Here are some of the best sleep apps for Apple Watch.

1. AutoSleep

There’s no need to worry about activating AutoSleep before you turn in for the night. Living up to its name, the app automatically starts tracking sleep as long as you’re wearing an Apple Watch when you hit the hay.

Before starting for the first time, you need to go through the setup wizard. You can also tweak the app if you’re a restless sleeper. Each morning, you can see a detailed analysis of your sleep including when you were in lighter or deeper sleep, your heart rate, and how much time your sleep was disrupted for.

You can get an overall look at your sleep as a clock interface. Once you meet a custom goal, the clock switches from red to green. To see all of the data at a glance, the Today page is the place to go; it shows you information like sleep rating, time asleep, and more.
