How to use
Combine time to fall asleep and time asleep to calculate your timer in minutes.
The plan uses about 20 minutes for a short nap and about 90 for a longer rest.
The default 15 minutes to fall asleep is an adjustable planning assumption.
Sleep cycles and how you feel on waking vary.
Frequently asked questions
Can I sleep longer than suggested?
Sleeping for 30–60 minutes can mean waking during deep sleep. An explanation appears when the plan shortens your available time.
Is time to fall asleep included?
Yes. With the default 15-minute allowance, a 20-minute nap becomes a 35-minute timer, and 90 minutes asleep becomes 105 minutes.
Is the wake-up time exact?
It adds the timer duration to your chosen starting time. It does not measure your sleep.
