HeartLab transforms your Apple Watch ECG into comprehensive cardiac insights that even your doctor will appreciate. Advanced arrhythmia detection, complete HRV analysis, AI-powered explanations, and professional medical reports.
HeartLab goes far beyond what Apple's Health app shows you. Here's what makes us unique.
While Apple Watch only detects AFib, HeartLab identifies PAC, PVC, Bigeminy, Trigeminy, and suspected Atrial Fibrillation. Our algorithms analyze every single heartbeat to find patterns that other apps miss completely.
Don't understand medical terminology? Our AI assistant explains your ECG results in plain language, answers your questions, and helps you understand what your heart data actually means.
Get the full picture of your heart rate variability with SDNN, rMSSD, pNN50, and Poincaré plots. The same metrics used in professional cardiac research, now accessible on your iPhone.
Generate detailed medical-grade reports that you can share with your cardiologist. Include ECG waveforms, measurements, HRV data, and detected anomalies in a format doctors recognize and trust.
HeartLab analyzes your ECG with the same rigor as professional cardiac equipment
Professional tools designed for everyone, with the simplicity you expect from the best apps.
HeartLab seamlessly connects to Apple Health and automatically imports all your Apple Watch ECG recordings. No manual export, no complicated setup. Just record an ECG on your watch, and it appears in HeartLab within seconds.
Our advanced algorithm identifies each R-peak in your ECG waveform with high precision. This is the foundation for all our analysis - accurate peak detection means accurate heart rate, HRV, and arrhythmia detection.
Track how your heart health evolves over time. HeartLab stores all your ECG analyses and shows you trends in your heart rate, HRV metrics, and arrhythmia occurrences. Spot patterns that could indicate improving or declining cardiac health.
The technology behind HeartLab ensures accuracy, reliability, and complete data privacy.
Your ECG data never leaves your iPhone. All analysis is performed locally using advanced algorithms optimized for mobile devices. No cloud processing, no data uploads, complete privacy.
Designed with healthcare data regulations in mind. Your sensitive health information is protected with the highest standards of data security and privacy protection.
Seamless integration with Apple's HealthKit framework. HeartLab reads your ECG data directly from Apple Health, ensuring compatibility and data integrity.
Our team of developers and cardiac health experts continuously improve HeartLab's algorithms and add new features based on the latest research and user feedback.
Getting clinical-grade ECG analysis has never been easier.
Get HeartLab free from the App Store. The app requires iOS 15 or later and an Apple Watch with ECG capability (Series 4 or newer).
Allow HeartLab to read your ECG data from Apple Health. This is a one-time setup that enables automatic sync of all your recordings.
Use your Apple Watch to take an ECG as you normally would. The recording automatically appears in HeartLab for analysis.
