Know what the day really paid.

It records mileage the same way, without a start button. The difference is what happens after: your takings go in, the fuel, parking and running costs come off, and the app tells you what the hour actually paid. A mileage figure on its own never told anyone whether the round was worth doing.

DropLane doesn't keep the GPS running all day. It sits quietly until it notices you've left where you parked, records while you're moving, and goes back to sleep when you stop.

No — and there's no button to press. That's the whole point. If you have to remember, you'll forget on the day it matters.

Nothing is lost. Drives without a type wait on the Days screen, and the app reminds you rather than guessing for you.

No. There's no account and no server. Everything lives on your iPhone, and backs up only to your own iCloud if you want it to.

That works. Cargo-bike miles are recorded the same way. The built-in mileage rates are for motor vehicles, though, so what a bike can claim depends on your country and your circumstances — worth asking an accountant.

Seventeen countries have their official rate built in and kept current. Anywhere else, type your own rate once and the app does the maths.

Yes. Miles or kilometres, your own currency, and the fuel price you actually pay — all in Settings, on the first screen.

Yes. Recording runs off your iPhone's own GPS and wants no internet at all. Drives taken out of signal come back labelled “Start” and “End” instead of street names, and DropLane fills those in the next time it sees Wi-Fi. A week down lanes with no bars still adds up right.

Sign in to the same iCloud and your drives, earnings and expenses come back on their own. There is no account to make and no password to lose, because there was never a server holding any of it — the backup is yours, in your own iCloud.

Nothing is deleted. Your drives stay on the iPhone and in your own iCloud, exactly where they were. But DropLane needs an active subscription to open, so if you want the figures somewhere else, export the CSV before you go. It's in Settings, and it's one tap.

Tell DropLane the price per litre your fuel card charges, then log the litres when you fill up. The cost is worked out on the day, so the week's profit is right weeks before the invoice turns up.
