Reminders are placed into four categories which can be found at the top of the screen; "Today", "Scheduled", "All", and "Flagged". Users can also create their own lists of reminders. New reminders can be placed into lists or set as subtasks and can include several details including: a priority tag, a note about the reminder, and an image or
URL attachment. Tasks appear in the
Notification Center 24 hours before the time a reminder is set for. Additionally, alarms can be set for reminders, sending a notification to users at a certain time and date, when a
geofence around an area is crossed, or when a
message starts being typed to a set contact. If a time-based alert is set, it can repeat every day, week, two weeks, month, or year. Reminders can be marked as completed (checked) and are automatically hidden. Lists can be synced between iOS, macOS, watchOS, iPadOS and visionOS through
iCloud as well as shared with other contacts. Once shared, tasks can be added or completed by anyone with access to a list and specific reminders can be assigned to different people. ==References==
