We receive your health data from the Health app that is synced to your Apple Watch. While the Health app tracks your heart rate and steps, it’s yet to join the party with your sleep data. But not to worry, there are plenty of clever sleep apps out there ready to bridge this gap.
If your Health app is lit up in purple, these data entries are what we call 'in bed' values. They are manual, pre-set entries created by the Bedtime app when you set an alarm.
Whilst 'in bed' data is useful, it's not a true indication of the time you've spent 'asleep'. A third party app is still required to record your actual sleep.
When choosing a sleep app make sure it is compatible with Health - Apple Watch wearers recommend free apps such as Pillow Automatic Sleep Tracker or Sleep Cycle Alarm Clock.
When you install your sleep app it will request permission to allow your data to be shared with Apple Health – be sure to ALLOW this access (doing so ensures that we will receive your sleep data via HealthKit).
