Expert Review Summary

Our clinical assessment and verdict for each device

Withings BeamO

Highly Recommended

"A revolutionary handheld health station that bridges the gap between basic vital tracking and professional clinical assessment at home[cite: 13, 69]."

The Withings BeamO, referred to as a 'multiscope,' is a multifunctional medical device designed for comprehensive at-home health checkups[cite: 1, 13]. It integrates four critical clinical tools: a 1-lead ECG, a pulse oximeter (SpO2), a contactless temporal artery thermometer, and a digital stethoscope[cite: 13, 20, 21]. The device is engineered to provide an overview of multiple physiological conditions, facilitating increased awareness of a patient's health status and providing trends over time that can be shared with healthcare professionals[cite: 68, 69]. The BeamO is particularly notable for its connectivity options, supporting Wi-Fi, Bluetooth, and optional LTE (Cat M1) for data synchronization even when a smartphone is not nearby[cite: 11, 208, 347]. Clinical validation has been established for its temperature measurement accuracy through studies conforming to EN ISO 80601-2-56 standards[cite: 70]. While the ECG and SpO2 features are restricted to adult use (18+), the thermometer and stethoscope are indicated for use on individuals of all ages[cite: 14, 15, 31, 216]. The device emphasizes security with features like two-factor authentication and encrypted data sharing through HealthLinks[cite: 78, 81, 105, 534].

Eko DUO (ECG + Stethoscope)

Highly Recommended

"The Eko DUO is an indispensable hybrid device for clinicians and high-risk patients, offering amplified heart sounds and synchronized ECG data in a single, streamlined interface."

The Eko DUO (ECG + Stethoscope) represents a significant advancement in bedside diagnostic technology. It combines a 1-lead ECG with a high-fidelity digital stethoscope, allowing for the simultaneous assessment of electrical and mechanical heart function. The device provides up to 60x sound amplification and features advanced background noise reduction, which is critical for identifying subtle murmurs or gallops in loud clinical environments. The integrated ECG electrodes capture a Lead I rhythm strip that is transmitted via Bluetooth to the Eko App for real-time visualization and analysis. The DUO is specifically designed to work with Eko's FDA-cleared AI algorithms, which can screen for Atrial Fibrillation and heart murmurs with high sensitivity. While it is a single-lead device, the correlation between the acoustic and electrical data provides a depth of insight typically only found in much larger clinical systems. Its wireless charging capability and pocket-sized form factor make it highly practical for daily rounds or home-based monitoring under medical supervision.
