iPhone
Boats with engine-hour reminders, iCloud sync, and an optional nudge when you stop at a gas station. Snap the receipt and Logbay fills in the rest.
Logbay is the simple, private gas mileage and maintenance log for your car, truck, motorcycle and boat. No account, no ads.
SNAP THE RECEIPT, DONE
Take a photo of your gas receipt and Logbay reads the gallons, price per gallon and total for you, right on your iPhone. Snap the dashboard to fill in the odometer.
NEVER MISS AN OIL CHANGE
Reminders for oil changes, tire rotation, filters, brakes, inspection, registration and insurance. Logbay reminds you by miles or by time, whichever comes first, and estimates the date from how much you drive.
KNOW WHAT YOUR CAR REALLY COSTS
• Accurate MPG with the full-tank method (also L/100km, km/L and MPG UK)
• Partial fill-ups and missed entries handled correctly
• Cost per mile, monthly spending and every expense: parking, tolls, car washes, tickets
• Compare your real MPG with the EPA rating for your car
RECALLS AND WARNING LIGHTS
• Free recall check from NHTSA data, with an alert when a new recall affects your model
• Snap a dashboard warning light to see what it means and how urgent it is
DOCUMENTS AND RENEWALS
Keep your registration, insurance card, inspection and warranty with photos. Logbay reminds you before anything expires.
SELL FOR MORE
Export a clean, sale-ready service history PDF with every oil change and repair, to show buyers your car was cared for.
BOATS AND MOTORCYCLES TOO
Track engine hours for each outboard or inboard, with reminders for impellers, anodes, lower unit oil and winterizing. Chain care and service intervals for motorcycles.
ASKS WHEN YOU STOP FOR GAS
Optional: when you stop at a gas station, Logbay asks if you filled up, so you never forget an entry. Logbay has no servers and never stores or shares your location.

Ratings & Reviews

• New: How old are your tires? Snap the DOT code on the sidewall and Logbay tells you the tire’s age, whether it’s time to replace it, and can remind you when it is.
• “What’s this light?” now suggests the right light far more often.
• You can now swipe through the welcome screens.
