Car Expenses: full visibility on your real car cost

Car Expenses is the OneKitPlus app built to track fuel, maintenance, insurance, tolls, parking, and all other car-related transactions in one place.

Why it matters

  • Know your true monthly vehicle cost.
  • Avoid spreadsheets and duplicate input.
  • Get instant reports by category and period.

Main features

  • Fuel entries with odometer, quantity, and full tank option.
  • Custom categories and category manager.
  • Reminders for deadlines and services.
  • Multiple vehicles per account.
  • CSV, Excel, and printable PDF export.

Smart fuel logic

With full-tank logic, consumption is calculated between complete refuels. Partial refuels remain pending until the next full tank for better accuracy.

Budget integration

If you also use Budget, Car Expenses no longer enables sync silently and automatically for new users. On first use, the app shows a clear in-app choice.

  • Enable sync: new car transactions can also be added to Budget, so you avoid duplicate entry.
  • Keep separate: use Car Expenses as a standalone app without sending new transactions to Budget automatically.
  • The choice is shown in the active interface language and can be changed later inside the app.

Accounts that already had linked car data remain compatible and keep their existing alignment.

Privacy

Data is isolated per user account, and each user can export their own records anytime.
