Hello,

You can review them in Archiver which is only supported on the web version.

Go to Completed box first and there are two icons below the Settings button at the top right corner. Click on the right icon and it will go to the Archiver.

And now, tasks completed 30 days ago will be archived automatically. Besides, when there are more than one hundred tasks in Completed, they will be archived automatically as well. And now you can view your archived tasks only in the web version.

Shall you need any help or have additional questions, please feel free to contact us.

Thank you for your feedback and support.

cool~ @michelle1987, thanks for your rapid response.
I can review my task completed 3 months ago in archiver now.

One more question:
According to your introduction, tasks completed 30 days ago will be archived automatically.
But the earliest date I can find in my Completed list is 15 Jan(2013) which is 97 days ago.
On the other side, the total number of the task in the Completed list is just 100.
Can you show me how dose the archiver work?

Thanks again and good night.

We feel so sorry, our rule now is changed. When there are more than one hundred tasks in Completed, they will be archived automatically.

For example, now if there are 100 tasks in Completed and the earliest one was completed on 15 Jan(2013), it will first go to Archiver when now you complete another more task.

Also, you can manually archive tasks. In Completed box, click on the Archive icon on the top (see in attach file).

Please don't hesitate to contact us if you have further questions.

Afternoon, @michelle1987
I understand the rule of archiver and feel more convenient in use now.

Thanks for your particular explanation, have a nice day:)
