A history that stays complete

Record every service and incident against the car, with the odometer reading and the tasks performed. Nothing is summarised away and nothing expires.

Know what is due next

Set an interval in kilometres, in months, or both — oil, gearbox, brake fluid, whatever you track. Each schedule shows how far or how long is left, and says so plainly once it is overdue.

Mileage over time

Readings plot on a time-accurate curve, so the slope shows how fast the car is actually accruing distance, with distance-per-year bars over the top.

Your data stays yours

Everything lives in a single local database file on your machine. No account, no cloud, no telemetry. Export the lot to one JSON file whenever you want, and import it back.

What it looks like

The Car Manager dashboard, showing each car with its next due service

The Dashboard opens on what needs attention: every car, its current mileage, and the most urgent maintenance job waiting on it.

The maintenance page, listing each schedule with the interval, when it was last done and whether it is due

Maintenance holds the service history and the schedules derived from it: what the interval is, when the job was last done, when it falls due next, and how much is left — in kilometres, in months, or whichever runs out first.

The mileage page, showing the odometer curve with distance-per-year bars

The Mileage page plots every reading on a time scale, so a quiet winter and a long summer look different — with a bar per calendar year showing the distance covered.

Availability

Car Manager runs on Windows and Linux today. The installers are not signed with an OS code-signing certificate yet, so Windows shows a SmartScreen warning the first time you run one — the download page explains exactly what you will see and how to check the file you downloaded is intact.

Updates are offered inside the app and are verified before they are applied: an update that is not signed by the project's own release key is refused, not installed.
