## What is CarKeep?

When was your last oil change? Time for a tire rotation? How many days until inspection?
CarKeep is a maintenance log for drivers that tracks your car's care by two axes: mileage and time.

■ Mileage × Time
Oil changes and tire rotations are tracked by mileage; inspection and battery by time. Each item uses the right axis, so you see "Oil change in ~300 mi" at a glance.

■ Core items, ready to go
Just add your car and the key items—oil change, tire rotation, inspection—are set up automatically. Add oil filter, brakes, coolant, wipers, air filter, wash & wax and more.

■ Gentle, persistent reminders
Get notified before each item is due. Even if it slips by, CarKeep reminds you kindly every day until it's done—so nothing falls through the cracks.

■ Manage your car with photos
Add a photo of your car (the subject is cut out automatically). Manage multiple vehicles and switch between them from the top switcher.

■ Service log & mileage log
Record when, at what mileage, and how much each service cost—handy for resale value and predicting the next due date.

■ Daily care tips
Get a practical maintenance tip every day to keep your car running longer and better.

■ Widget
See the next car that needs care and how much is left (mi / days) right on your home screen.
