Marking a post as complete is a way for you to tag an analog activity either posted by you or by others as complete as the app itself works as a checklist for you to cross out some of the tasks you were working on.
To mark an analog as complete:
- Hit the hamburger menu button right next to the feed.
- Select Mark as Complete.
Please note that marking any analog post or activity as complete cannot be seen by other users. It is only visible only to you.
