CarCostKeeperBook

CarCostKeeperbook is a focused, fully offline iOS companion built for drivers who want a clear picture of what their car actually costs to own. With a few taps you can log every category of vehicle spending — fuel and charging, scheduled maintenance, unexpected repairs, insurance, parking, tolls, fines, annual inspection, car wash, and anything else. The app organizes those records by vehicle and date, surfaces a monthly summary on the main screen, and gives you deeper analytics such as fuel economy, average price per liter, cumulative mileage, and a real cost-per-kilometer figure that updates as you drive. You can also set local reminders for important dates like insurance renewals and inspections, manage multiple vehicles in one place, switch the currency symbol, and export every record to a CSV file at any time.

What sets CarCostKeeperbook apart is its disciplined approach to privacy and simplicity. There is no account creation, no cloud sync, no analytics SDK, and no advertising. Every byte of data stays on your device inside the standard system store, which makes the app fast, predictable, and easy to trust. The interface follows a clean card-based design that scales from quick one-tap logging to detailed monthly review, so casual users and meticulous owners feel equally at home.

CarCostKeeperbook solves a problem that ordinary spreadsheets and generic finance apps handle poorly: turning scattered receipts into a structured, vehicle-aware history that answers the real question — how much is my car costing me, per kilometer, right now.
