The Ankang Guardian APP is an application focused on health management. Its main functions include real-time monitoring and recording of key health indicators such as heart rate, electrocardiogram, body temperature and blood oxygen saturation. Users can automatically synchronize these data to the APP by pairing a smart bracelet, forming an easy-to-understand table or curve chart for long-term tracking of health status. In addition, the APP also supports message reminders to ensure that users will not miss any important notifications.
