Track Your Sleep
Sleep tracking is a fairly new feature that came to the Apple Watch a few years ago. As you can guess by its name, you can use it to track how well you sleep every night and get insights for your day, week, or month.
What’s great about the Apple Watch’s built-in sleep tracking feature is how well it works with other Apple Watch features.
For instance, you can also keep track of your heart rate throughout the night and even keep track of your respiratory rate and the oxygen levels in your blood, but we’ll talk more about that in a minute.
Sure, there are many other apps that can also track this, but with the integration of sleep schedules and sleep goals, as well as automatically being able to trigger your Focus modes, your Apple Watch’s sleep tracking is one of the best ones you can use.
Plus, you can use all of these features at no extra cost.
