Track car care by mileage and time. Oil, tires, inspection, battery and more—reminded gently until done. Keep your car running longer.
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.
