But how can I track my sleep as I actually don`t know when I`m sleeping and how long? Thought this would be a feature of the Apple Watch.
Certain apps, such as Sleep Cycle, track your sleep. You open the app, indicate that you are going to sleep and place the phone on the edge of your bed, near your pillow. It then records your movement throughout the night, and does analysis on the quality of sleep you had based on periods of time with no movement, little movement, or lots of movement. When you wake up, you pick up your phone and indicate that you are now up.
This data would then be fed to the health app to compile an overall picture of your quality of sleep. The app itself does this, but, the benefit of having it feed into the Health app is you could see your sleep data along with your other health data at once.
It's likely that when the Apple Watch is released, it too can track your sleep due to its Accelerometer and may negate the need for other such sleep apps.
