Key features of watchOS 9

Exercise : In watchOS 9, you can adjust the interval between exercise and rest in the Workout app. In addition, there are Heart Rate Zones, which analyze exercise intensity using previous exercise history and health data. For users who run frequently, it helps to exceed the usual record by changing the target distance according to the situation. By measuring data such as stride length, ground contact time and vertical oscillation, you can analyze your running performance more deeply. Here, they supported data verification using the Digital Crown. As for the type of exercise, a triathlon has been added this time, allowing you to easily switch between swimming, running and cycling without complicated procedures. It also automatically recognizes the process of swimming using the keyboard.

sleep tracking : The sleep tracking function in watchOS8 was at the level of calculating the amount of time in bed without deep analysis of sleep stages. However, starting with watchOS 9, more accurate sleep tracking is supported. It separates and analyzes REM sleep, core sleep, and deep sleep, and displays the level of sleep in a graph. When used with Apple’s Health app, it’s a good way to track your sleep health.

Medication Reminder : The Health app tracks new medications and tells you when to take them. You can also easily record whether or not you have taken your dose through the Apple Watch.

watch face : The Metropolitan, Playtime, and Celestial watch faces have been added to watchOS 9. There is also support for the Chinese, Hebrew, and Islamic lunar calendars, as well as a lunar pace that uses lunar phases to indicate time. The ability to display custom information on the existing watch face has also been updated, and pet photos can be easily moved to the watch face. Edit mode allows you to change the color tone of the portrait background. The background color has also become more diverse.

notification banner : Notifications are displayed in the form of a banner so that the watch is not disturbed while the watch is in use, and when the wrist is lowered, the banner is displayed again in a full screen format.

family setting : This is a new feature made for users with children, allowing you to control your HomePod speaker or smartphone device without having to connect an iPhone. If you use the wallet app, you can use it as a home or hotel key.
