Apple Watch already tracks several aspects of your health, from heart rate, exercise minutes, steps, and more. But soon it will be capable of tracking your sleep. With an official Sleep Tracking feature by Apple.
Sleep Tracking will come to Apple Watch via watchOS 7, a free software update coming this Spring. The feature will be capable of providing an insight into how well you sleep and help you sleep better. By reminding you when you should head to bed, capturing how well you sleep, and more.
As you wake up in the morning it will be possible to view a chart of how well you slept. Including how long you slept for and periods of wakeups. Other information will also be collected including heart rate and noise levels.
Other features of Sleep Tracking include:
wind Down allows Apple Watch and iPhone users to create a customised routine before bed.
setting up a specific scene in the Home app, listening to a soothing soundscape, or using a favourite meditation app
sleep Mode, Apple Watch turns on Do Not Disturb and automatically darkens the screen overnight
silent haptic alarm or gentle sounds to help wake up
remind users to charge it ahead of sleep
Sleep Tracking is possible due by detecting micro-movements by the accelerometer in Apple Watch.
All Apple Watch models which support watchOS 7 will gain the Sleep Tracking feature. Eligible models include Apple Watch Series 3, Apple Watch Series 4, or Apple Watch Series 5 paired with iPhone 6s or later running iOS 14 or later.
