The care plan, as it exists, isn't very useful. Manually entering a due date or mileage for each item is too tedious. If the long term goal is to make Bouncie a one-stop app for everything about your car, it needs to a) track gas mileage and b) have the maintenance items recurring. Have a drop down so you don't need to type in "Oil Change" or "Registration" and then another for "every 5000 miles, or 6 months" etc. 

 As an example of a fantastic app for this, look at "Carfax Car Care" it even lists the car manufacturer's maintenance schedule.
