Frontier Medical Innovation launched the smart wearable health APP - Frontier Health, which is suitable for JY Watch. JY Watch is a wrist-worn device, which is used to non-invasively measure, display and store general physiological parameters, such as heart rate/breathing/blood oxygen, etc. The APP can quickly view and share monitoring information, and can also cover many functions such as health management, exercise measurement, sleep monitoring, and stress index measurement. The data collected and measured by the App by JY Watch is not for medical use and is for reference only.
