"Due" lives on my task bar.

Reminders" is free so why pay for "Due?" Because "Due" will gently nag you until you either accomplish the task or consciously postpone for a set amount of time. At which point the nagging starts again. If that sounds annoying consider how annoying it is to look at a regular reminder, think "oh yeah Ill do that shortly" and then you forget anyway. "Dues" interface is super simple which makes "Due" an app I use multiple times per day.
