About this app

Can't remember when you last changed the oil? MechLog is the vehicle maintenance log that keeps every oil change, fill-up, and repair in one place. Know what each vehicle costs and what service comes next.

━━━ Why Paper Records Fall Short ━━━

Glove-box receipts fade, notebooks get lost, and spreadsheets stay empty. Six months later you can't recall if the last oil change was at 8,200 or 18,200 miles, whether the timing belt is due, or what you spent on tires this year. MechLog fixes that with a real maintenance log on your phone — quick to update, hard to lose.

━━━ How MechLog Works ━━━

Open the app and a hero card leads with your next service due — the reminder closest by date or mileage, front and center so nothing sneaks up on you. New here? A friendly empty state walks you through your first vehicle and first record. Tap Quick Add to log a fill-up or repair in seconds — date and mileage prefilled from your last entry — and add the rest anytime.

━━━ Every Vehicle You Own ━━━

One app for the whole fleet. Cars, motorcycles, trucks, boats, ATVs, small engines — each with its own history, odometer, and cost record. Switch vehicles with a tap. Up to five vehicles free; Pro unlocks unlimited.

━━━ A Maintenance Log That Works ━━━

Log oil and filter changes, tire rotations, brakes, battery swaps, inspections, repairs, washes, belt and chain service, winterization, and more. Add date, mileage, cost, shop, parts, and a receipt photo — one photo per record on Free, up to five on Pro. Previous odometer values auto-fill the next entry. Pro adds custom service types.

━━━ Fuel Economy Tracker ━━━

Log every fill-up and MechLog calculates MPG, L/100km, or km/L by the full-tank method. Partial fills are handled correctly — no inflated numbers. Watch the monthly trend and catch a fuel leak, a sticking caliper, or an overdue tune-up early.

━━━ Oil Change and Service Reminders ━━━

Set reminders by date, by mileage, or both — whichever comes first. MechLog alerts you before an oil change, tire rotation, inspection, or registration renewal slips past. Three reminders on Free; Pro unlocks unlimited so every vehicle and interval is covered.

━━━ Real Cost of Ownership ━━━

Fuel is the obvious cost. Insurance, parking, tolls, taxes, loan payments, parts, and labor add up to much more. Log them all — one-time or recurring — and MechLog totals everything by category, month, and year.

━━━ Statistics That Tell You Something ━━━

Monthly cost breakdowns, category pie charts, and a fuel economy summary come free. Pro unlocks cost trends, full-year reports, fuel economy line charts, and total cost of ownership — the picture you need at tax time or before keeping a vehicle another year.

━━━ Your Data, Your Device ━━━

Records stay on your phone. No ads. No trackers. Encrypted local backups are free for everyone. Pro adds automatic Google Drive backup so a dead phone doesn't take years of history with it.

━━━ MechLog Pro ━━━

Free: up to five vehicles, unlimited records, three reminders, one photo per record, core statistics, and encrypted local backup.
