Thank you very much for using our product, the App is a companion app for our watch. The App can synchronize data such as steps, calories, mileage, sleep and exercise records recorded by your watch. The newly designed UI can display your data in a more user-friendly and beautiful way. After you bind and authorize, we will push the phone call and text message content to the watch to prevent you from missing key information. You can use the App to configure the watch's sedentary reminder interval,
