Completing tasks is easily the most satisfying part of using Todoist. And if you complete a task you didn't mean to, or need to bring a completed task back, you've got the ability to uncomplete tasks, too.

Completing a task

Completing a task on your to-do list in Todoist can be done in one simple step:

Click on the circle to the left of the task you want to complete.
Click on the circle to the left of the task you want to complete.
Tap the circle to the left of the task you want to complete. 
Tap the circle to the left of the task you want to complete. 
You can complete multiple tasks at once, too.

Uncomplete a task

In some cases, you may accidentally complete a task. Or you might complete a task then realize there’s still work to do. In those cases, you can uncomplete the task:

  1. While viewing your project, click on the three dot icon at the top right of your task list and select Show completed tasks from the menu.
  2. Find the task you’d like to uncomplete and click the circle with the check mark to the left of the task.
  1. While viewing your project, click the three dots icon at the top right of your task list and select Show completed Tasks.
  2. Find the task you’d like to uncomplete and click the circle with the check mark to the left of the task.
  1. While viewing your project, tap the three dots icon on the top right corner and select Show completed Tasks.
  2. Find the task you’d like to uncomplete and tap the circle with the check mark to the left of the task.
  1. While viewing your project, tap the three dots icon on the top right corner and select Show Completed Tasks.
  2. Find the task you’d like to uncomplete and tap the circle with the check mark to the left of the task.
After sub-tasks are completed, they will disappear. If you want to uncomplete these tasks, click/press the "Show completed tasks" option in the top right menu, and then you'll find the completed tasks below where they were completed - you can then uncomplete them there. 

FAQ

Q: Can I uncomplete recurring tasks?

A: The completion of recurring tasks can only be undone right after the occurrence has been completed, by clicking “undo” in the popup (web, Windows, macOS) or by tapping the undo popup (iOS, Android) which appears at the bottom of your screen.

It’s not possible to undo any previous occurrence of the task. For example, if you have a task due everyday, and you complete it today, you can only undo today's task. You can't undo any previous occurrence of the task.

Note that you won't be able to undo the recurring task once the pop up message disappears. Instead, you can create a new task or just reschedule your existing task by adding a new recurring due date that starts at your previous instance.

Q: How can I permanently complete a recurring task?

A: When you're done using your recurring task, you can simply complete it forever:

Right-click on a task and select Complete forever.
  1. Tap on a task to open task view.
  2. Tap the android_three-dots-icon.svg three dots icon.
  3. Select Complete forever.
  1. Tap on a task to open task view.
  2. Tap the ios_three-dots.svg three dots icon.

Q: Can I swipe to complete tasks on Todoist for iOS and Android?

A: Absolutely! While the default behavior for swiping right is now to select tasks, you can customize this. To change what happens when you swipe over a task, go to Settings → General and choose the desired action.

Q: When I uncomplete a sub-task, will it also uncomplete its parent task or section?

A: Yes, whenever a sub-task is uncompleted, all its parents are uncompleted with it.
