KIE OS is a supporting application designed for smart watches. Developed by 展传 彭, this app offers a range of features to enhance the user experience. With the user's consent, KIE OS utilizes permissions such as SMS and phone calls to send monitored information to the smart watch via Bluetooth.

One of the main functions of KIE OS is to record heart rate data collected by the smart watch. This data is displayed in the form of a line graph and a histogram, allowing users to track their heart rate trends over time. Additionally, the app records sports data including the number of steps, stride frequency, and distance. These metrics are also presented in the form of line graphs and histograms, providing users with a visual representation of their physical activity.

In addition to health tracking, KIE OS allows users to set reminders and alarms directly from their smart watch. This feature helps users stay organized and on top of their daily tasks.

The app also offers several other features to enhance the overall user experience. Detailed data provided by KIE OS helps users exercise more rationally and scientifically, while exercise and sleep goals encourage a healthy lifestyle. Users can also share their exercise information with others, promoting a sense of community and motivation. Furthermore, KIE OS offers a wide variety of dials, including custom options, allowing users to personalize their smart watch interface.

It is important to note that KIE OS only supports iOS 9.0 or later and must be used in conjunction with the Watch Zs smart watch to fully utilize all its features.
