¹ScanWatch 2 incorporates the medical device software Withings ECG App. Withings ECG App enables the detection of atrial fibrillation through ECG readings. The ECG functionality has been cleared by the FDA. Please read the user instructions carefully. If you have any concerns about your results, consult your doctor. (08/08/2025)

²Temperature tracking is designed to indicate deviations from your typical temperature pattern and is not a medical thermometer. Temperature data should not be used to detect fever, or to diagnose, treat, cure, or prevent any disease. For accurate measurements or in case of symptoms, use a clinical thermometer and always consult a healthcare professional.

³The predicted fertility window and retrospective ovulation confirmation provided are for informational purposes only and are not medical features. It should not be used for the control or support of conception. Always consult a healthcare professional for fertility or reproductive health guidance.

⁴The ECG and irregular heart rhythm notification features have not been tested and are not intended for use in people with cardiac pacemaker, implantable cardiac-defibrillator, or other implanted electronic device.
