Odograph: Car & Bike Fuel Log

Every fuel app tells you what you spent. Odograph tells you when your vehicle starts getting worse. Log a fill-up and it works out your real mileage — then compares it with your own baseline. When four tanks in a row come in below it, Odograph says so, in plain numbers: "your last four tanks averaged 11% worse than your average." No other log does this, and it is the whole reason this one exists. Any vehicle, not just cars • Motorcycle, scooter, auto-rickshaw, car, SUV, van, truck, bus, boat — or anything else with a tank and an odometer • Pick what it is and Odograph sets the units for you: a bike in km/L, a car in L/100km, a pickup in MPG • Petrol, diesel, CNG, LPG or electric — CNG is measured in kilograms, the way the pump sells it • Service intervals that match: 3,000 km oil on a motorcycle, 25,000 km on a truck, and no oil at all on an electric Mileage that is actually correct • Partial fills, missed fills and full-to-full — handled properly, not silently averaged away • km/L, L/100km, MPG (UK), MPG (US), km/kWh and km/kg — your unit, per vehicle • Cost per kilometre and cost per month, from what you really paid • A tank that cannot be calculated is marked as such, with the reason, instead of quietly distorting your average • A reading that cannot be right — 40 litres into a scooter, 5,000 km on one tank — is questioned before it is saved A fill-up in seconds • Odometer, litres, price — and the total works itself out, or type the total and the litres do • Your last reading and the distance since are on screen while you type • Photograph the receipt and it stays with the entry • No account. No sign-up. Open the app at the pump and you are done Service that follows the odometer, not just the calendar • Tap "Engine oil" and the target is worked out from your own reading and your own daily distance • Intervals by distance, by date, or whichever comes first • A reminder that cannot be projected yet says so, rather than implying an alarm that will never arrive • Every interval is yours to change. Odograph proposes; it never insists Where the money actually goes • Fuel, servicing, insurance, tax, tolls and parts, in one running total • Cost per kilometre over any period • Best, worst and cheapest tank Your whole garage • As many vehicles as you own, each with its own units and its own history • Switch between them in one tap • Arrange the bottom bar around the screens you actually use Yours, and it stays yours • Your log stays on your phone. Every fill-up, cost, note and receipt photo is stored in the app's own private storage — there is no account, no server, and nothing you record is ever uploaded • The ads are the only thing that talks to the internet, and they never see your log. Ad software gets the device's advertising ID and the usual ad signals; it gets none of your entries • Export the lot as a JSON backup file whenever you want, and restore it on any phone Odograph keeps records and counts distances. It does not tell you your vehicle is safe, does not diagnose a fault, and does not decide when a service is due — always follow your manufacturer's schedule and a qualified mechanic. Free, with ads.
