Pros:- Includes ECG and stress detection features
- Over 6 days of battery life
- Supports phone notifications and voice assistants

This hybrid watch offers a unique blend of classic analog aesthetics with digital health tracking, including ECG and AFib detection. Its standout feature is an impressive 35-day battery life, far surpassing most smartwatches like Fitbit Sense 2 or Samsung Galaxy Watch 4. While it doesn’t support full app customization or advanced smartwatch features, its stylish design and durable build make it ideal for those who prefer a traditional look with health monitoring.

Our verdict“The Withings ScanWatch 2 appeals to those valuing style and longevity over extensive smart features, with reliable health monitoring including ECG.”
KardiaMobile 6L EKG, No Membership Required, Unlimited Recordings, HSA/FSA
Unlike smartwatches, the KardiaMobile 6L offers clinical-grade, six-lead ECG results in just 30 seconds, making it ideal for users managing specific heart conditions. It provides highly accurate, FDA-cleared heart rhythm analysis for arrhythmias like AFib, Bradycardia, and Tachycardia.

Our verdict“This device is ideal for users needing precise, repeatable heart rhythm data, but not for general fitness or casual health tracking.”
Advanced Health Smartwatch for Women and Men with Real-Time Health Monitoring and Customizable Dials
This versatile smartwatch offers a broad suite of health metrics, including heart rate, blood oxygen, body temperature, and blood pressure, along with real-time stress and sleep monitoring. Its support for over 150 sports modes makes it suitable for fitness enthusiasts who want more than just ECG. Compared with dedicated devices like the KardiaMobile 6L, this watch provides a more comprehensive health picture but sacrifices some accuracy and specialized features for convenience and customization. Its large display, Bluetooth calls, and customizable interfaces make it a practical daily device for tech-savvy users.
Pros:- Supports extensive health measurements including ECG, blood pressure, and body temperature
- Over 150 sports modes for versatile activity tracking

Apple Watch Series 11 GPS 46mm Smartwatch with Jet Black Aluminum Case and Black Sport Band
The Apple Watch Series 11 stands out for its comprehensive health monitoring, including ECG, sleep scoring, and hypertension alerts, making it a top choice for those who prioritize detailed health insights. Its durable, water-resistant design and bright always-on display enhance daily usability, especially for water activities. Compared with the Fitbit Charge 6, it offers more advanced health tracking, but this comes with a higher price tag and a requirement for an iPhone to unlock all features. The quick charging capability and lightweight build support all-day wear, yet the 24-hour battery life can be limiting for users needing longer endurance.

How We Picked
These watches were evaluated based on their ECG accuracy, ease of use, build quality, battery life, and overall value. Devices with proven clinical-grade ECG capabilities and user-friendly interfaces ranked higher, especially those that integrate seamlessly with health apps. We also considered versatility—whether the watch offers multiple health metrics—and durability for everyday wear. Cost was factored in, but priority was given to products that deliver reliable, real-time ECG monitoring without unnecessary complexity. The ranking reflects the best balance of performance, usability, and value for different types of buyers.Factors to Consider When Choosing Watches With Ecg
Choosing the right watch with ECG involves weighing several key factors. Beyond just accuracy, consider how easy the device is to operate daily, its battery life, and whether it offers additional health metrics that matter to you. Build quality and comfort are also important, especially if you plan to wear the watch constantly. Price can vary widely, so understanding what features you need versus what you can do without helps avoid overspending. Finally, compatibility with your smartphone ecosystem and app ecosystem can enhance your overall experience.ECG Accuracy and Reliability
Ensuring the ECG feature provides accurate readings is vital, especially if you rely on it for health monitoring. Some watches have FDA-cleared or clinically validated ECG functions, making them more trustworthy for detecting irregular heart rhythms. Be wary of models that offer ECG as a secondary feature without proven accuracy, as false positives or negatives can cause unnecessary worry or missed alerts. Prioritize devices with a track record of reliable ECG performance, especially if you need it for medical reasons.
Ease of Use and App Integration
If you plan to use ECG regularly, the device should be simple to operate—quick measurements, clear instructions, and accessible results matter. Seamless app integration enhances this experience, providing detailed insights and easy sharing with healthcare providers if needed. Some watches automate ECG prompts or store history for trend analysis, making ongoing monitoring more manageable. Avoid overly complicated interfaces that can discourage regular use or lead to user errors.
Battery Life and Wearability
Battery life varies considerably across these devices, with some needing daily charging and others lasting a week or more. Longer battery life reduces the hassle of frequent charging, especially if you wear the watch continuously. Comfort and style also influence wearability—discreet, lightweight designs tend to encourage constant use, which is essential for consistent health tracking. Remember, high-tech features often drain battery faster, so balance your expectations accordingly.
Additional Health Features and Compatibility
Many watches combine ECG with other health metrics like SpO2, skin temperature, sleep tracking, and heart rate variability. Consider which metrics are most important for your health goals. Compatibility with your smartphone and health apps can also influence your choice, ensuring data syncs smoothly and provides comprehensive insights. Some models integrate with broader health ecosystems, which may be worth the extra investment if holistic health management is your goal.
Price and Long-term Value
Premium devices tend to offer superior build quality, more accurate ECG sensors, and extra features, but they come at a higher cost. Budget-friendly options often cover the essentials but may lack some accuracy or durability. Think about your long-term needs—investing in a more capable device could be worthwhile if you depend on ECG data for ongoing health management. Conversely, casual users might prefer simpler, more affordable models that meet basic needs without overspending.
Frequently Asked Questions
Can I rely on smartwatch ECG readings for medical diagnosis?
While many smartwatches now include clinically validated ECG features, they are not a substitute for professional medical diagnosis. These devices can detect irregularities like atrial fibrillation, but false positives and negatives are possible. If you experience symptoms or receive abnormal readings, consult a healthcare professional for a comprehensive assessment. Regular use of ECG on your smartwatch can be a helpful screening tool, but it should complement, not replace, professional care.
How accurate are smartwatch ECGs compared to medical-grade equipment?
Smartwatch ECGs have improved significantly and can offer reasonably accurate readings for detecting common arrhythmias. However, they generally do not match the precision of clinical-grade ECG machines used in medical settings. Factors like sensor placement, motion, and user technique can influence accuracy. For everyday health monitoring and early alerts, they are effective, but confirmatory testing by a healthcare provider is recommended if abnormalities are suspected.
Will my smartwatch’s ECG work with my phone or health app?
Most modern watches with ECG are designed to sync seamlessly with their respective apps, whether on Android or iOS. Compatibility ensures you can view, track, and analyze your data easily. Check the specific device specifications to confirm compatibility with your phone’s operating system and whether additional apps are required. Some devices also support exporting data for sharing with healthcare providers, which can be valuable for ongoing health management.
Are there any ongoing costs associated with using ECG features on smartwatches?
Most watches include ECG functionality as part of the initial purchase, with no recurring fees. However, some advanced features or detailed health analysis might require a subscription or app upgrade. Additionally, if the device is part of a broader health ecosystem, there may be costs for premium app features or cloud storage. Always review the terms before purchasing to understand any potential ongoing expenses.
What should I consider if I want a watch with ECG for everyday fitness tracking?
For daily use, prioritize a device with a comfortable design, long battery life, and easy-to-understand ECG results. While accuracy is important, practicality and integration with your existing health routines matter more for regular fitness tracking. Models that combine ECG with other metrics like heart rate, sleep, and activity tracking can provide comprehensive insights without overwhelming you with complexity. Balance cost with features to find a device suited for continuous wear and health awareness.
Conclusion
For those seeking the best overall performance, the Fitbit Sense 2 offers a reliable combination of ECG accuracy and broad health features, making it ideal for health-conscious users. Budget-conscious buyers will find the Samsung Galaxy Watch 4 provides solid ECG capabilities at a lower price point. If premium build quality and advanced features matter, the Withings ScanWatch 2 stands out as a sophisticated hybrid option. Beginners or casual users should consider simpler models with easy interfaces, while those with specific health concerns might prioritize FDA-cleared devices. Matching your needs with the right features will help you make the most of your watch with ECG capabilities.
