Tankful: MPG & Car Maintenance

Tankful is the logbook for everything you drive, with a mechanic inside: cars, trucks, SUVs, motorcycles, RVs, ATVs, boats and equipment. Track every fill-up and service, know what's due before it's due, and get a straight answer when something makes a new noise.

No account. No sign-in. Your records live on your phone, and you can back them up to iCloud Drive or Google Drive any time.

SNAP TO LOG Take a photo of the pump display, your gas receipt, the dashboard odometer or a shop invoice. Gallons, price, total, date and station fill themselves in.

A MAINTENANCE PLAN FOR YOUR EXACT VEHICLE Decode your VIN or enter year, make and model. Tankful builds the factory schedule for your engine and mileage, or engine hours for boats and equipment (oil, filters, fluids, plugs, belts, brakes, impellers, gear oil) and flags the known weak spots of your model. Push reminders arrive a week before things are due, estimated from how much you actually use it, and the app icon badge shows what needs attention across every vehicle.

CHECK ANY REPAIR QUOTE Photograph the estimate before you say yes. Every line is marked: do it, reasonable, can wait, likely upsell, or ask to see it, with a typical price range and questions to ask the service advisor.

ASK THE MECHANIC Grinding brakes, a check engine light, a smell, a leak. Answers use your car's mileage and service history, tell you how urgent it is, and what it usually costs.

REAL FUEL ECONOMY Full-tank-to-full-tank MPG (or L/100 km), partial fills and missed fill-ups handled correctly, trend by tank, cost per mile and monthly spending.

SWITCH IN ONE TAP Import your history from other fuel log apps by CSV. Export CSV or a full backup whenever you like.

FAST, HONEST ENTRY Pick dates from a real calendar, so logging old receipts takes seconds. Charts for fuel economy by tank and price per gallon over time.

Gas, diesel, hybrid and electric. Miles, kilometers or engine hours. As many vehicles as you own.

AI answers are an informed second opinion, not an inspection. Have safety issues checked by a technician.
