Todoist creates automatic reminders for tasks that have a due date or associated time. For example: if your task is due today @ 10am, Todoist will automatically send a reminder 30 minutes before this deadline.
Setting reminders manually
It's easy to manually set and manage reminders. To do this, simply:
Open a task's menu by clicking on the gear icon ().
Click Reminders menu item to open up a window where you can manage your task's reminders.
Set quick reminders when adding or updating tasks
When adding or updating a task, you can set a reminder directly in the task's text. For example, if you'd like to be reminded about a task at 2pm, type <remind today at 2pm> after the task description in the text box, and then save the task.
This even works when you add tasks from our widgets, via email or mobile.
