Priority Matrix for Android allows you to filter and sort items in a few ways. To access Priority Matrix’s filters, select the funnel in the bottom right-hand corner of the app.

You will see the options for “Filter Mode” and “Sorting Mode”.

Filter Mode allows you to sort items based on completion status. When you check items as completed, they don’t disappear, they are simply removed from your view; in order to access them again, you can select “all items” or “finished items”.

The Sorting mode allows you to re-arrange tasks within quadrants. If you select “earlier items first”, for example, items with the earliest due dates will be brought to the top of each quadrant.
