FitRing is a lifestyle application designed to work seamlessly with the HJ08 smartwatch by Shenzhen Intelligent Age Technology Co. Ltd. By connecting to the HJ08 watch, FitRing offers several key functionalities. Firstly, it allows users to receive notifications and SMS on the watch, enabling quick replies. Secondly, users can make and receive calls directly from the watch without the need to access their phones. Additionally, FitRing compiles health data such as heart rate, blood pressure, oxygen levels, sleep patterns, and exercise statistics measured by the HJ08 watch into a convenient statistical format for users to monitor. Lastly, the app utilizes the location feature during running mode in the Atrol application to track the user's movement path, providing a comprehensive view of health data during exercise.
