Due date is whatever date your burp need to be checked off your list. The Due date decides which of the filter-views your burp will show in.
When the Due date is reached, you’ll get an in-app notification and a web push notification (if you have enabled push).
If you have an extra important burp, or something that may need some time to check off your list, it may be a good idea to send yourself a Reminder a bit ahead of the Due date!
Depending on your notification settings, you’ll be notified by push and/or email on the day of the Reminder.
Setting Reminders won’t affect which filters the burp shows in.
You can see in the list view if a Reminder has been set, just look for the alarm-clock symbol.
