Earlier in June, Apple declared that its watchOS 7 features enhanced customization tools and powerful new health and fitness functions, among which, there's the sleep tracking function. With watchOS 7, Apple Watch lets you know how well you are sleeping. It simply helps you get the desired amount of sleep, set an ideal schedule for bedtime routines. However, the world's most advanced smartwatch, the Apple Watch doesn't emphasize the sleep tracking function too much, because the watch doesn't come with its own sleep app. It could be the high demand of battery consumption, so Apple wants to skip this app running in the watch.

But, fortunately, there are many third-party sleep apps for Apple Watch. These apps work greatly as a sleep tracker. Let's see 8 best sleep apps for Apple Watch. They might work in the way you like.
