Acceptance of Terms

By downloading, installing, or using CardioWatch (“the App”), you agree to be bound by these Terms of Use. If you do not agree, do not use the App.

Description of Service

CardioWatch is a health data visualization and measurement tool for iPhone that reads ECG, heart rate, and HRV data recorded by Apple Watch. The App provides signal processing, interval measurements, stress tracking, and trend analysis based on this data.

Medical Disclaimer

• All measurements, analyses, and visualizations provided by the App are for informational and reference purposes only

• The App cannot and does not perform ST-segment analysis related to myocardial ischemia or infarction
• Apple Watch provides only a single-lead (Lead I) ECG, which has inherent limitations compared to a clinical 12-lead ECG
• A 30-second recording may not capture intermittent cardiac events

If you experience chest pain, severe dizziness, difficulty breathing, or any other emergency symptoms, call emergency services immediately (911 in the US / 120 in China). Do not rely on this App.

Always consult a qualified healthcare professional for medical advice, diagnosis, or treatment.
