**Vehicle Registration and Management**

You can register and manage multiple vehicles with a single account. Enter a nickname, license plate number, manufacturer, model name, fuel type, and initial/current mileage for each vehicle. The entered information is automatically linked to the corresponding vehicle when recording refueling or maintenance. If you designate a frequently used vehicle as your primary vehicle, you can immediately check its information and recent expense history on the home screen.

**Refueling Log**

When refueling, you can enter and save the date, amount, mileage, fuel quantity (liters), price per liter, gas station (location), and memo. Pressing the 'Refueling Log' button on the home screen takes you directly to the input screen, where the mileage of the currently selected vehicle is automatically entered, allowing for convenient recording.

**Maintenance Log**

You can enter and save maintenance details (e.g., engine oil, tires, parts replacement, etc.) along with the date, amount, mileage, maintenance item, repair shop (location), and memo. You can quickly enter information using the 'Maintenance Log' button.

** **Other Expenses**

Expenses other than fuel and maintenance (car wash, parking, tolls, etc.) can also be recorded by date, amount, mileage, memo, and location.

**Checking and Modifying Expense History**

On the 'Expense History' screen, you can view all saved records categorized into All, Fuel, and Maintenance tabs. Tapping each item allows you to edit or delete it, and you can also filter the data by selected vehicle.

**Statistics**

On the 'Statistics' screen, you can view the following information:

- **Monthly Statistics**: Displays the total monthly expenditure and the ratio of fuel, maintenance, and other expenses in chart and list formats. You can also view data for the previous month by month.

- **Annual Statistics**: Displays the total annual expenditure and the ratio of each item in chart and list formats.

- **Fuel Economy**: Calculates and displays the fuel economy (km/L) for the selected period (last 3 months, last year, all, or custom setting). Fuel economy is automatically calculated based on fuel records.
