Apple Health Behavior

Background Reading Sync

There are situations where Apple Health background sync is stopped and requires the app to be relaunched. These situations include:

• When the user explicitly kills the host app by swiping up on it from the App Switcher.
• When the OS kills the app due to low memory, low battery, etc.
• When the device is rebooted.

The user must restart the host app to resume background sync of Apple Health data.
