Bedtime notification
Sends you a "Time to go to bed!" notification before bedtime.
Bedtime notification is an effective way to maintain optimal sleep duration or to combat sleep deficit. You can set the alert to go off anywhere from 5 minutes to 2 hours before bedtime, so you’ll have plenty of time to get ready for bed.
