HeartLab vs Samsung Health Monitor: ECG App Comparison
Samsung Health Monitor provides basic AFib screening on Galaxy Watch. HeartLab delivers advanced arrhythmia detection, comprehensive HRV analysis, and professional medical reports from Apple Watch ECG.
Feature Comparison
HeartLab and Samsung Health Monitor take different approaches to ECG analysis. Samsung Health Monitor is a built-in Galaxy Watch app that provides FDA-cleared AFib screening with basic ECG recording. HeartLab is an advanced ECG analysis app for Apple Watch that detects multiple arrhythmia types with detailed waveform analysis. While both record 30-second ECGs, HeartLab offers significantly deeper analysis capabilities.

Why Choose HeartLab
HeartLab goes far beyond basic AFib screening. While Samsung Health Monitor only checks for atrial fibrillation, HeartLab detects PVCs, PACs, bigeminy, trigeminy, and AFib with detailed analysis. It provides 12+ HRV metrics, Poincaré plots, cardiac scoring, AI-powered explanations, and shareable PDF reports for your doctor.
All processing happens on-device for complete privacy. Samsung Health sends ECG data to Samsung servers for analysis. If you want comprehensive heart rhythm analysis rather than just AFib screening, HeartLab is the superior choice.
Why Choose Samsung Health Monitor
Samsung Health Monitor is built into Galaxy Watch, providing a seamless experience for Samsung users. It offers FDA-cleared AFib detection, blood pressure monitoring (in select markets), and SpO2 tracking. The integrated ecosystem with Samsung phones and tablets makes it convenient for users already in the Samsung ecosystem.
For users who only need basic AFib screening and don't require detailed arrhythmia analysis, Samsung Health Monitor is a solid built-in option. However, it lacks the depth of analysis that HeartLab provides for users with known arrhythmias or more complex cardiac concerns.
FAQ
Does Samsung Health Monitor detect PVCs?
No. Samsung Health Monitor only screens for atrial fibrillation (AFib). It cannot detect PVCs, PACs, bigeminy, or trigeminy. HeartLab detects all of these arrhythmias automatically.
Can I use HeartLab with a Samsung Galaxy Watch?
No. HeartLab requires an Apple Watch Series 4 or later with ECG capability. It reads ECG recordings from Apple Health. Samsung Galaxy Watch ECG data is not compatible with HeartLab.
Which ECG is more accurate?
Both use medical-grade single-lead ECG hardware. The difference is in software analysis: Samsung only checks for AFib, while HeartLab analyzes the full ECG waveform for multiple arrhythmia types, QT intervals, and HRV.
Does Samsung Health Monitor provide PDF reports?
No. Samsung Health Monitor saves ECG recordings that you can show to your doctor, but does not generate detailed PDF medical reports like HeartLab does.
Is Samsung Health Monitor available worldwide?
Samsung Health Monitor ECG and blood pressure features are not available in all countries due to regulatory requirements. Availability varies by market. Check Samsung's website for your country.
Information accurate as of February 2026. Features and pricing may change. Check respective app stores for the latest details. HeartLab is not a medical device and does not replace professional medical advice.
