Vroom Car Log: Fuel & Mileage

Spend 30 seconds at every fill-up and get a clear picture of what your car actually costs you — Vroom Car Log is a simple, manual-entry car maintenance logbook.

Most big car management apps require an OBD dongle, an account, and push you into a community/insurance ecosystem. Vroom Car Log is the opposite: no account, no server — every record stays on your phone, fully offline.

■ Automatic fuel economy (full-tank method)
Just enter the date, odometer reading, fuel amount, and cost each time you fill up. The app automatically calculates your real fuel economy (km/L) between full tanks, and rolls partial fill-ups into the next full tank.

■ Consumable replacement reminders
Set a replacement interval (distance and/or months) for engine oil, cabin air filter, tires, wiper blades, brake pads, coolant, and battery — or add your own custom item. A remaining-distance gauge and D-day badge tell you when it's time, with a local notification when it's coming up.

■ Track maintenance and other expenses
Log maintenance, car washes, insurance, tolls, and parking, and see this month's total spend right on your home dashboard.

■ Stats at a glance
Charts for monthly spending trends, fuel economy trends, and this month's spending breakdown by type.

■ Multiple vehicles
Switch between vehicles from the top of the home screen and manage each car's records separately.

■ Privacy first
No sign-up, no login. Every record you enter stays on your device and is never sent to a server.

■ Language
Available in Korean and English, switchable in Settings.

Perfect if you commute in your own car and want to know your real fuel economy, keep forgetting when you last changed your oil, or just want to know how much your car costs you each month.
