ECG HeartLab: EKG for Watch downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
Active users
All platforms, worldwide. Free with an account.
Stickiness (DAU / MAU)
how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum
64/100
faster than 73% of Medical apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About ECG HeartLab: EKG for Watch
Your Apple Watch records ECGs. But do you really understand what they show?
HeartLab turns your ECG recordings into detailed, easy-to-read cardiac insights that go beyond what basic health apps show you. In-depth analysis, AI-powered explanations, and PDF reports you can share with your doctor.
ADVANCED RHYTHM ANALYSIS
Standard ECG apps classify Atrial Fibrillation (AFib). HeartLab also flags possible signs of five types of heart rhythm irregularities:
• Possible Atrial Fibrillation (AFib) - Irregular heartbeat originating in the atria
• Possible Premature Atrial Contractions (PAC) - Early beats from the atria
• Possible Premature Ventricular Contractions (PVC) - Early beats from the ventricles
• Possible Bigeminy - Alternating pattern of normal and premature beats
• Possible Trigeminy - Pattern of two normal beats followed by a premature beat
Our algorithms examine every single heartbeat in your recording. Every finding is an indication to discuss with your doctor, not a diagnosis.
COMPLETE HRV ANALYSIS
Get a full picture of your Heart Rate Variability with 12+ metrics:
• SDNN - Standard deviation of NN intervals, a widely used HRV indicator
• rMSSD - Reflects parasympathetic nervous system activity
• pNN50 - Percentage of adjacent intervals differing by more than 50 ms
• Poincaré Plot - Visual representation of heart rate dynamics
• Cardiac Score - Our proprietary score combining multiple metrics
The same metrics used in cardiac research, now on your iPhone.
AI-POWERED EXPLANATIONS
Medical terminology can be confusing. Our AI assistant explains your ECG results in plain language, answers your questions, and helps you understand what your heart data means. Results are shared with the AI service only when you ask.
DETAILED PDF REPORTS
Generate detailed reports to share with your doctor. Each report includes:
• Complete ECG waveform visualization
• All measurements and intervals
• HRV metrics and trends
• Possible anomalies and patterns found
• Historical comparison
SEAMLESS INTEGRATION
• Automatic ECG import from Apple Health
• No manual export or complicated setup
• Record your ECG, see the analysis in seconds
• Complete history access
• Organized timeline view
PRIVACY BY DESIGN
Your ECG recordings are analyzed on your iPhone with algorithms optimized for mobile devices. Your health data is never sold and never used for advertising.
DESIGNED FOR EVERYONE
Whether you're keeping an eye on a known condition, tracking athletic recovery through HRV, or simply curious about your heart, HeartLab gives you insights in a format you can understand.
Trusted by thousands of users in 47+ countries. Join them today.
