Q: Does sleep auto track?

Hi

Apple Watch does not include sleep tracking as a built-in feature.

Some third-party apps offer sleep tracking features. Some of these also require a related third-party accessory, whereas some others use the watch's own sensors.

You may, for example, find the following sleep tracking apps of interest (the first two of which do not require a third-party accessory):

• Sleep++ (uses Apple Watch)

Hi

The first two apps (which do not require a third-party accessory) still require you to start and end the sleep monitoring process.

Each is able to share your sleep data to the Health app on your iPhone.

If you would like to suggest that Apple considers adding sleep monitoring as a built-in feature, including with the automated functionality that you describe, you can do so here:
