Alarm reliability
Allow notifications, raise system volume, and review Focus and Silent Mode before relying on an ordinary notification alarm. Use Test Alarm in Settings before your first nap.
PowerNapTime
Find answers for alarms, Apple Watch, Apple Health, privacy, and Smart Wake. PowerNapTime is a wellness utility and does not provide medical advice or clinical sleep-stage detection.
Allow notifications, raise system volume, and review Focus and Silent Mode before relying on an ordinary notification alarm. Use Test Alarm in Settings before your first nap.
Automatic mode prefers a reachable Apple Watch. Without one, PowerNapTime can use private on-device iPhone audio sensing. The displayed hard deadline remains the fallback.
Health access is optional. Historical stages are shown only when Apple Health provides them. You can change access in the system Health and Privacy settings.
Open Settings, then Your data, to delete all nap history stored by PowerNapTime. Apple Health samples are managed separately in the Health app.
