Reminders are like instant messages but are scheduled to start at a future time. Reminders can also be set to be "recurring" either daily, certain days of a week, every other week, monthly, or annually (e.g. birthdays).
Reminders have additional options related to the "agenda view" feature:
Show as Cue on Day Clock - if unchecked this reminder will not show on the day clock. Instead, it can be used as in internal reminder for family members.
Show on Day Clock Agenda - if unchecked this reminder won't appear in the Agenda View but will still show at its schedule time.
Show End time on Agenda - if unchecked only the start time for this reminder will show on the Agenda view.
Color Category - select the background color to use on Agenda view.
By default reminders show for 15 minutes from the time they become "active".
To schedule a reminder:
From the home screen click on the + action button in the lower right of the screen.
Select "Schedule Reminder".
Enter the message for the reminder and select any additional settings.
Click the "✓" in the upper right hand corner.
