CardioWatch Pro
Stress Insights & Heart Rhythm
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
CardioWatch tracks your daily stress and turns Apple Watch ECG recordings into a detailed heart health timeline.
Your Apple Watch quietly monitors your body throughout the day. CardioWatch transforms that data into an intuitive stress timeline based on your personal baseline. When you record an ECG, it goes beyond Apple's basic report — displaying QTc, PR, and QRS intervals, and labeling signal features such as PVCs.
WHAT MAKES CARDIOWATCH DIFFERENT
- Stress Timeline
See your entire day mapped as a stress timeline with an intuitive 5-level scale based on your personal baseline — not generic population averages. Powered by Heart Rate Variability (HRV) analysis.
- Deep ECG Analysis
Every 30-second ECG recording is processed locally on your iPhone. You get interval data with clinical reference ranges — not just "normal" or "abnormal."
- ECG + Stress, Connected
The only app that places your ECG recordings on your stress timeline. See exactly when ECG recordings align with your daily stress patterns.
- PDF Reports for Your Doctor
One-tap export of a comprehensive report including ECG waveform, measurements, stress context, sleep data, and symptom tags. Give your doctor the full picture.
- Lifestyle Insights
Discover how sleep, exercise, and activity patterns affect your stress and recovery. Personalized analysis based on your own data.
