GreaseTrail

GreaseTrail is a simple, offline-first maintenance log for anything with an engine or a chain; motorcycles, cars, bicycles, scooters, and mopeds.

TRACK EVERY VEHICLE Add as many vehicles as you like. Each one gets its own odometer, photo gallery, and maintenance checklist tailored to its type.

NEVER MISS A SERVICE Set reminder intervals by distance or time for any maintenance category; oil changes, tire pressure, chain tension, brake pads, coolant, and more. GreaseTrail tells you what's overdue and what's coming up, right on your Garage screen.

LOG WHAT YOU DID Record a maintenance entry with the details that matter; odometer reading, measurements, notes, and photos. Bundle related tasks into a single Service visit (e.g. "Minor service") so one log entry covers everything you did.

REUSABLE CONFIGS Build a maintenance checklist once and save it as a Config, then apply it to every new vehicle of that type. Import or export configs as files to share them or back them up.

YOUR OWN COLORS Pick an accent color for the app, or give each vehicle its own — so when you scroll through your combined maintenance log, you can tell your vehicles apart at a glance.

YOUR DATA STAYS YOURS GreaseTrail works entirely offline. Everything is stored on your device — no account, no sign-up, no ads, no tracking. Export a full backup (JSON), a spreadsheet-ready log (CSV), or a shareable PDF report whenever you want.

Whether you're keeping a single daily driver running smoothly or managing a garage full of bikes, cars, and everything in between, GreaseTrail keeps the maintenance history organized so you always know what's due.
