After you've created your first thing, you should see it show up in your dashboard. The dashbaord is a collection of things (like 'My Car' in this example) and tasks associated to that thing (like 'Change Oil' in this example).
Each task is color coded to indicate how much more time you have until it is due. Red is overdue, yellow is almost due, blue is a little ways out, and green is a long ways out.

If you want to set exactly when this was last done, hit the 'calender' button.
