iPhone
Real fuel economy, real range — one photo and it's logged.
No car connection, no automaker account: a running-cost ledger for people who actually drive.
The number on your dashboard is a best case — steady speed, no aircon, no traffic.
What you actually get is usually worse.
CarLedger does not guess. It records: snap the pump or the dashboard each time,
and the estimate is rebuilt from your own numbers. The longer you use it, the closer it gets.
[LOG IT WITH A PHOTO]
· Photograph the dashboard — range and battery level are read out for you
· Photograph a charging order — kWh and the amount paid are recognised
· Photograph a ride-hailing payout — logged as income
If something cannot be read, the numbers are still on the photo — just fix them by hand.
[EVERY KWH AND EVERY LITRE, ACCOUNTED FOR]
· kWh/100 km and L/100 km, settled automatically between two refuels
· Cost per kilometre: what that stretch actually cost
· Charging loss: pile-side kWh vs car-side kWh, so you can see where it goes
· Battery health: capacity fade made visible
· Season comparison: how much more winter costs than summer
· "Auto-stop" fuel calibration: enter by gauge marks and still get real litres
[REAL RANGE, AT A GLANCE]
· One number on the Home Screen: how far you can still go, worked out from your own real consumption — not the car's optimistic guess
· Snap the dashboard once: the car's range and current charge are logged, and the estimate sharpens
· Drag the bar: keep a 10% reserve, or set "charge up to 90%", and the usable range is recalculated
· Petrol and hybrid too — real fuel consumption turned into kilometres left
[EV / PETROL / HYBRID / PLUG-IN / RANGE-EXTENDER]
· Battery electric, plug-in hybrid, range extender, hybrid, petrol, diesel — add them one at a time
· Each settles and reports on its own; switch between them to compare
· Saloons, SUVs, MPVs — if it drives on four wheels, it can be logged
[SAY IT INSTEAD OF TYPING]
"odometer fifteen thousand, forty percent left" — say it and the form fills itself in.
[REACH IT FROM ANYWHERE]
· One-tap recognise from Control Centre or the Lock Screen widget — take a screenshot, tap once, it is logged
· Home Screen widget for your daily spend
· Shortcuts and Siri work too
[THE DATA IS YOURS]
Everything stays on this phone and nothing is uploaded. Export to CSV whenever you like.
CarLedger never reads vehicle data, needs no automaker account, and contains no ads.

Ratings & Reviews
Record a fill-up with several screenshots at once: after opening the entry from a Shortcut or the camera, you can keep adding more screenshots and they are recognised together, in any order. Also fixed the status bar at the top of phone screenshots: the clock and the battery percentage are no longer mistaken for the amount and the remaining charge.
