Everything your fuel log needs. Nothing it doesn’t.
CarLog focuses on the numbers drivers actually use: consumption, costs and a clean refueling history.
Refueling history
Every refueling is kept in a clean history, grouped by month, with the amount, cost, odometer and consumption.
Fuel statistics & charts
See this week, month or year at a glance: distance, fuel used, average consumption, total spent and cost per kilometre.
Gasoline & LPG support
Filled up both petrol and LPG at the same stop? Record them as one refueling, each with its own liters, price and “Full tank” switch.
Vehicle information
Set up your car once: brand, model, optional year, fuel or energy type, current odometer, distance unit and currency.
Home-screen widgets
Small and medium widgets show your consumption, odometer and this month’s fuel cost without opening the app.

FAQ
Questions, answered
What is CarLog?
CarLog is a car and fuel tracker for Android. You log each refueling — liters, price and odometer — and CarLog shows your real fuel consumption, your fuel costs and how they change over time.
How do I track fuel consumption?
Each time you refuel, tap “Add refueling” and enter the liters, the price per liter and the odometer reading. CarLog calculates the total for you and fills in the date, the odometer and your last price to save time.
After two refuelings of the same fuel, CarLog shows your average consumption. For the most accurate figure, fill the tank completely and keep the “Full tank” switch on.
Can I track gasoline and LPG?
Yes. Petrol (gasoline) and LPG cars can record both fuels. If you buy both at the same stop, add them to the same refueling — each fuel keeps its own liters, price and “Full tank” switch, and consumption is calculated separately for each fuel.
Can I review previous refueling records?
Yes. History lists every refueling grouped by month, with the amount, cost, odometer and consumption. Tap a record to edit it; deleting a record asks for confirmation first.
Does CarLog support home-screen widgets?
Yes. CarLog offers a small and a medium home-screen widget showing your consumption, odometer and this month’s fuel cost. The medium widget includes a Refuel button that opens “Add refueling”.
To add one, touch and hold an empty area of your home screen, tap Widgets, find CarLog and drag a widget into place. On supported launchers the app can also offer to place it for you.
Where can I download CarLog?
CarLog is being prepared for release on Google Play and is not publicly listed yet.
Once the official listing is live, every download button on this website will link to it.
How can I contact the developer?
Contact details are listed on the Contact page.
What information does CarLog collect?
The current version of the app does not send your car or refueling data to the developer or to any server. Your records are stored in a database on your device, and the app contains no analytics, advertising or tracking tools.
