What you can do in Fuelbook on the web
km/l and cost/km, worked out for you
Every fill-up is measured against the one before it: distance since, litres in, mileage and cost per kilometre — the same maths as the iPhone app, with a live preview while you type.
Metric and two-wheeler first
Litres, kilometres, km/l and cost/km throughout, with bikes, scooters, cars and trucks/SUVs and a currency symbol you choose — no gallons, no mpg.
Every vehicle in its own logbook
Each bike, scooter or car keeps its own fill-ups, services, average km/l, cost per km, total distance, litres fuelled and money spent.
Efficiency trend and monthly spend
Insights charts km/l per fill-up against your best and worst, cost per km over time, and eight months of fuel spend so a vehicle that starts drinking more is obvious.
Service log with date or distance reminders
All eight service types — oil change, tyre pressure, tyres, chain, brakes, air filter, spark plug, general — with the usual interval one tap away, and due-soon at 30 days or 500 km.
Yours, offline, exportable
Everything stays in this browser; export the whole logbook as JSON or your fill-ups with km/l and cost/km as a CSV.

Where is my data stored?+
Only in this browser's local storage. Nothing you enter is sent to our servers, so we can't see it, back it up, or restore it. Clearing site data, a private window, or another device starts empty. Export a backup from the in-app menu to keep it.
Is there a Fuelbook app for iPhone or Android?+
Not yet. Fuelbook is a community proposal: the browser version is complete, and we build the iPhone and Android app once 100 people upvote it. Upvoters get one email when it ships.
