From a bedtime to a weekly routine
A plan for every day
Save a calculation as a weekly plan. Set different wake-up times for weekdays and weekends, and see a suggested bedtime for each day.
Bedtime reminders
Preview when a reminder will arrive, then set it for 15, 30 or 60 minutes before a planned bedtime. You can also set a custom time.
A simple sleep journal
Enter when you got into bed, when you think you fell asleep and when you woke up. Review your seven-day trend and average for the days you logged.
On your iPhone
Calculations, plans and the journal work offline. Your plans, entries and preferences are stored on your device. No account is needed.
Choose English or Simplified Chinese, a starry or rainy sky, and Night, Daylight or System appearance.
Help and privacy
Journal entries are your estimates. Bedtime reminders are optional iOS notifications. For setup and troubleshooting, visit support.
