When reporting a problem, it helps to include your iPhone model, iOS version, and a short description of what happened.
Open the app after you fill up or charge, and enter three numbers: your odometer reading, the fuel or energy added (litres, gallons, or kWh), and the total you paid. Tap Save — that's it. Date, time, vehicle, and every calculation are handled for you. It takes about fifteen seconds. If you've set your tank or battery size in Settings → Garage, the amount is even pre-filled whenever "Filled the tank" or "Charged to full" is on — just correct it if needed.
Each stop's cost is divided by the distance driven since your previous stop, and the brass line on the chart is a moving average of your last five stops, so one expensive tank doesn't distort the picture. The headline figure on the Trends screen shows this average — or, when you're viewing your whole garage, a distance-weighted figure for the last 90 days.
No. Cost per km never depends on whether you filled the tank. Only the efficiency chart (km/L, mpg, km/kWh) needs full-to-full windows — that's why the app asks whether you filled up or charged to full, and quietly measures efficiency between full stops only.
Yes. Add as many vehicles as you like — petrol, diesel, electric, or hybrid — in Settings → Garage. A hybrid can log both fuel fill-ups and charging sessions, and everything folds into one cost picture. Each vehicle gets its own line on the cost chart.
Runrate follows your iPhone's region automatically — kilometres or miles, litres or gallons, and your local currency. You can override any of them individually in Settings → Units.
Touch and hold your home screen, tap Edit → Add Widget, and search for Runrate. The widget shows your current cost per km/mile, the trend against your previous average, and a sparkline. It updates only when you log a stop, so it uses effectively zero battery.
Settings → Export CSV. You get a clean spreadsheet-ready file with every stop, in both metric and your display units, including computed cost-per-km columns — yours to keep, back up, or analyse.
