Study Watch with Irregular Pulse Monitor (Home)
Overview
The Verily Study Watch with Irregular Pulse Monitor (Home) is a prescription-only wearable device developed by Verily Life Sciences, an Alphabet Inc. company, for use in clinical research and by healthcare professionals. It is designed to unobtrusively collect a wide range of physiological data from participants in real-world settings.
Initially launched as an investigational device in April 2017, the Study Watch has evolved to include advanced monitoring capabilities. It features multiple physiological sensors, such as an on-demand single-channel electrocardiogram (ECG), heart rate tracking, electrodermal activity, and inertial movement sensors. Environmental sensors are also integrated. The device boasts a long battery life of up to one week and substantial internal storage for raw data, which is encrypted on the device for security. Collected data is then uploaded and processed in the cloud using Verily’s proprietary algorithms and machine learning tools.
The Study Watch is not available directly to consumers but is utilized in various clinical studies and by healthcare professionals for specific patient monitoring, particularly in cardiovascular health, neurological conditions, and sleep research.

What Physicians Need to Know
The Verily Study Watch, a prescription-only device, provides valuable clinical-grade data for monitoring irregular heart rhythms, particularly atrial fibrillation, and can contribute to early identification of heart failure risk through activity monitoring. Its on-demand single-lead ECG and continuous photoplethysmography (PPG) capabilities offer a robust tool for long-term surveillance and burden assessment of AFib. Physicians should leverage the secure cloud data transfer and integration with platforms like iRhythm's Zio Service for comprehensive patient management. While it aids in screening and monitoring, definitive diagnosis and treatment decisions should always be based on a full clinical evaluation.
The Verily Study Watch integrates with Verily's secure cloud infrastructure for data storage and access by healthcare professionals. It has a notable collaboration with iRhythm Technologies, leveraging iRhythm's Zio Service for advanced AFib data analytics and cloud-based machine learning. Additionally, Verily is expanding its integration capabilities through a collaboration with Samsung, aiming to incorporate sensor data from Galaxy Watch devices into its Viewpoint Evidence solution, built on the Verily Pre platform, to accelerate clinical research and generate real-world evidence.

What the Web Says
The Verily Study Watch with Irregular Pulse Monitor (Home) is a prescription-only, clinical-grade wearable designed for adult patients (22 years and older) who have been diagnosed with, or are susceptible to developing, atrial fibrillation (AFib). It continuously monitors heart rhythm using photoplethysmography (PPG) and prompts users to take a single-lead ECG if an irregular pulse is suspected. The device is intended for use in professional healthcare settings and clinical studies, not for direct consumer purchase.
Overall: PositiveStrengths
- Clinical-grade accuracy for AFib detection, with high sensitivity and specificity.
- Continuously monitors heart rhythm in a free-living (home use) setting.
- Integrates with healthcare providers through a cloud-based data network.
- Aims to reduce false positives seen with consumer-grade smartwatches.
- Long battery life (week-long) compared to many consumer smartwatches.
- Can record, store, transfer, and display single-channel ECG rhythms.
Limitations
- Not available for direct purchase by consumers; prescription-only and intended for clinical use.
- Performance may decrease for some AFib episodes in participants with darker skin tones, although still able to detect AFib.
- Limited information available from independent tech reviewers, Reddit, G2, or Capterra due to its clinical focus and restricted availability.
- Some consumer smartwatches have shown inaccuracies in detecting AFib.
