy.
- − ECG is single-lead. Misses some arrhythmias a 12-lead ECG would catch.
- − Stethoscope analysis feature is not FDA-cleared in the US, just heart-sound recording.
- − Withings account required to use the app.
- − No multi-user profiles on the device itself.
BPM Core vs BPM Connect: Which Should You Buy?
The blood pressure accuracy is identical between the two. Both are validated to AAMI/ESH ±3 mmHg. The difference is the ECG and stethoscope on the Core.
Pick the Withings BPM Connect at $99 if you only need a validated BP monitor with Wi-Fi sync.
Pick the BPM Core at $250 if you have AFib, suspected AFib, palpitations, or a personal or family history of valvular heart disease and want home screening tools your cardiologist can review.
Who Should Buy It
- • People with diagnosed atrial fibrillation who want to monitor BP and rhythm at home
- • Anyone with palpitations or suspected AFib who wants screening data before a cardiology visit
- • Patients with valvular heart disease who track heart sounds over time
- • People who want the strongest at-home cardiac screening package available
Who Should Skip It
- • Anyone who only needs BP tracking - buy the cheaper Withings BPM Connect at $99
- • Households with multiple users - Core has no multi-user profiles
- • Patients who already wear an Apple Watch or Fitbit with ECG and just need BP

Frequently Asked Questions
What does the Withings BPM Core do that other monitors do not?
Three things in one device. It takes an upper arm blood pressure reading like any validated monitor. It records a 30-second single-lead ECG that screens for atrial fibrillation. And it captures a digital stethoscope recording of your heart valves that the Withings Health Mate app analyzes for early signs of valvular disease.
Is the Withings BPM Core FDA-cleared?
Yes. The blood pressure function is FDA-cleared and clinically validated to AAMI/ESH ±3 mmHg. The ECG function is FDA-cleared for atrial fibrillation detection. The digital stethoscope analysis is currently available outside the US but the heart-sound recording feature is enabled globally.
How accurate is the ECG on the Withings BPM Core?
The single-lead ECG has been studied against a 12-lead reference and is accurate for atrial fibrillation screening. It is not a diagnostic tool. If the device flags possible AFib, share the ECG strip with your cardiologist for confirmation.
Does the BPM Core need Wi-Fi to work?
No. The device works standalone and stores readings locally. Wi-Fi connection lets it sync readings to the Withings Health Mate app and to Apple Health and Google Fit without needing your phone nearby. You can also pair via Bluetooth.
How much does the Withings BPM Core cost?
The list price is $249.95 as of May 2026. It costs more than other home monitors because of the added ECG and stethoscope functions. If you only need a validated BP monitor, the Withings BPM Connect at $99 has the same blood pressure accuracy without the ECG and stethoscope.
Who should buy the BPM Core instead of a regular BP monitor?
Pick the BPM Core if you have hypertension plus atrial fibrillation, suspected AFib, or a personal or family history of heart valve issues. Most people without those conditions are better served by the cheaper Withings BPM Connect or Omron Platinum BP7350.
How long does the battery last?
About 6 months on a single charge for typical use. The device uses an internal rechargeable battery and a USB-C cable. The battery indicator in the Health Mate app shows current charge.
Does the BPM Core replace a cardiology workup?
No. The BPM Core is a screening tool, not a diagnostic one. AFib screening with a single-lead ECG misses some arrhythmias and can show false positives. Always discuss findings with your physician. A clinical 12-lead ECG and echocardiogram are the gold standards for diagnosis.
