A logbook that does the maths for you

Your garage

Add every car, van or bike you drive with make, model, year and fuel type. Switch between them in a tap.

Fill-up log

Date, litres, cost, odometer and notes. Distance since the last fill-up turns into km/l automatically.

Running costs

Total spend, average cost per litre and cost per kilometre - per vehicle and across your garage.

Trends

Line charts show efficiency and cost drifting over time, so a dropping tank average is obvious early.
