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. [Free] 1 car, up to 3 care items [Premium] Unlimited cars & items / full history / storage groups / no ads - Lifetime ¥3,000 (one-time purchase, yours forever) - Weekly ¥200 * Subscriptions auto-renew unless canceled at least 24 hours before the period ends.
