How do I use the Night Schedule presets?

Start by going to the Scheduling section of the parent app. You can select Weekday Night, Weekend Night, or both.

Toggling the slider will disable access to the phone's features during the time interval. By default, the night interval runs from 9:00pm to 8:00am. You can change the time interval by dragging the Bell to the start time and the Moon to the end time.
