The Apple Watch is one of the most popular health-tracking devices and includes a built-in sleep tracker or can be compatible with many iPhone sleep tracking apps. The selection of apps gives wearers of this band the freedom to experiment with different sleep trackers. To do so, simply download the Apple Watch App of your choosing, like SleepWatch or Bodymatter, to track your sleep.
Reason to Buy: The beauty of the Apple Watch is that you can choose the sleep app you like based on the data it provides, how it works, and its interface. While the watch is an investment, it’s practically a computer that wraps around your wrist, so you’ll enjoy its many other features with your purchase like activity tracking and music. Keep in mind that you’ll need to be wearing this device as you sleep to gather data for most compatible sleep apps, so if having a watch on in bed bothers you, it might not be your best choice.
