These two strategies can only be used along the time tracking strategy. 

Time targets are all about setting daily goals for yourself to meet. 

So let's say every day you want to spend at least 90min on marketing your business or every Monday, Wednesday and Friday you want to spend at least 60 min doing something for your health. 

You can then set up those targets based in the strategy settings like this:

Targets can be set for any category or project and even per label ("add label target"). You can also set them up using Smart Lists by clicking on the "Add Smart List Target" button.

You can also set up different targets for the same category or label by just using multiple rows:

Targets can be deleted or changed anytime. To delete a target hover over the row and click the trash icon that appears on the right.

Your targets show up as progress bars each day like this:

As you track time on tasks the progress bar goes up.

If you do not see your targets in the day view they are likely hidden. You can show/hide them with the target icon on the very right of the screen. The menu shows when you start moving your mouse on the very right of the screen.
