Everything you need to keep track of your vehicle

A clear logbook that surfaces what's due, and works fully offline.

Every vehicle type, one app

Motorcycle, car, bicycle, or scooter — each type comes with its own checklist of maintenance categories, ready to use or customize.

Unlimited vehicles, each with its own logbook
Works fully offline, no internet needed

Needs attention, at a glance

Overdue and due-soon items surface automatically, by mileage or by date.

Minor & major service bundles

Group checklist items into service bundles, so one visit to the shop logs everything at once.

Full history, per category

Every entry keeps its date, mileage, and notes — like brake pad wear or coolant levels.

Export & import anytime

Back up as JSON, share a CSV log, or generate a PDF report — the files are yours, saved wherever you choose.

Free. Private. No catches.

GreaseTrail is built around one principle: your vehicle data belongs to you, and no one else.

No account needed to get started. Read exactly what that means in our privacy policy.
