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 your next service sits at the top — the reminder closest by date or mileage. Did the work? Tap Log service, save the record, and mark the reminder done. Below it you see the current odometer (update it in one tap so mileage reminders stay accurate) and what you have spent this month compared with last month. New here? A three-step checklist gets you to your first record, your first reminder, and your first fill-up. Quick Add logs a repair in seconds with today's date and the current mileage filled in.
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 lets you add as many as you need.
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 ten on Pro. The current odometer reading fills in automatically.
Fuel Economy Tracker
Log every fill-up and MechLog calculates MPG (US or UK gallons), L/100km, or km/L by the full-tank method. Partial fills are handled correctly — no inflated numbers. Free shows your average and a trend arrow; Pro adds a line chart of your last ten full-tank fill-ups, so a sticking caliper or an overdue tune-up shows early.
Oil Change and Service Reminders
Set reminders by date, by mileage, or both — whichever comes first. Date reminders notify you the chosen number of days ahead; mileage reminders notify you once the odometer reaches the target (checked when you open the app or save a record). Every fill-up or service you log moves the odometer forward, so mileage reminders know where you are. Three reminders on Free; Pro lets you add as many as you need 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 — numbers you can look back on when reviewing your records or deciding whether to keep 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.
