How to check task progress?
Tap a task title to enter the task's detail page.
Press on the date section of the screen to bring up a shaded progress bar which you can slide from 0% to 100% to easily record what you think the level of progress on that task is.
Note, if the task contains a checklist, progress will be automatically recorded based on the percentage of items marked completed. For example, a checklist with 2 items unchecked and 1 item checked off as completed will show 33% progress.
